Description
Test tube with screw cap and phenolic resin cap, flat bottom, is a borosilicate glass laboratory tube designed for routine sample handling, storage and general wet-chemistry work. It features a 15-415 screw thread and is supplied with a black phenolic resin closure fitted with a silicone seal, providing a reliable seal for aqueous and many organic media. The flat-bottom geometry allows the tube to stand stably on the bench or in racks without additional supports, which is practical during multi-step preparations and short-term incubations. Manufactured by Labbox, the tube is autoclavable, supporting standard steam-sterilisation cycles between uses when laboratory protocols require reusable glassware. The phenolic resin cap with silicone gasket is intended for applications where a robust, chemically resistant closure is preferred. Packaged as 100 pc(s), this format suits teaching laboratories, quality-control benches and research groups that need a consistent supply of screw-cap tubes. Net weight of the pack is 2,875 kg. Suitable for sample collection, reagent aliquoting and intermediate storage in analytical and life-science workflows where borosilicate glass and a phenolic screw closure are specified.
This article is part of Test tubes, in Tubes & vials.

Questions about Test tubes with phenolic screw cap, flat bottom, Ø20 x 150, 100 pcs
What is this article?
Test tubes with phenolic 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.
