Manufacturer's of Scientific & Coulometric Karl Fischer Glassware

The type of corrosion vessel shown opposite is manufactured from borosilicate glass and has a flat ground glass flange on the top which allows an air tight seal when a multi-port lid is clamped in place (clamp & lid not visible in image). Instead of a standard flat bottom vessel all the same diameter the vessel has a small portion at the bottom of a smaller diameter where the corrosion coupons are immersed on the end of the corrosion probe or corrosion coupon holder. An outer water jacket with two screwthreads is added to allow the circualtion of a temperature controlling fluid. The flat base of the water jacket is close enough to the internal vessel that it still allows for the use of a magnetic stirrer if required.
