b.safe GL45 Extraction Cap & Air Valve

Description

b.safe At Extraction: Safety and Efficiency From The Beginning

Perfect protection from hazardous vapours, reduction of expensive solvent losses, guarantee of pure eluents and easy handling.

HPLC challenges lab experts variously, especially through precise results, economic processes and high reliability at best protection from hazardous chemicals. Our solution are the new b.safe Caps being equipped with all that is important for safe, economic and easy solvent extraction.

b.safe Caps provide tight closure of the extraction flasks and safe extraction of eluents through the connected capillaries, preventing hazardous solvent vapours from escaping; mixing ratio stay constant and eluents are protected from environmental influences.

Applications

Perfectly matched system for removal of eluents. By means of the b.safe Fittings made of PFA, tubing can be connected to the capillary connectors. The conical seal cone clamps the tubing and seals the connection safely. Through additional capillary connectors on the bottom side of the lid, you can lead tubing onto the bottle ground. Dripping from connected lines during bottle exchange can be avoided through the stopcocks. Unused connectors can be closed if necessary. 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 porous PTFE membrane 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.
