Description
Nalgene™ screw closure sets for Oak Ridge tubes provide replacement sealing assemblies sized for 20 mm closures on laboratory centrifuge tubes. The set is built so that even fully filled centrifuge tubes can be run at maximum rated speed when the correct closure is fitted, supporting secure containment during high-speed spins. Construction combines polypropylene with ETFE and fluoroelastomer components, giving a robust multi-material seal suited to demanding centrifugation work. The closures are autoclavable, allowing routine steam sterilisation between uses where laboratory protocols require it. Closure size is 20 mm, and each unit is supplied as a case of two pieces for convenient stocking of spare caps. Offered by manufacturer Thermo Scientific - Laboratory Plastics within the Nalgene™ product line, these screw closure sets are intended for use with equipment and tubes that accept size-20 closures. Gross weight is 0,040 kg per pack, keeping storage and handling straightforward on the bench or in accessory drawers. Choose this set when maintaining Oak Ridge-style tube systems and a reliable, autoclavable 20 mm screw closure is needed for high-speed centrifugation.

Questions about Nalgene™ Centrifuge Tube Sealing Cap Assemblies
What is this article?
Nalgene™ Centrifuge Tube Sealing Cap Assemblies is the article on this page. Luminix Health distributes Thermo Scientific - Laboratory Plastics for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
