The small and large ones (guitar slides) came out killer, exactly what I was hoping for. Mediums were as expected. Nice work.
O'Brien's Scientific really has it together. The products have been consistent, delivered on time or ahead of schedule. It's rare to find a company that over promises and over delivers. Their customer service is unmatched, communication is crystal clear, they turned our ideas/needs into reality much faster than we could have expected - great job guys!
O'Brien's Scientific Glassblowing provides all of the Schlenk and custom glassware used in my research group at George Washington University in Washington, DC. Their workmanship and attention to detail is outstanding, and I have never received a broken item in shipment. I highly recommend them over commercial vendors, such as Chemglass and Ace Glass. Their quality, prices, and ability to easily customize orders makes them far superior compared to the competition.

I'm glad to be able to give you a strong recommendation.
"I have worked with Donny and Anne through both the University of Illinois and O'Brien's Scientific for six years. I have had them repair and fabricate a large number of pieces of scientific glassware over this time - from Schlenk flasks to vacuum manifolds and custom pieces. Without exception, the finished products are works of art, the turn-around time is short, and the pricing is competitive. They have also shown a keen interest to keep my business by responding promptly to my requests and in a friendly manner. I always recommend O'Brien's to colleagues without hesitation."

I received the chimneys and they were exactly what I was looking for and fit perfectly. Looks great in person. Appreciate the quality work, reasonable price, and FAST service.
(Side note: These chimneys were made and fitted from a sketch, nothing to fit it to in person.)
Every time we get a quote, it comes in under other vendors with a shorter lead time, and O'Brien's work is fantastic. Hard to argue with top quality products at a great price!

After I received the work from O'Brien's, I was blown away by the craftsmanship that they had achieved for the work that I had them do! I will continue to use O'Brien's for all of my glassblowing needs and HIGHLY recommend them to anyone else!
Working with O'Brien's is always a pleasure and we look forward to future designs that we will have them fabricate for us. They have nailed all of the designs that we have had them do and they all meet the strict specifications that we require at our company. We would highly recommend them to anyone that has any glassware needs!!
