Description
Test tube with screw cap and phenolic resin cap, round bottom, Ø13 is a borosilicate glass laboratory tube for sample handling, storage and routine analytical work. The round-bottom format with a 15-415 screw thread provides a stable vessel that can be closed securely during processing and transport. Caps are available as a black phenolic resin closure with silicone seal (type A) or as a neutral polypropylene closure with PTFE seal (type B), so the seal material can be matched to chemical compatibility needs. The tubes are autoclavable and therefore suitable for standard laboratory sterilisation cycles. Supplied in a pack of 250 pieces with a net weight of 1,060 kg from manufacturer Labbox, they support workflows in chemistry, life sciences and clinical sample preparation where durable glassware and resealable closures are required. Borosilicate construction, round-bottom geometry and interchangeable phenolic or polypropylene caps with silicone or PTFE seals make these tubes practical for heating, mixing and short- to medium-term sample retention under controlled laboratory conditions.
This article is part of Test tubes, in Tubes & vials.

Questions about Test tubes with phenolic screw cap, round bottom, Ø13 x 100, 250 pcs
What is this article?
Test tubes with phenolic screw cap, round bottom, Ø13 x 100, 250 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.
