Screw Cap GL 45 w/ 2 hose connections
Ideal for the connection of elastic, soft tubing, which, for example, is used in biotechnology when transferring media with the aid of peristaltic pumps. The curved hose connections prevent kinking of the tubing. The grey PP core moves freely and allows the vessel to be changed without twisting of the firmly attached tubing. Sterile pressure equalization is possible through use of membrane filter.
