NEW
b.safe Air Valves UHPLC
Material: PP | Temperature resistance: 0 °C to +110 °C |
Chemical resistance: ++ very good
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-return valve with upstream porous PTFE membrane (1 μm), including plug-in service life indicator.
Packing unit Service life Cat. No.
Application:
For removal of eluents. 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 am- bient air flow into the bottle in case of vacuum. The upstream porous PTFE mem- brane restrains pollutant particles and other contaminations from outside. The 6 months service life of the filter can be easily monitored through either activating the display on the cap and exchanging the valve in case of completely red colouring or documentation of the exchange date by hand and clip in the display at the valve.
Better b.safe
One click and the ser- vice life indicator is in place - perfectly visible from any position.

The upstream membrane with a pore size of 0.1 μm made of porous PTFE effectively retains coarse and fine dust, as well as microorganisms 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.
