QUICKSEAL® is an intuitive, simple-to-use and reliable aseptic disconnect and closure in one.

QUICKSEAL® aseptic disconnect makes critical fluid-management easy, efficient and reliable. QUICKSEAL® securely seals and disconnects tubing after sampling or inoculation, media and buffer feeds, product transfer or any critical fluid-handling process.

The principle behind the surprisingly simple and amazingly robust QUICKSEAL® is easy to understand:

Simply cut the metal collar with our hand-held QUICKSEAL® tools. The cutting action deforms the aluminum collar squeezing the tube and compressing tubing wall together creating an aseptic seal. Sealing time is less than 4 seconds.

Robust and Secure

  • Validated microbial barrier. Cut collar passes microbial ingress testing by container closure
  • Closure integrity verified at ambient temperatures and after freeze|thaw cycle to -100° Celsius
  • Burst testing proves pressure resistance of cut collar exceeds burst pressure of tubing
