Description
Test tubes PS with PE plugs are polystyrene laboratory test tubes supplied with polyethylene plugs and offered in an 8 ml volume. They sit among laboratory vessels and consumables and are used as test tubes and sample tubes for collecting, holding and transferring samples in daily laboratory practice. Each pack contains 100 pc(s), providing a practical stock for analytical, research and teaching laboratories. The tube is polystyrene (PS) and the plug is polyethylene (PE), giving a PS vessel with a PE closure. Pack weight is 0,368 kg, remaining convenient for shelf storage and movement between rooms. Available from manufacturer SEMADENI, the tubes support general sample handling when an 8 ml plastic test tube with plug is needed. They can be used for aliquoting, grouping of small liquid or solid portions and orderly bench organisation according to in-house methods. The 8 ml capacity suits moderate small-volume work, and the PE plugs allow the tubes to be closed after filling. This PS and PE test-tube combination is packed as 100 pc(s) for regular laboratory supply.

Questions about Test tubes PS with PE plugs, 8 ml
What is this article?
Test tubes PS with PE plugs, 8 ml is the article on this page. Luminix Health distributes SEMADENI 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.
