Highly versatile because the screw cap is based on the standard GL 45 thread. Ideal for use with elastic, soft tubing 6 to 9 mm (Viton®, Tygon®, silicone). These are for example used in biotechnology when transferring media with the aid of peristaltic pumps. Two PP hose connections, curved hose connections on the top side, straight connections on the lower side. Optional filter attachment for sterile pressure equalisation available. The grey PP core moves freely and allows the vessel to be changed over without twisting of the firmly attached tubing. Temperature resistant up to +140°C. Autoclavable, dishwasher safe. Typical application: safe transfer of media within a closed and sterile system.
