Description
Nalgene™ screw closure set for Oak Ridge tubes is a centrifuge bottle sealing cap assembly prepared for selected large-format Nalgene vessels. It is intended for use with specific 250 ml and 290 ml Nalgene centrifuge bottles, including formats referenced as 3120-0250, 3122-0250, 3123-0250 and 3127-0250, where a dedicated sealing closure is required. The assembly uses polypropylene together with ETFE and fluoroelastomer to form a sealing cap suited to centrifuge bottle duty. The closure is autoclavable, supporting sterilisation cycles when laboratory procedures call for reusable, heat-tolerant hardware. Each pack contains two pieces (case of 2), giving a compact spare set for bottle lines that share the same sealing geometry. From manufacturer Thermo Scientific - Laboratory Plastics, this Nalgene™ closure type is positioned as a sealing cap for centrifuge bottles rather than a general tube lid. Gross weight is 0,068 kg. Select this screw closure set when operating 250 ml and 290 ml Nalgene centrifuge bottles that need a matching polypropylene–ETFE–fluoroelastomer sealing assembly for secure, autoclavable performance in the centrifuge.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Nalgene™ Centrifuge Bottle Sealing Cap Assembly
What is this article?
Nalgene™ Centrifuge Bottle Sealing Cap Assembly 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.
