Sterile transfer

Transfer of materials without breaking containment

Transfer of aseptic or toxic products

To support the basic principle of injectable drug production using isolation or barrier technology – separating the  process from the environment – there is a need to transfer materials around the facility as well as in to and out from the filling line without breaking containment and sterility. This may be done to protect the process from the environment (e.g. aseptic production), or to protect the environment from the process (e.g. handling of toxic materials).

The DPTE® transfer system enables the user to introduce material into, or to extract material from a closed barrier, or to connect two devices with identical environments (e.g. isolators) without affecting their ambient characteristics. The DPTE® system is based on the interaction of two separate units – "Alpha" and "Beta" – each fitted with a door, a lock and a sealing function. The Alpha unit is mounted on a support (e.g. an isolator surface), while the Beta unit is movable and seals off a container, a transfer isolator or any other suitable device.

DPTE® Alpha

The core of the DPTE® transfer system is the Alpha port with its secure interlock enabling totally safe connections and disconnections. The DPTE® system enables material to be moved from one sterile zone to another through a non-sterile zone, with leak-tight, risk-free reconnection.
