Beschrijving
Centrifuge tubes 50 ml PP sterile are conical polypropylene vessels for centrifugation, sample preparation and short-term holding in research and clinical laboratories. Each tube measures 30 x 117 mm and is fitted with a screw cap, while clear graduation markings support straightforward volume assessment during pipetting and dilution. The conical base aids pellet formation and recovery after spinning and fits familiar 50 ml rotor formats. Delivered sterile and autoclavable, the tubes can be used directly from the pack or re-sterilised where protocols permit thermal treatment. A pack of 25 pieces offers a practical working quantity for everyday bench use. These tubes from manufacturer Witeg are made of polypropylene for chemical resistance and mechanical durability under typical laboratory conditions. They suit molecular biology, biochemistry and diagnostic workflows that need secure closure and contamination-controlled consumables. Graduated walls and a reliable screw-cap seal help keep sample integrity from preparation through analysis.

Questions about Centrifuge tubes 50ml PP steril
What is this article?
Centrifuge tubes 50ml PP steril is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Centrifugebuizen (conisch), inside Buizen & flacons, 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.
