For a number of years now we have been making a variety of glass electrochemical cells in a wide range of sizes and styles, simple and complex, from really tiny to pretty big, with and without jackets. We frequently use glass frits to provide the salt bridge, but also use NW flanges to hold membranes such as Nafion® between cell halves. We can add quartz windows for photoelectrochemical cells as well. Check out the echem gallery;  you'll be surprised by the diversity of this work. You can also see what some of our customers have to say here.

"We needed some specialized electrochemical glassware fabricated and not knowing who to contact I did what almost everyone does, a Google search. Your company name came up first and after doing business with you I can see why. You took the time to find out exactly what I needed before coming up with a design, and went even further in anticipating the operational challenges I might encounter and made the proper design accommodations. I was extremely pleased with the outstanding quality of the craftsmanship of the glassware given the very tight tolerance we required. The membrane sealing system design is extremely robust, provides uniform circumferential pressure and is very leakproof, which is no small feat considering membrane sealing is not trivial.
I was especially especially gratified with your patience and cooperation as my needs evolved, requiring some design changes.
And all for a very reasonable price. I look forward to any future projects."
