Overpressure/check valve made of borosilicate glass 3.3

The overpressure/check valve made of borosilicate glass 3.3 offers a safe, precise, and highly reliable way to control gas flows in sensitive laboratory setups. It effectively prevents the unwanted ingress of air or reactive gases into inert gas-supported systems and reliably protects reaction apparatus from dangerous overpressure that can occur during exothermic processes, vacuum fluctuations, or gas evolution.

Due to the excellent chemical resistance, high temperature shock resistance and mechanical stability of borosilicate glass 3.3, the valve is ideally suited for demanding areas such as synthetic chemistry, Schlenk technology, analytics, materials research and all applications where controlled, clean gas flow is crucial.

The precisely manufactured standard ground joint ensures a completely tight and compatible connection with common glassware, allowing the valve to be easily integrated into existing systems. The high-quality workmanship guarantees a long service life, minimal maintenance requirements, and trouble-free operation at all times.

This overpressure/check valve is therefore an indispensable component for all laboratories that work with sensitive reaction conditions and require maximum safety as well as controlled, reproducible gas flow.
