Description
PTFE test tube with round bottom and 17 ml capacity is a thick-walled laboratory vessel made from PTFE with a smoothed inner surface for clean sample contact. Chemically inert and usable up to 280 °C, it suits demanding handling of aggressive media where glass may be unsuitable. The round-bottom geometry supports even heating and mixing in small-scale reaction, digestion, or sample-preparation workflows, while the PTFE body resists a wide range of chemicals common in analytical and research laboratories. Supplied as a single piece with a net weight of 0,018 kg, the tube is easy to integrate into existing racks and heating setups designed for compact vessels. Labbox manufactures this PTFE test tube for users who need durable, inert sample containment at elevated temperature. Thick walls add mechanical robustness during repeated use, and the smoothed interior helps reduce hold-up and simplifies cleaning between runs. Ideal for laboratories working with corrosive reagents, high-purity samples, or temperature-sensitive protocols that still require thermal stability up to 280 °C. Choose the 17 ml round-bottom PTFE format when chemical inertness and heat resistance are essential for reliable tube-scale work.

Questions about Test tube, PTFE, round bottom, 17 ml
What is this article?
Test tube, PTFE, round bottom, 17 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.
