Tubing adapters
Ground Joint GL Adapters, PTFE
Black, PPS screw cap with GL45 thread or blue PP, screw cap with GLS80 thread, movable insert with ground joint made of PTFE. Transition from a ground joint to a glass thread. The body can be turned independently from the screw cap. The complete, assembled adapter can be removed and fixed onto another bottle without the risk of disarranging the tubing. Very good chemical resistance, for working temperatures up to max. +250 °C....
Ground Joint Reducing Sets
This set consists of PTFE reducing rings graduated in ground joint sizes 14.5 / 18.8 / 24 / 29.2 / 34.5 / 45 and 60. With these rings, different cone and socket sizes can be connected. For example, it is possible to fit a 14.5 cone into a socket of 45. Also other combinations are possible. With this set you can practically cover all requirements within the lab....
Screw caps GL45, aluminium
The caps are available as a closed-top cap with a high temperature PTFE coated cap liner, or as an open-top cap for use with septum or stopper. Metal closures offer a wide range of temperature tolerances and have a high mechanical strength.
