Maintain the integrity of a container and its contents with Thermo Scientific™ Nalgene™ Quick Filling/Venting Closures. A convenient fluid transfer system, this ported 83B closure features a quick-disconnect fitting with tubulation for attachment to tubing of your choice. Fittings have tubulation both in and outside of the closure, and socket fittings in the cap have internal valves that seal when a tubulation fitting is removed to maintain container seal integrity.

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.

Use Thermo Scientific™ Nalgene™ Spigot Closure with Polypropylene Lock Nut and TPE Plug in place of a spigot when autoclaving liquids in a Nalgene carboy to provide a leakproof† seal. This closure is also useful when handling could damage or accidentally turn on a spigot, or when a spigot-less carboy is required. Fits all Nalgene carboys with spigot and selected Nalgene tanks with spigot.

Protect against leakage, breakage and contamination by using Thermo Scientific™ Nalgene™ Silicone Sanitary Gaskets for Nalgene™ Carboys. Constructed of platinum-cured silicone, the gaskets ensure the highest degree of purity for biopharmaceutical applications.
