Flat-face quick-disconnect coupling, product series DBG-CSP, dry-break type
Uncontaminated biological cultures can only be produced in an aseptic environment using installations that warrant absolute tightness. It is mandatory that the virulent microorganisms are safely handled. The lines leading into the bioreactor to add media and take samples are usually closed off by means of diaphragm or ball valves. The design of ball valves allows for dead spaces in the valve which entails cleaning requirements. Diaphragm valves often give rise to the formation of aerosols which constantly act on and cause brittleness of the diaphragms which must then be replaced resulting in higher maintenance efforts.
GATHER quick-disconnect couplings offer decisive advantages:
