Description
Nalgene™ push-in caps for plastic centrifuge tubes are dedicated closures designed for secure sealing of laboratory centrifuge tubes during routine sample handling. Intended for round and conical Nalgene centrifuge tubes with a 32 mm outer diameter, these caps provide a practical push-in fit matched to that closure size. Each cap is equipped with a pull tab that supports straightforward removal after use, helping maintain efficient workflow in the laboratory. The closures are autoclavable, supporting standard sterilisation practice where heat processing of plastic labware is required. Supplied as a case of 20 pieces (20 per pack and 20 per carton), the set is suited to laboratories that process multiple tubes in parallel and need consistent replacement caps. These Nalgene™ centrifuge tube caps from manufacturer Thermo Scientific - Laboratory Plastics complement plastic centrifuge tube systems used in sample preparation, separation, and general benchtop centrifugation. With a gross weight of 0,045 kg per unit pack, they are a compact accessory option within centrifuge tube consumables for research and analytical environments that rely on Nalgene plasticware.

Questions about Nalgene™ Friction-Fit Polypropylene Closures for Plastic Centrifuge
What is this article?
Nalgene™ Friction-Fit Polypropylene Closures for Plastic Centrifuge 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.
