b.safe Cap PFAS Analytic, free from polyhaloolefins, unrestrictedly switable for PFAS analysis.

• Screw cap made of PPS for thread GL 45
• Freely rotatable insert made of PP
• PE fittings for capillaries with outer diameter 3,2 mm
• Blind fittings made of PE to close connections which are not needed
• Aeration valve (filter membrane PP) with change indicator

Perfectly matched system for extraction of eluents in context of the PFAS analytic. Tubing can be inserted onto the ground of the bottle by means of the b.safe Fittings made of PE. The conical seal cone clamps the tubing and seals the connection safely.

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 six 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.
