Safety Bottle Caps

Product Introduction

Wooking solvent safety bottle caps filter incoming air to keep dust out of your mobile phase and prevent solvent evaporation—protecting both the lab environment and your health.

One-way seal to stop evaporation

A built-in check valve automatically closes when the system is idle, blocking solvent vapor and preserving the lab atmosphere.

External microporous filter saves money

Innovative split-body design places the dust-sensitive filter outside the cap, allowing quick, tool-free replacement and lower running costs.

Writable label for easy tracking

A dedicated label panel lets you record reagent details and the installation date of both the safety valve and filter, making routine replacement simple and traceable.
