Description
Centrifuge tubes PP 7 ml 12 x 100 mm are cylindrical polypropylene sample tubes for routine laboratory centrifugation and aliquot handling. Each tube is made of transparent PP, offers a nominal volume of 7 ml and measures 12 x 100 mm, with a round bottom that seats cleanly in matching rotors and racks. The clear wall allows straightforward visual checks of fill level, phase separation and pellet formation during preparation and spin steps. Supplied in packs of 100 pieces, the format suits daily workflows in research, analytical and teaching laboratories where disposable plasticware is preferred for sample and reagent vessels. Polypropylene provides useful chemical resistance for many aqueous buffers and common laboratory media. These centrifuge tubes from manufacturer Witeg combine a simple cylindrical profile with a round bottom for stable placement during mixing, storage and short-term holding of intermediate fractions. Net pack weight is 0,343 kg. They support organised processing of clinical, academic and industrial samples whenever a compact 7 ml PP tube in the 12 x 100 mm size is required.
This article is part of Centrifuge tubes (conical), in Tubes & vials.

Questions about Centrifuge tube PP 7ml 12x100mm
What is this article?
Centrifuge tube PP 7ml 12x100mm 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.
