This system allows to fill three stations from one reservoir at the same time. A sterile pressure division system can be positioned at the fourth exit. By means of a M8 screw cap with opening and inserts (with and without openings in different diameters), hoses with a diameter of 1,6 and 3,2 mm can be used. Unused exits can be shut with an insert without opening or used as septum to add yet something later on.The Duran® lab flask has a special form on the basis of the ISO 4796 standardization and is pressure and vacuum proof within the range of -1 to +1,5 bar. The pressure resistance is tested on safety in accordance with EN1596 and certified according to TÜV GS. High safety by the possibility of a locked system.Employable in different manners because the basis is a GL45 screw cap. The components are autoclavable. Multiple use of components possible. The silicone insert without opening can also be used as septum. Through this, adding liquids by injection afterwards is made possible. Several hose diameters can be put in (1,6 mm / 3,2 mm). Modular system: only the necessary can be ordered. Graduated.
