Description
PTFE test tube with conical bottom and 18 ml capacity is a thick-walled laboratory vessel made from polytetrafluoroethylene with a smoothed inner surface. The material is chemically inert and remains usable up to 280 °C, supporting work with aggressive reagents and elevated thermal loads where glass is less suitable. The conical base aids collection of residual liquid and quantitative transfer of small sample volumes. Supplied as a single piece from manufacturer Labbox, this tube fits routine analytical, preparative and quality-control workflows that require an inert, non-adherent contact surface. Net weight is 0,019 kg. Thick walls improve mechanical stability during handling and thermal cycling, while the PTFE surface reduces residue build-up and simplifies cleaning after use. Typical placements include digestion steps, intermediate sample holding and storage of corrosive media in test-tube and sample-tube applications across wet-chemistry laboratories.
This article is part of Test tubes, in Tubes & vials.

Questions about Test tube, PTFE, conical bottom, 50 ml
What is this article?
Test tube, PTFE, conical bottom, 50 ml 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.
