Description
Flexible stoppers for sample tubes with Ø 16 mm provide a red polyethylene closure that conforms to the tube opening for secure everyday sealing. Made from polyethylene, the flexible design adapts to the mouth of the tube, helping maintain a snug fit during sample handling, short-term storage and transport between laboratory stations. Colour coding in red supports quick visual identification of tube series, reagents or process steps on crowded benches. These stoppers are intended for sample tubes of 16 mm diameter and belong to a range also offered for 13 mm tubes, giving laboratories a consistent closure family across common tube sizes. A pack of 1000 pieces from manufacturer Labbox supplies high-throughput workflows with ample stock for routine use. Net weight is given as 1,000 kg for the pack unit. Suitable for general laboratory sample-tube applications, the flexible polyethylene construction combines practical sealing performance with simple, tool-free placement and removal in daily protocols.

Questions about Flexible stopper for test tubes, for Ø 16 mm tubes, blue
What is this article?
Flexible stopper for test tubes, for Ø 16 mm tubes, blue 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.
