Screw cap made of PPS for GL 45 thread, free movable insert made of PTFE.

• PFA fittings for capillaries with outer diameter 3,2 mm
• Blind fittings made of PFA for closing connections that are not required
• Aeration valve with changeover indicator

Perfectly matched system for extraction of eluents. Tubing can be inserted onto the ground of the bottle by means of the b.safe fittings made of PFA. The conical seal cone clamps the tubing and seals the connection safely.

The b.safe Air Valve UHPLC is especially adapted to the flow rate in UHPLC. The integrated non-return valve avoids evaporation of solvents and lets flow ambient air into the bottle in case of vacuum. The upstream porous PTFE membrane restrains pollutant particles coarse and fine dust, as well as microorganisms carried by it and other contaminations from outside.

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. Mobile phrase caps are a practical and flexible closure option in laboratory supplies, which ensures efficient operation and optimal sealing.
