Red/yellow. With connecting thread UNF ¼" 28G. Filter membrane made of PTFE/PP with a porosity of 1 µm and integrated non-return valve made of silicone. With service life indicator.
The air valve blocks harmful vapours and ensures safe pressure equalisation in the storage tanks. For PFAS analysis of polyfluorinated chemicals according to DIN 38407-42/ DIN 38414-14.With filter membraneLuer-Lock connectionChange indicator
The integrated non-return valve avoids evaporation of solvents and lets flow ambient air into the bottle in case of vacuum. The upstream PP membrane restrains pollutant particles and other contaminations from outside.Free from polyhaloolefinsLid with aeration opening and Luerlock connectorClip-on service life indicator
