Description
Flexible stopper for sample tubes with Ø 16 mm is a polyethylene closure designed to seal laboratory sample tubes securely during handling, storage and transport. The green stopper is flexible and conforms to the tube opening, helping to reduce leakage and evaporation while remaining easy to fit and remove in routine workflows. Manufactured from polyethylene, it offers a practical, durable seal for everyday sample preparation and short-term holding of liquids or suspensions in clinical, research and teaching laboratories. This variant is intended specifically for tubes with a 16 mm diameter; matching flexible stoppers are also offered for 13 mm tubes within the same product family. Supplied in a pack of 1000 pieces with a net weight of 1,000 kg, the stoppers support high-throughput bench work and bulk replenishment of consumable stocks. From manufacturer Labbox, these green polyethylene stoppers provide a straightforward colour-coded option for organising sample series, distinguishing process steps or marking tube sets without complicating standard laboratory procedures.

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