Description
Nalgene™ push-in caps for plastic centrifuge tubes are autoclavable closures made for round and conical Nalgene centrifuge tubes. Sized for tubes with a 29 mm outer diameter, these push-in caps provide a 29 mm closure and feature a pull tab that simplifies removal after use. They suit laboratory centrifugation and sample-handling steps where plastic tubes must be sealed securely and where autoclaving is part of the cleaning or reuse routine. Supplied as a case of 20 pieces, the caps serve as matching accessories or spare closures for compatible Nalgene tube formats. As part of the Nalgene™ range from Thermo Scientific - Laboratory Plastics, they combine a straightforward push-in fit with controlled opening via the integrated tab. Research, analytical, and quality-control laboratories working with round or conical plastic centrifuge tubes can rely on this closure geometry to keep sealing consistent across preparation, spin, and post-run handling. The 20-piece pack supports convenient bench stocking for methods that specify 29 mm outer-diameter tubes, helping keep consumable closures aligned with the intended tube dimensions.

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 Vial caps & septa, inside Vials, caps & septa, in Chromatography equipment.
A vial cap and a septum have to match the vial neck: crimp, screw or snap, and the diameter. The septum material, PTFE/silicone or rubber, decides chemical resistance and how many times a needle can pierce it. A septum that sheds into the solvent becomes ghost peaks.
An autosampler vial is the small closed bottle a chromatograph picks up. The neck is crimp, screw or snap, and the cap and the septum have to be that neck. The septum is the part the needle pierces. A soft septum reseals. A septum that is wrong for the solvent swells or sheds particles into the sample. Inserts reduce the volume when the sample is scarce. The separation they feed is described with IUPAC names and PubChem data.
