Description
Test tubes with screw cap and phenolic resin closure are round-bottom borosilicate glass tubes for general laboratory sample handling, reagent work and storage. Each tube is fitted with a 15-415 thread and is available with a black phenolic resin cap with silicone seal or with a neutral polypropylene cap with PTFE seal, giving flexibility for different chemical compatibility needs. The glass construction supports clear visual inspection of contents, while the screw-thread design helps secure samples during transport and short-term holding. These tubes are autoclavable, so they can be integrated into sterilisation routines where heat-stable glassware is required. Supplied in a pack of 250 pieces from manufacturer Labbox, they suit routine bench work in chemistry, biology and quality-control laboratories that need reliable screw-cap tubes without complex preparation. The round-bottom profile and Ø12 format fit standard racks and handling practices for small-volume samples. Choose the phenolic or polypropylene closure option according to seal preference and method requirements for everyday laboratory workflows.

Questions about Test tubes with phenolic screw cap, round bottom, Ø12 x 75, 250 pcs
What is this article?
Test tubes with phenolic screw cap, round bottom, Ø12 x 75, 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.
