Description
Test tubes 15 ml cylindrical with screw cap are sterile polystyrene (PS) laboratory tubes for sample handling, reagent work and general analytical tasks that benefit from a ready-to-use clean vessel. Each tube provides a nominal 15 ml capacity in a cylindrical body of 16 × 120 mm, matching common rack and centrifuge formats used in research, quality control and teaching laboratories. The screw closure offers secure sealing during mixing, short-term storage and transport, helping to protect contents from spillage and evaporation. Sterile supply reduces preparation time when aseptic or low-contamination conditions are preferred. A pack of 700 pieces supports efficient stocking for series work and multi-user environments. Produced by Witeg, these PS tubes combine optical clarity for visual checks with the mechanical stability expected of standard disposable sample and reagent tubes. Their cylindrical profile aids consistent labelling and organised storage. Deploy them wherever a sterile 15 ml screw-cap cylindrical tube is specified for routine sample processing, aliquoting or intermediate holding of laboratory media and specimens.

Questions about Test tubes 15ml cylindrical screw cap
What is this article?
Test tubes 15ml cylindrical screw cap is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
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.
