Product description

Screw cap made of PPS for thread GL 45, free movable insert made of PTFE. With PFA fittings for capillaries with O. D. 3,2 mm (UNF 1/4") and an Air Valve with service life indicator. All capillary connectors with integrated stopcock, connection to the bottle ground through additional capillary connector on the bottom side of the lid. Version and scope of delivery as per below chart.


Perfectly matched system for removal of eluents. By means of the 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 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.
