Colder Products Company Steam-Thru® connection allows quick and easy SIP sterilization between stainless steel biopharmeceutical processing equipment and disposable bag and tubing assemblies


Steam-Thru Connections allow a quick and easy sterile connection via SIP between stainless steel biopharmaceutical processing equipment and disposable bag and tube assemblies.

The single-use design saves time and money by eliminating unnecessary cleaning procedures and reducing the burden associated with the validation of reusable components.

  • 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 and provides visual indicator of process stage
  • Industry standard terminations provide for speedy connection to the process equipment and connection to popular sizes of flexible tubing
  • ADCF-free materials meet BSE/TSE requirements
