Screw cap for GL 45 bottle thread made of PPS with freely rotating distributor body made of PTFE, selectable with two, three or four connections. Connections with UNF 1/4″ 28G inner thread for connecting PFA-fittings for hoses (external diameter 3.2 mm), PFA dummy stoppers for the closure of unnecessary connections or a venting valve with change indicator.
For removing solvents for HPLC. Freely rotating distributor bodies, prevents the hoses twisting when replacing the bottle. Using the fittings, hoses can be introduced up to the base of the bottle; conical nipple clamps the hose and seals reliably at the connection. The venting valve is specially adapted to the flow rates in HPLC; integrated non-return valve prevents the evaporation of solvents and lets ambient air flow into the bottle in the event of a vacuum. The upstream membrane made of porous PTFE effectively keeps out dirt particles and other contaminations from outside. Venting valve with change indicator after activation at the press of a button and with labelling area
