Description
Screw-cap tubes with PP closure and flat bottom (Ø 20 x 150 mm) are borosilicate glass laboratory tubes designed for sample collection, storage and general laboratory processing. They carry a 15-415 screw thread and are fitted with a neutral polypropylene closure with PTFE seal for dependable sealing against many laboratory chemicals. Manufacturer information also lists an alternative black phenolic resin cap with silicone seal, so users can match the closure to their application. The larger 20 mm diameter provides greater working volume than narrower formats while the flat bottom ensures stable placement on benches and in tube racks. Borosilicate glass delivers the thermal and chemical durability expected in everyday lab work, and the tubes are autoclavable for standard sterilisation cycles. Supplied by manufacturer Labbox in packs of 100 pieces, these tubes suit chemistry, life-science and QC environments that need robust screw-cap glassware with consistent geometry for aliquoting, incubation and short- to medium-term sample holding.
This article is part of Test tubes, in Tubes & vials.

Questions about Test tubes with PP screw cap, flat bottom, Ø20 x 150, 100 pcs
What is this article?
Test tubes with PP screw cap, flat bottom, Ø20 x 150, 100 pcs is the article on this page. Luminix Health distributes Labbox 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.
