SCAT Air Valves V2.0

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.
