b.safe Air Valve HPLC
PP for high re- sistance and fire class rating V-0
Centring pin for easy installation
The handy b.safe Air Valve provides the necessary pressure compensation during solvent extraction. Furthermore, it restrains pollutant particles from the bottle content and lets flow as much ambient air as necessary through the lid and the inside PTFE membrane (pore size 1 μm) for guaranteed six months until exchange.
In order not to forget this, the Air Valve has a practical service life indicator with activation through the touch of the button as well as a title block for documentation in GMP/GLP regulated laboratories. The valve is easily mounted and demounted, even with gloves, through the large head, eroded surfaces, grooves and strongly connected parts.
The universal Luerlock connector offers diverse opportunities for special applica- tions such as oxidation protection by filling the bottle with inert gases as well as the adaptation of dry tubes to maintain water-free eluent mixtures.
At least, the b.safe Air Valve made of PP offers high chemical resistances and a fire class rating V-0 as per UL 94.
Freely movable and individually positionable for all round visibility
Non-slip grip area, eroded surfaces and gripping grooves for easy installation
Activation of service life through touch of the button and/or indivi- dual marking on the back side
