Description
PE stopper for centrifuge tubes Cat. No. 115350 is a dedicated laboratory closure made from low-density polyethylene (LDPE). It is intended for use with polypropylene (PP) centrifuge tubes that have a nominal volume of 48 ml, providing a secure fit that helps retain samples during centrifugation, transport and short-term storage. The flexible LDPE construction allows straightforward insertion and removal while offering the chemical resistance expected in routine laboratory work. Packaged as 100 pieces, the stoppers support efficient stocking for high-throughput environments such as research, clinical and industrial laboratories. This accessory from manufacturer Brand integrates easily into existing sample-preparation workflows without requiring special adapters. Non-sterile by design, the stoppers are suitable for general laboratory applications where aseptic conditions are not mandatory. With a net pack weight of 0,445 kg they remain convenient to handle and store. Laboratories working with the matching 48 ml PP tubes benefit from a purpose-matched seal that reduces the risk of leakage and cross-contamination during everyday procedures.

Questions about Stopper, PE, for centrifuge tubes art.-no. 1153 50
What is this article?
Stopper, PE, for centrifuge tubes art.-no. 1153 50 is the article on this page. Luminix Health distributes Brand for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Labware.
A rubber or silicone stopper is pushed into a mouth. The size number corresponds to a top and bottom diameter. Silicone survives higher temperatures and more autoclave cycles. Natural rubber is attacked by oils and by some solvents.
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.
