Steam-Thru® Connections allow a quick and easy sterile connection between biopharmaceutical processing equipment and disposable bag and tube assemblies. The single-use design saves time and money by eliminating unnecessary cleaning procedures and reducing validation burden associated with reusable components.

The innovative three port design of CPC’s Steam-Thru® technology enables uncomplicated actuation between the SIP steam pathway and fluid transfer (flow) pathway. This provides an easy and sterile connection between flexible single-use tubing and stainless-steel processing equipment. The Steam Thru product lines offer versatility within your process by having connection options for 3/8” and 1/2" ID tubing on the single-use side of the connector and 3/4" and 1-1/2" sanitary connections for attachment to the stainless-steel processing equipment.

Features and Benefits

Three port design allows a true steam-through SIP process which eliminates dead legs and the need for laminar flow hood. 
Patented valve design allows sterile connection and disconnection and permits high media flow rate

Steam-Thru II Connections offer the flexibility of "steam on" and "steam off" functionality. The innovative design allows the valve to be returned to the steam position enabling a second SIP cycle following media transfer. The "steam off" disconnection of single-use systems minimizes cross-contamination risks associated with reusable components.

Applications

Bioreactor Feeding
Cell Harvesting 
Product Sampling
Media Transfer 
Single-Use Bag Systems
