• AseptiLink™ ST Steam Through Connector

AseptiLink™ ST Steam Through Connector

mdi AseptiLink™ ST steam through connectors are designed to provide safer, secure and validated connection for transfer of sterile fluids. This connector enables integration of steamable hard piped processing systems to gamma sterilized disposable flow paths in single use assemblies.

mdi AseptiLink™ ST, as part of the gamma irradiated single use disposable assembly is connected to stainless steel vessels/piping through its 25mm sanitary flange inlet connection. This connection is steam sterilized, along with SS component of the process flow, effecting a sterile connection between the two.
