Here's a response to a repair job.
"We received the repaired borosilicate reactor top today, where you installed a new fitting where we had broken one completely off, with sharp edges and hairline cracks.
I wanted you to know that we really appreciate your impeccable workmanship, your quick turnaround time, your reasonable price to perform the repair, and the fact that you are one of the few companies that we could find in the U.S. to do this work....

We recently received this unsolicited note from an old-time client

"Dear Tom,
I want to express my thanks to you for all the help you&rsquove given to me and my group over the years.  From last-minute repairs to innovative thinking about new designs that could achieve our goals, you and your team have made a big positive impact on our research......
...I&rsquom so glad your business is set to continue well into the future.  The science community needs it."

Sandia researcher David Osborn

A local postdoc was referred to us by their Stanford colleagues as a source for custom glassware needed for an electrochemical ammonia synthesis project. Working from previous work we had done for their department, he submitted his ideas for a cell that would best suit his purposes, which included a low volume cell that could hold a vacuum while being moved in and out of a glovebox. We worked with him on his ideas, and were delighted to get his response to his custom glassware.....

"Adams & Chittenden worked with me to design the perfect glass vessel for my postdoctoral research. They discussed design considerations with me over the phone and sent me multiple iterations of sketches via email until the design was to my liking. Their attention to detail, responsiveness, and professionalism are second to none. I also chose the expedited option (so I could start experiments as soon as possible with the new vessel), and I received the vessel exactly 3 weeks from the day the PO was sent - just as they had promised. Count me as yet another life-long customer."

Adams and Chittenden helped us to customize 5 sets of electrochemical cells for our laboratory experiments.
We appreciate George for putting time and effort into understanding our custom design needs. 
It was a bit expensive for us but the quality of glass compensated for it. The support, design and quality were excellent and up to the mark.
Just a phone call away to understand & update your order details!
Thank you very much Moe and Stefka for your continuous support.
Best wishes!!

Once again you saved me. Words cannot describe my gratitude for all you do. In the past, it never seemed "TOO DIFFICULT" to me when I asked for a glass repair. This time, I knew things were different. The column you repaired came from a machine manufactured in Germany. A replacement would take time and cost a small fortune. You repaired it and its working good as new!
Truly a pleasure working with you. Artisans are a lost breed, for sure. You not only do fantastic work, you provide great service at very fair prices."

"... All that being said I can't possibly express how pleased I have been with this experience. Your professionalism and communication has been first rate! We all cringed when you said you had to cut the top off to get the collar off...better you that us!!! Thank you again for expediting this repair, I'm anxious to get my baby back up and running.
                            All the best Chris."

"We went to Adams & Chittenden on recommendation since we needed to special order three-electrode W-cells for electrochemistry experiments. The cells came out immaculate, exactly to our specifications and needs! We can determine exact concentrations of redox-active species with these cells. Our glassblower was very flexible with us in working out the kinks in our original design. Thanks for the craftsmanship and professionalism."

A happy customer writes about a standard piece of laboratory glass doing what it is supposed to:
"I had remembered seeing in a photo some time back of a sep funnel ( I didn&rsquot know what I was looking at at the time) thanks to random guesses, images on google and voila - -  I found you guys. Attached is your wonderful work doing its thing. 
What&rsquos awesome is that, it takes very little time for it all to settle out, the waste is only about 2ml of liquid, and the offender. It made our weekend, and saved this product.  Thank you to everyone at Adams & Chittenden."

We had a request from a researcher:
"We need a piece of glassware to help us with a study of the rate of water or solvent flux from a mixture of solvents through a membrane. We think an electrochemical H-cell would do the trick..."

He was clear conceptually, and happy with the result
"Hi Tom,
I received the membrane flux-o-meter today and I have to say that you guys did a phenomenal job with it. The flaring at the end of the pipet is a really nice touch too. I couldn't be happier with the purchase. Thank you once again."

"Adams & Chittenden Scientific Glass exceeds expectations on all indices. They were able to complete a custom chemistry glassware request in a very short amount of time and did so without any sacrifice to quality. During the very short and intense fabrication period, they frequently contacted me with questions highlighting their attention to detail and desire to meet customer needs. I assure you that they went above and beyond in doing so -- top product quality and customer service. For future glassware needs, Adams and Chittenden will certainly be my go-to.

"It is my pleasure to provide a recommendation for Adams & Chittenden Scientific Glass. We have been doing business with Adams & Chittenden since they first opened in 1993. Over the years they have made many different types of prototype parts for our specialized research applications.
My first experience with them was on a project we had to develop an inexpensive sampler for separating airborne, submicrometer particles from their gas-phase vapor counterparts. A colleague of mine, a professor at Harvard University, sent me a glass honeycomb he had designed for this purpose. While this one prototype performed superbly, it was a one-of-a-kind. Harvard informed me that their glass shop could not make these on a consistent basis. Indeed they invested quite a bit of money in a nearby glass shop resulting in many globs of melted glass, but no honeycombs. In contrast, when I approached Tom Adams, he was able to fabricate the honeycombs on the second try, and to do so consistently thereafter. Adams & Chittenden now routinely make these for Harvard University, and for their licensee.
As you can see by this example, Adams & Chittenden love the challenge of making new things. Without question, they are highly skilled as glass blowers. Not only do they deliver quality products, they deliver them on schedule. The are organized and fair regarding business matters, and are reasonably priced. Moreover, they are very pleasant people to work with. I recommend them highly, and without reservation."

Denuder w Decaled Number (/images/uploads/2249_5e275ba8dde9b.jpg)

"I would like to acknowledge the successful relationship the Harvard School of Public Heath Environmental Science and Engineering program has had with The Adams & Chittenden Scientific Glass Company.
Three years ago, we were developing a sampler to monitor airborne acidity. We had developed all of the mechanical parts, but were having a terrible time with the glassware. The performance of the sampler depended on a relatively complex piece of glassware, called a denuder, that was proving almost impossible to build. We had been working with a number of highly regarded glass companies, but the denuder that resulted from these efforts could not be used.
Then, a colleague put us in touch with Tom Adams and George Chittenden, and in a short time, the denuder was completed. The process took a few iterative steps, but each denuder worked better than the last. The finished pieces reflected an understanding of our needs and the high degree of skill that Tom and George have with their medium.
The product that they build is of high quality and is delivered on time. Although it is a fairly complex piece of glass, and difficult to build, the denuders are very consistent. Their fit and finish as well as their performance are up to our needs and standards.
If I could collaborate with more craftspeople of Tom and George's caliber, my work would be a lot easier. As a result of our successful relationship with The Adams & Chittenden Glass Company, I strongly recommend their expertise to others."

"Hello Tom,
We got it this afternoon and looked at it. You, plural or singular, depending on how many worked on it, have done an amazing job and we are very happy with how it looks and feels. The joints are very smooth and the whole arrangement is very sturdy. Everything seems to have been made perfectly to spec and it is beautiful to look at, beyond what I even could imagine. Having stared at it for many hours on a monitor makes it somewhat surreal to see it in reality.
The plug design is perfect and we thank you for that added design input. We will be sure to spread the word to other labs in case they need some custom glass work done.
Thanks for your services, and we will stay in touch, as we put the equipment to use. If it turns out as well as we expect, we may be ordering a piece or few more, so keep the designs in file.

Mark Dansson


"The Adams and Chittenden team was truly a pleasure to work with from day one until project finish. Mary and Tom were very accommodating from day 1: "Can you do one piece of this?", which quickly evolved into "Can you do several thousand of these? Like, tomorrow?" Not only were they able to meet our very tight deadlines and quality requirements for our very unique project, they were able to handle the logistics of procurement and material flow (this involved buying up stock in the entire country, and borrowing space from neighbors.) They remained in close touch throughout the project, and welcomed visits and discussions. Having worked with a multitude of vendors and suppliers, I can only dream that all suppliers would live up to their standard. I have no reservation in recommending them for any scientific glass work, small or large!"

"Here at Asta Glass - Distinctive Barware, there are no PhD.'s on the payroll, we aren't likely to find the cure for anything, and we can say with confidence that we won't ever be on the short list for a Nobel Prize. Nonetheless, our project was given attention and executed with care and precision by the wonderful people at Adams and Chittenden.

Adams and Chittenden make the tiny glass loops we use as "ears" on some of our martini and champagne glasses. They must be of even size and smoothly cut in order to adhere firmly to the glass - and they are. Tom and George have developed and tried various methods of production to improve quality with each batch and keep costs reasonable. Mary has coordinated with us to ensure that we were satisfied with each order and has kept us constantly supplied with loops in order to keep our production on track. That kind of good communication and good service has taken the stress out of what could be a troublesome item to source.

As the owner of a small business, I value being treated courteously and having suppliers come through for me. I think I can also thank you on behalf of the hundreds of people who own our Carmen, Lola, Flora or Stella glasses and who have enjoyed a good drink in them."

"Everyone has been in our situation occasionally: you have a contract with a short fuse, your customer is breathing down your neck and you order the wrong size of something. A chill runs up your spine because it was a custom part and customs take time. Adams and Chittenden made new parts and shipped within 24 hours. It is truly wonderful to find a responsive supplier these days and Optical Subassemblies is grateful for your "above and beyond the call of duty" effort."

"Dear Tom,

Just would like to express my sincere appreciation and thank you for providing us an emergency help during our experiment today. Without your just-in-time repairing of the quartz rod and tube, our silicon wafers would have to stay in the furnace through the New Year's Eve, and for sure, would be damaged. Your generous help not only saved our expensive wafers, but the most important, saved our valuable experiment data. Your help really made it possible for our development project to reach an important milestone before the New Year."

"Good morning Mary,

I just received the reactor head this morning and was very pleased with the work, my supervisor couldn&rsquot even tell which joint of the reactor was replaced. I will be sending my two other reactor heads to you shortly.
Thank you for your excellent service and workmanship."


Ismael Palacios

We received our NW25 cell on which you repaired the flange that we broke. We marveled as we tried to find the repair where the new met the old. The smart money was betting that you sent a completely new cell since we could not find any evidence of the repair! I feel we are stealing since we not only get the functional pieces for our research work but are also getting beautiful works of art. Compliments to the person who repaired our piece for their artisanship.

p.s. give Mary a raise for being the knowledgeable and friendly voice of your company."

"Dear Adams and Chittenden Team,
I want to thank you for the incredible service we've repeatedly experienced while working with you. When we were setting up our labs a few years ago, Tom was able to decipher my bad drawings and rough ideas to design and fabricate our high vacuum synthetic lines along with all the miscellaneous glassware we needed. Since then we've been spoiled by quick turn arounds with new jobs including reactors, adapters, and on-site repair jobs. At least twice Tom has been able to quickly get us up and running with on-site repairs that I had feared would require a complete shutdown. I've referred colleagues to A&C in the past and will continue to do so. I want to thank the entire team at A&C (especially Tom and Mary) for their responsiveness, quality of craftsmanship, and professionalism. I look forward to coming to you with future projects."

"Mary, Tom, George,

I just wanted to drop a line because I was thinking of you. I&rsquove been having a frustrating time lately with various vendors, but you guys are never a problem. I always get what I was promised when I was promised it from you. That might be what many people would expect as the usual for a vendor, but I have come to find that it is a pleasant rarity.

I am especially impressed considering the specialized field you are in. If everything came a month late from you, I would probably still be a customer. If your shop was not a place I actually like to visit, I would still be a customer. If I couldn&rsquot expect useful and experienced input from you in my problem-solving process, I would still be a customer. Getting all of those things makes me feel like I&rsquove hit the jackpot.

Last week, I was dealing with the logistical problems caused by late delivery of the wrong thing from a vendor who seemed not to care about my business. As I was running up and down the halls, pulling my hair out, I asked the empty hall &ldquoWhy can&rsquot they be like Adams and Chittenden?!&rdquo

Thank you for the outstanding level of customer service and just for being really nice people who I like doing business with."

Thanks again,

"I learned about Adams and Chittenden three years ago when I needed glass repairs on a French-made electric ebulliometer. They did a fantastic job with minimal specs and a short turn around time. Since then, I have gone to Adams and Chittenden for all of my wine analysis glassware. In the laboratory, we use the Adams and Chittenden wine thieves daily for sampling and tasting. I love the assortment of styles and their consistent, high throughput design. I have used the AO apparatus for three years now and in my opinion, it is the best design in the industry. It is easy to clean with minimal glass and has increased our laboratory&rsquos efficiency.

I am never afraid to approach Adams and Chittenden with custom projects and special requests. Their customer service is phenomenal I always know the product will be made beautifully and on-time. I highly recommend Adams and Chittenden for any scientific glassware need."

"I have had the pleasure of utilizing the expertise of Adams and Chittenden recently for a custom glass order for a time-critical project at my company. After describing my custom request to Adams and Chittenden during an initial phone call, their professional and friendly manner of operation made the entire process from concept to finished product run in a very smooth and timely fashion.

For my application here at Inhale Therapeutics, Adams and Chittenden constructed a custom glass spray-drying chamber with accurately place quartz viewing panes for laser-based diagnostics. From my perspective as an engineer who works with very tight tolerances in a range of optical applications, I found the work of Adams and Chittenden to be of very high quality and I will not hesitate to approach Adams and Chittenden for my future glass blowing needs.

In addition to the high quality of work and timely service I have received from Adams and Chittenden Scientific Glass, I have found both Tom Adams and George Chittenden to be very personable and bright-minded people who clearly have a mastery over their trade."

"I want to thank Adams and Chittenden for providing a simple solution for my complex glassware needs.   Our Hungarian-made organ bath system seemed like a perfect choice for our ex vivo assays - until the stopcocks began to break. Replacement baths were expensive and required over a month of lead time to obtain. Adams and Chittenden repaired the broken baths, using beefy stopcocks that made the repaired units stronger than the originals. When the scope or our experiments expanded, Adams and Chittenden provided a redesigned unit with increased functionality. Their attention to detail was crucial for this complex piece of glassware - they even used European glass tubing for the fabrication so that the new baths could be seamlessly integrated with the other parts of our existing system. Our new organ baths were also an exceptional value - while they are stronger and more functional than the original units, the quality did not come at an unreasonable cost. Adams and Chittenden's prompt, friendly service makes me want a &ldquoMade in Berkeley&rdquo sticker on all my custom glassware."

"Hi Tom,
After using the jacketed addition funnel a couple of times, I couldn't be happier. Much better than the version with the conventional stopcock. Glass always introduced grease contaminants (never tried Krytox), teflon always shrank and leaked when it got cold. This thing's perfect.
Better make me another one when you have time/capacity. I feel covetous eyes on me already.

Over the years, Adams and Chittenden consistently have exceeded my expectations. I have lost count of the occasions I presented Tom or George with a rough sketch illustrating approximately what I wanted, and from my crude drawing they made something beautiful and perfectly suited to my needs. Not only are Adams and Chittenden consummate craftsmen, but they consistently demonstrate a commitment to outstanding customer service."

From an unsolicited email about a past project:

"This is a little FYI regarding the cyclone you made for me almost a year ago.  I took a lot of flak for
1    Not going to a known supplier
2    Not buying a proven powder transfer system for $10K - $60K with a 12 to 20 week delivery time
3    Not having CAD drawings
4    Not having CAD models of the cyclone predicted performance
5    Not having a cyclone manufacturer design the cyclone
6    Using glass instead of stainless steel
7    Using an industrial floor care vacuum motor as a vacuum source

They had 3 young engineers model and  analyze it here.  They all said it wouldn&rsquot work,  said there wouldn&rsquot be enough air flow.  Said the cut size would be wrong resulting in too much wasted product.   I am pleased to report that my $1500 powder transfer system has worked flawlessly since day one.  It is the only part of the system that hasn&rsquot had to be modified, redesigned or replaced.  You being able to take my hand drawn sketch and turn it into a functioning cyclone was remarkable.  It only operates for about 5 minutes, twice a week.  But when the blower is turned on, people in the shop stop what they are doing and stand in front on the cyclone to watch the powder swirl around.  If a customer tour of the facility is planned, they try to schedule it around the powder transfer time so the customers can watch the powder swirl through the cyclone and into the transfer container.  It is the only point in the process where you can actually see anything happening.  Everything else is stainless steel.   CAD models are fine but I am old enough to prefer being to see what is really happening in a test/R&D/proto type environment.   Your cyclone has helped me prove the point to some of these young &ldquoWhipper Snappers&rdquo here, that it is OK to try something that you have thought through without analyzing to death first!

Thank you again for your help.  It makes me smile when I watch people watching it work."

"Adams and Chittenden did a fantastic job on custom Schlenk lines for our laboratory. Tom in particular was personally involved and extremely helpful in all aspects of the project, from design to execution. We even looked over the design together to determine improvements that could be made to increase the usefulness and lower the cost of the order. The quality of the glass work is second to none. I would like to say a big thank you to all the folks who worked on the project, it was a great experience and we will definitely recommend you to anyone with custom glass needs."

"Dear Tom and George,
I was just on google looking for some images of Schlenk lines and one of yours popped up. Of course I went to your website and meandered through some of your other pictures of apparatus you have made. The thing I have always admired about Adams and Chittenden is the quality and cleanliness of your work.
I love scientific glassblowing and being a scientific glassblower so it is always painful to me to see shoddy work or to hear glassblowers talk who obviously don't care much about their profession. So, periodically, when for one reason or another I visit your webpage, it always gives me a lift to see well done and beautiful work.
So, thanks for your good work and the pictures for everyone to see that show what good scientific glassblowing can be."

"About Adams & Chittenden and crew:
I have experienced yet another stroke of concept-to-practical genius. I came to Adams & Chittenden with the idea for a vacuum dessicator. Our application is to be able to dry any sized fritted funnel upright to avoid costly material loss due to tipping. Naturally, there were specific dimensional requirements, time concerns, as well as safety issues regarding vacuum vs. glass thickness. In a very timely response, the filter funnel dessicator unit was manufactured for us and has provided my chemistry group with countless hours of uneventful successful use since its introduction into production here. This is a flawless piece of glassware for a chemist.
On a more general note, I have approached this group of glass magicians with a vast array of conceptual glassware projects resulting in immeasurable success. This is, of course, not to mention the years they have restored/repaired all the disheartening glassware cracks and splinters.
Thank you for your consistently excellent services."
