Overpressure/check valve with side glass tap 3 mm made of borosilicate glass 3.3

The pressure relief/check valve with a 3 mm side-mounted glass stopcock, made of high-quality borosilicate glass 3.3, is a specialized safety and control element for sensitive laboratory setups. It reliably protects reaction and Schlenk systems from dangerous overpressure while simultaneously preventing the uncontrolled backflow of air or gases into vacuum- or inert gas-supported apparatus. This ensures the integrity of sensitive reactions is maintained at all times.

The laterally integrated 3 mm glass stopcock allows for precise, sensitive regulation of gas flows and offers additional flexibility in controlling supply or discharge lines. Thanks to the excellent chemical resistance , mechanical stability, and thermal shock resistance of borosilicate glass 3.3, the valve is ideally suited for Schlenk technology , vacuum work , syntheses , gas dosing , and demanding research processes.

The precisely manufactured standard ground joint ensures a completely leak-proof, compatible connection with common laboratory equipment such as reaction flasks, distributors, or condensers. The high-quality workmanship guarantees a long service life, minimal maintenance, and reliable, trouble-free operation in daily use.

This valve is therefore an indispensable component for safe, controlled and reproducible workflows in professional laboratory environments.
