b.safe Air Valve PFAS Analytic, free from polyhaloolefins, suitable for PFAS analysis wit- hout restrictions.Valve body made of PP with connection (thread UNF 1/4“ 28G) suitable for b.safe Caps. Lid with aeration opening and Luerlock connector, integrated non-re- turn valve with upstream PP membrane (1 μm), including clip-on service life indicator.

Application:
For extraction of eluents in context of the PFAS analytic. The b.safe Air Valve is especially adapted to the flow rate in HPLC. 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, but does not interfere with the sensitive PFAS analytic. The 6 months service life of the Air Valve can be easily monitored through either activating the display on the service life indicator and exchanging the valve in case of completely red colouring or documentation of the exchange date by hand and clip on the service life indicator at the valve.

The upstream membrane with a pore size of 1 μm effectively retains coarse and fine dust, as well as microorga- nisms carried by it and other impurities from the outside.
One Luerlock connector, diverse possi- bilities such as filling the solvent with gas to protect it from oxidation.
Or comfortable connection of dry tubes to keep humidity outside.
