Steam-Thru Connections

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.

Features Benefits
Innovative three-port design Allows a true steam-through SIP process which eliminates "dead legs" and the need for laminar
flow hoods
Patented valve design Allows sterile connection and disconnection and permits high media flow rate
Thumb latch/Tear-away sleeve Secures valve position, provides visual indicator of process stage
Industry standard terminations Speed connect to the process equipment and connect to popular sizes of flexible tubing
ADCF-free materials Meet BSE/TSE requirements
