By slightly squeezing the glass bead within the rubber tubing, the diameter of the tubing is deformed and allows fluid to pass.

Properties of BOMEX Glass The Bomex brand glass is produced in a highly automated facility located in Beijing, China. The glass code is BJTY, which is a borosilicate glass type 3.3 as specified by ISO 3585. The Bomex glass products also meet the German ASTM Standards. The glass’ primary attributes are its maximum chemical resistance, minimal thermal expansion, and high resistance to thermal shock. The Bomex glass is highly resistant to permeation by acids, salt solutions, organic substances, and halogens, and it is relatively resistant to alkaline solutions. We supply “Bomex” brand, but at times we may have to substitute non-branded glassware. Delivery times are 8-12 weeks if not in stock for all of our glassware.
