AseptiQuik STC

See AseptiQuik STC Connector Products

AseptiQuik® STC Connectors integrate the AseptiQuik sterile connector and the Steam-Thru® II SIP connector, giving manufacturers flexibility between hybrid stainless steel and single-use processing equipment. The AseptiQuik STC connector combines either an AseptiQuik G, AseptiQuik S or AseptiQuik C sterile connector with a Steam-Thru II connection that can be mounted directly to stainless steel processing equipment via a sanitary termination. AseptiQuik STC connectors utilizing an AseptiQuik G or S sterile connector offer a genderless design, simplifying system integration at the aseptic connector end. AseptiQuik STC connectors utilizing an AseptiQuik C sterile connector allow system designers to incorporate a keyed female-to-male connection at the aseptic connector end.

The union of the two connectors into a single unit through a sanitary clamp allows an AseptiQuik sterile connection to be steamed on to stainless equipment via SIP. After the SIP cycle, a wide range of single-use systems can be connected. The SIP process can be done in advance allowing a quick and easy sterile connection to the AseptiQuik half without having to wait 30-60 minutes for SIP prior to harvest.
