Applications

Safe disposal of solvents without leakage of harmful solvent vapours. With b.safe Fittings made of PFA, tubes can easily inserted in the waste container, the conical seal cone clamps the tubing and seals the connection safely. Through the connection of tubing with I. D. 5,5-8 mm respectively through the Filling Funnel directly from flasks, large amounts of liquids can be disposed of. The integrated stopcock avoids leakage of harmful vapours through the filling hole. Solvent vapours from the escaping air during filling are restrained through the Exhaust Filter containing activated carbon. The service life of the filter can be easily monitored through either activating the display on the lid and exchanging the filter in case of completely red colouring or documentation of the exchange date by hand.
