Connection system

screw cap GLS 45 with two or three ports (GL 14 thread)

Materials used: PP and PTFE. Flexible modular system. Four different hose diameters (1.6 mm; 3.0 mm; 3.2 mm and 6.0 mm) can be connected. Sterile pressure equalisation is possible through use of membrane filter. Unused ports can be provided with a blind cap.

Typical application: safe transfer of liquid media within a closed and sterile system (evaporation is reduced).

GL 45 screw cap with 2 hose connections


  • Two PP hose connections, curved hose connections on the top side, straight connections on the lower side
  • Ideal for use with elastic, soft tubing 6-9 mm
    (Viton®, Tygon®, silicone)
  • Safe transfer of liquid media within a closed system
  • Highly versatile because the screw cap is based on the standard GL 45 thread
  • Optional filter attachment for sterile pressure equalisation available
  • Dishwasher-proof

 

The screw connections with two hose connections have been specially developed for the connection of soft elastic tubing. These are for example used in biotechnology when transferring media with the aid of peristaltic pumps.
The basis of the connection system for DURAN® laboratory glass bottles are screw caps with GL 45 threads and two hose connection type outlets. The curved hose connections prevent kinking of the tubing. A connection to the bottle bottom can be made with the aid of the hose connections on the underside of the distributing body and tubing of suitable length.
The grey PP core moves freely and allows the vessel to be changed over without twisting of the firmly attached tubing.
