Description
Test tubes 50 ml PP sterile self-standing are conical polypropylene tubes with a free-standing base for convenient bench handling without a rack. Each unit measures 30 x 115 mm, carries graduation markings and closes with a red screw cap for secure sample containment during mixing, storage or light centrifugation steps. Sterile supply and autoclavability support contamination-controlled work and optional re-sterilisation where methods allow. The self-standing conical design simplifies loading, aspiration and pellet recovery while remaining compatible with common laboratory workflows. Packaged as 100 pieces, the format suits higher-throughput preparation and routine sample processing. These tubes from manufacturer Witeg use polypropylene for chemical resistance and mechanical stability in everyday laboratory use. They are appropriate for molecular biology, clinical chemistry and general research applications that benefit from graduated, screw-capped, free-standing 50 ml consumables. Clear volume marks and a coloured cap aid quick identification on the bench.

Questions about Test tubes 50 ml PP sterile self-standing bottom
What is this article?
Test tubes 50 ml PP sterile self-standing bottom is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Centrifuge tubes (conical), inside Tubes & vials, in Labware.
A centrifuge tube is conical so a pellet collects at the tip, and it is rated for a relative centrifugal force. A 15 mL tube and a 50 mL tube are different rotors. Polypropylene is the ordinary plastic. The cap has to survive the same force as the tube.
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.
