Description
Test tubes 15 ml cylindrical with screw cap are polystyrene (PS) vessels intended for sample collection, reagent preparation and everyday laboratory handling. The cylindrical body holds a nominal 15 ml working volume and measures 16 × 120 mm, providing a familiar footprint for racks, rotors and storage systems designed around this size. A screw closure enables reliable sealing for mixing, transport and temporary storage, limiting leakage and evaporation during routine procedures. The clear PS construction supports visual inspection of fill level, colour and phase separation, which is useful in analytical, clinical-support and teaching environments. Each pack contains 750 pieces, supporting continuous use in high-volume workflows without frequent reordering. These tubes from manufacturer Witeg serve as practical sample tubes, reagent tubes or general-purpose containers wherever a non-sterile 15 ml cylindrical screw-cap format is required. Their light weight and consistent geometry simplify handling, labelling and organisation across multi-step protocols. Select this pack when a durable PS tube with screw closure and standard 16 × 120 mm dimensions is needed for day-to-day laboratory operations.
This article is part of Test tubes, in Tubes & vials.

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 Test tubes, inside Tubes & vials, in Labware.
A test tube is the open cylindrical vessel for a small liquid, in borosilicate glass or in plastic. Rimmed and rimless mouths differ. The size is diameter by length. It is not graduated for a result, and a glass tube that will be centrifuged has a force limit.
A tube holds a small sample upright. A test tube is the open glass or plastic cylinder. A centrifuge tube is conical so a pellet forms at the tip, and it is rated for a centrifugal force the rotor will actually reach. A vial is a small closed bottle, often for a sample that will sit in an instrument. NMR tubes are a special case: the glass has to be uniform or the spectrum is the tube, not the sample. Laboratory ware is listed under ISO laboratory glassware.
