GL screwthread ferrules
Fluoroplastics, for tubing connection. Straight and curved models available, screw connector caps made of PPS reinforced with glass fibre (max. 250°C), ferrules made of PFA, with flexible PFA sealing rim and FPM O-ring. When in use, the contents only comes into contact with PFA (or PTFE - GL25 and GL32)....
Expansion and reduction adapters, borosilicate glass 3.3
Manufactured from borosilicate glass 3.3 which is resistant to heat and almost all chemicals. They meet the highest quality standards according to DIN 12257. They have excellent grinding to prevent airleaks. The bottom part of the ground joints are fire polished....
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....
