"Gentlemen,
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."

We entertain all kinds of requests for glass. If we can do it, we will try!

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."

"Dear Tom,

Is it Christmas already? I just received the glass cells and they look amazing! 
Thanks heaps for your great work and fast delivery, I really appreciate it.

Best,
Frauke"

"Hi Guys,

"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."

"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.

"Cheers,

"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."

"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."

"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!
Please feel free to share my comments on your website.

"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."

"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."
