Borosilicate electrochemical cells are widely used in chemistry, materials, and chemical engineering labs worldwide for various applications, including catalysis studies, the development of sensors and batteries, and fundamental inorganic chemistry research.
Borosilicate electrochemical cells can range in size and style. Still, we make these to reflect the specific needs of our customers: simple and complex, manufactured to an extensive range of volumes, with and without jackets, and any other variation you may require.
We can use glass frits to provide the salt bridge, flanges to hold membranes between cell halves, and add quartz windows for photoelectrochemical (PEC) cells as well. We can also offer various port options for electrodes, although we recommend threaded styles, such as GL14, equipped with caps, seals, and septums for the safe insertion of probes. Our expert scientific glassblowers can tailor everything to your specifications.
Additionally, our cells can be made to host a variety of working electrodes, including our very own platinum flag electrodes.

The Platinum Flag Electrodes from Asynt are made with only the highest purity materials, designed and built around your electrochemical application to be robust and effective.
We have electrode specialists that supply all the materials (Pt wire, Cu wire, Pt flag) that are incredibly high purity, which is challenging to source otherwise.
As a standard, we build these with 1.0 mm Cu wire, 15mm length/0.38 mm thickness Pt wire, and 0.02 mm Pt flag thickness, but we can specify each length and thickness according to your requirements.
Design parameters include:
• Length, width, and thickness of the platinum flag
• Total length and thickness of the platinum wire, length that protrudes out of the glass from the bottom
• Total length and thickness of the copper wire, length that protrudes out of the glass from the top
• Total length and diameter of the Pyrex glass stem
• Optional: to back up the platinum-to-glass seal with a potting compound
