Centrifuge tubes 50 ml, 30 x 115 mm, PP are graduated polypropylene vessels for sample handling, storage and centrifugation in routine laboratory work. Each tube provides a 50 ml working volume in a compact 30 x 115 mm format with clear graduation marks that support approximate volume reading during pipetting and dilution. A freestanding skirted base keeps the tube upright on the bench without a separate rack, while the red screw cap gives a secure closure for mixing, transport and spin steps. Supplied non-sterile, they suit workflows that do not require pre-sterilised consumables or that manage asepsis separately. Durable polypropylene (PP) construction offers a practical balance of chemical resistance and mechanical strength under typical lab conditions. From manufacturer Witeg, the tubes are packed in units of 250 pieces for efficient stock replenishment. Standardised 50 ml geometry and outer dimensions help ensure compatibility with many common centrifuge rotors, adapters and storage racks used for this tube class in research, quality-control and teaching environments.
This article is part of Centrifuge tubes (conical), in Tubes & vials.

Questions about Centrifuge tubes 50 ml
What is this article?
Centrifuge tubes 50 ml is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Centrifuge tubes (conical), inside Tubes & vials, in Labmateriaal.
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.
