Honeycomb denuders

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.

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.

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,

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, Mark Dansson

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.

Cheers!

Hi Tom Thank you very much for making a specific photoelectrochemical cell with a perfect optical window. The quality is excellent and the price is reasonable. Thank you again for the excellent work. Weixing Lu Research Scientist Physical Optics Corporation

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.

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.

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,
