SCAT Air Valves

SCAT air valves for safety caps block solvent vapours and keep your solvents clean.  Suitable for use for both analytical and preparative applications, these air valves contain a PTFE filter to continually block the passage of vapour and dirt.  Since the filter membrane absorbs contaminants from the surrounding air, it is necessary that the valve be replaced every 6 months to ensure problem-free operation.
