Create aseptic handling solutions for pharmaceutical, biotechnology and laboratory liquid transfer applications with Thermo Scientific™ Nalgene™ Top Works™ Flexible Systems for Nalgene Bottles, Carboys and Media. Modified closures included platinum-cured silicone stopper inserts and tubing. These leakproof systems offer more secure, aseptic handling of high-valued products compared to pouring, and they are available with various ports, tubing lengths and closure sizes.

Securely close off 3/4 in. or 3 in. sanitary ports on carboys with Thermo Scientific™ Nalgene™ Polypropylene End Caps. These are reliable, repeatable seals when used in combination with a silicone gasket and true union clamp.  A groove on underside of end cap accepts standard sanitary gaskets for sealing the systems.
