Description
Flexible stoppers for sample tubes with Ø 16 mm offer a blue polyethylene closure that adapts to the tube opening for dependable laboratory sealing. Fabricated from polyethylene, the flexible stopper conforms to the mouth of the tube, supporting secure closure during sample handling, interim storage and movement between work areas. The blue colour enables straightforward visual coding of tube batches, media types or process stages alongside other coloured stoppers. Sized for tubes of 16 mm diameter, the product sits within a family also available for 13 mm tubes, allowing laboratories to standardise flexible polyethylene stoppers across frequent tube formats. Delivered as a pack of 1000 pieces from manufacturer Labbox, the stoppers suit high-volume sample-tube workflows that require ready bulk supply. Net weight is specified as 1,000 kg for the pack unit. Ideal for general laboratory use with sample and reagent tubes, the flexible design combines easy insertion and removal with a practical seal for routine bench procedures.

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