Nalgene™ Friction-Fit Polypropylene Closures for Plastic Centrifuge

Nalgene™ push-in caps for plastic centrifuge tubes are autoclavable closures intended for round and conical Nalgene centrifuge tubes. Designed for tubes with a 25 mm outer diameter, these push-in caps use a 25 mm closure size and include a pull tab for straightforward removal after centrifugation or storage steps. The caps support routine laboratory workflows where secure sealing of plastic centrifuge tubes is required and where autoclaving forms part of cleaning or reuse cycles. Offered as a case of 20 pieces, they are practical as matching accessories or replacements for compatible Nalgene tube formats. Within the Nalgene™ product line from Thermo Scientific - Laboratory Plastics, the design focuses on simple push-in application combined with controlled opening via the integrated tab. Laboratories handling samples in round or conical plastic centrifuge tubes can use these caps to maintain a consistent closure interface across preparation, spinning, and post-run handling. The 20-piece unit size suits bench stocking for methods that repeatedly call for 25 mm outer-diameter tubes, keeping sealing components aligned with the specified tube geometry without additional adaptation.
