Description
Flexible stopper for sample tubes with Ø 13 mm in natural colour is a polyethylene laboratory closure for everyday sealing of sample tubes. Produced from polyethylene, the stopper is flexible and conforms to the tube opening, giving a practical fit on tubes of 13 mm diameter. The broader range also includes versions for 16 mm tubes, so laboratories can align stopper size with their tube inventory. The natural-colour finish offers a neutral appearance for general sample handling where strong colour coding is not required, while remaining compatible with coloured variants used elsewhere in the same workflow. Packaged as 1000 pieces with a net weight of 1,000 kg, the stoppers support high-volume laboratory consumption for preparation, holding and internal transfer of samples. From manufacturer Labbox, these ASTIKS-type polyethylene stoppers serve as standard consumables among other laboratory materials. Their flexible design facilitates straightforward placement and removal and helps reduce the risk of accidental leakage during routine tube management. Suitable for research, analytical and teaching environments that rely on 13 mm sample tubes and simple, adaptable closures.

Questions about Flexible stopper for test tubes, for Ø 13 mm tubes, clear
What is this article?
Flexible stopper for test tubes, for Ø 13 mm tubes, clear is the article on this page. Luminix Health distributes Labbox 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.
