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."

We have been getting a lot of requests for repairs of wiped film distillation glassware like the one pictured above. Here's another;
"... 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. "

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’t 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’s 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."

"Dear Tom RL Goodwin, PhD |
 |
| "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. Jessica Kachian, Ph.D." |

"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. |

| "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." Petros Koutrakis, Ph.D. Professor of Environmental Sciences and Director of the Environmental Chemistry Laboratory Harvard School of Public Heath |

"Hello Tom, "Cheers, |
|

"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!" Chiaki Treynor, Ph. D. |

"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." Joel Johnson |

"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." Best regards, |

| "Hey Tom, Hope this finds you well and all is good. As promised, attached is a photo of the “coupon rack.” We are proceeding with the installations this week and when I get one of the units up and running I’ll send you another photo. If these racks work as well as we hope I will be ordering the additional 60 units for the rest of the campus hot water loops. Tom, you were a great help with this project and Ga. Valve and Fittings, the Swagelok supplier, was really impressed with the results and how it all came together. To coin an old southern saying “we did good.” Thank you for all your help." Phil Stephens Emory University |
| "Mary, Tom, George, I just wanted to drop a line because I was thinking of you. I’ve 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’t 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’ve 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 “Why can’t they be like Adams and Chittenden?!” Thank you for the outstanding level of customer service and just for being really nice people who I like doing business with." Marlene Hoeber Manager of Lab Services Amyris Biotechnologies |

"Hi Mary, |
|
"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’s 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." Kathryn Allegra |

"Dear George and Team: Thank you so much for the expedited service on the wine SO2 apparatus...we are relieved that it will be available. We needed it in an emergency and having it ready in just a few days is clearly the type of service one can expect from Adams & Chittenden. We are looking forward to using the new apparatus and, since we have one of your cash stills, can rest assured that it will be of the same superior quality. Thank you! |
 |

"Just wanted to give you a big thumbs up for your SO2 apparatus which I use for measuring free SO2 in hard cider. I started using this apparatus a few years back and have used the same apparatus for hundreds of tests without having to replace it. It is durable and easy to clean which noticeably increased my efficiency. Now, starting my own cidery, I am happy to purchase your excellent glassware for my own use. Thank you for everything, |

"Hi Mary I know we just received this cylinder but we like you guys so much we would like to order another. We have found that they do not hold up well to falling off tables and coming in contact with concrete flooring! Thanks" COLIN A. LEVI 95273 |
| "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 “Made in Berkeley” sticker on all my custom glassware." Chris Carreras, Ph.D. |

| "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. thanks, Barry Levine Chiron Corp." |

"Once again, you have astounded me: with the quality of the glass apparatus you fabricated for me, and with the timeliness with which you completed it. Upon reflection, I should not be surprised. 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." Michael C. Rey |

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’t work, said there wouldn’t 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’t 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 “Whipper Snappers” here, that it is OK to try something that you have thought through without analyzing to death first! On a side note, I had a 6 foot piece of 1 ½” white PVC pipe going from the cyclone to the vacuum motor. A couple people were having a fit that I used white PVC in the system. So I went to the local hardware store, a bought a can of aluminum colored spray paint and painted the pipe. Those same people were amazed I was able to get a piece of “aluminum pipe” that fast. And they are convinced it works better now. Kids….sometimes all I can do is smile and shake my head. 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." Admiringly, Jim Hodgson, Fellow Glassblower Kansas State University |
