Opta® SFT Aseptic Tube Connectors

Opta® SFT Aseptic Tube Connectors

Connect with Simplicity, Flexibility and Reliability

Biopharmaceutical processes demand fast, reliable and sterile connections for fluid transfer. The Opta® SFT single-use connector is designed to form a sterile connection between two pre-sterilized components. Quick and easy to use, Opta® connectors are extensively validated and backed by 100% in-house integrity testing. The Opta® SFT is available as a standalone component for end-user assembly with silicone or TPE tubing or can be pre-designed into a single-use assembly.

Opta® SFT Aseptic Connectors

Biopharmaceutical operations at small and large scale depend on secure sterile connections for transferring fluids. Opta® SFT aseptic connectors are easy to use, adaptable for hybrid and single-use operations, and backed by validation testing and quality assurance. The simple 3-click operation ensures consistent results with every use.

6 Steps and 3 Clicks to Aseptic Connection

With Opta® SFT connectors, operators perform 6 steps, signaled by 3 clicks, to assure consistent aseptic connections every time.

Step 1

Remove protective caps by pulling on the bottom flaps.
Retract the collar that is fixed on the female connector to prepare for assembly.

Step 2

Slide male and female connectors together until the two pins of the male connector “click”  into place.

Step 3

Join the grippers at the bottom of each membrane tape together. The grippers should also “click”  into place.

Step 4

Holding the grippers perpendicular to the connector bodies, rotate the device 90° so the membrane is in the horizontal position.

Step 5

With the handle in one hand, gently remove the membrane horizontally with the other hand.

Step 6

Slide the collar that has been retracted back in place and turn it clockwise until the lock “clicks”  into place.
