Description
Centrifuge tubes 50 ml PP conical self-standing combine a graduated conical body with a free-standing base for convenient bench handling without a separate rack. Fabricated from polypropylene (PP) and fitted with a screw cap, each tube measures 30 x 115 mm and holds 50 ml. They are autoclavable and temperature-resistant up to 122 °C, supporting sterilisation between uses. Supplied loose in bags in a pack of 50 pieces from manufacturer Witeg, the self-standing design simplifies pipetting, labelling and short-term storage on the work surface. Clear graduations assist approximate volume control during sample preparation, while the conical interior aids pellet recovery after centrifugation. Typical laboratory applications include cell culture work-up, buffer and media aliquots, precipitation protocols, extraction steps and general molecular or biochemical sample processing. Polypropylene construction offers practical chemical resistance for many routine aqueous reagents. These self-standing 50 ml conical tubes fit standard laboratory workflows that require secure closure, thermal durability and stable upright positioning during multi-step procedures.

Questions about Centrifuge tubes with screw cap made of PP
What is this article?
Centrifuge tubes with screw cap made of PP 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.
