Description
Nalgene™ PPCO round-bottom centrifuge tubes for high-speed applications are laboratory centrifuge tubes designed for demanding separation work. Constructed from polypropylene copolymer (PPCO), they offer uniform wall thickness and diameter that improve rotor fit and overall performance under high centrifugal forces. The tubes have a nominal volume of 12 ml, a round-bottom shape, and are rated to a maximum force of 50 000 × g. They are autoclavable, supplied without graduations and without a writing area, and are packed as a case of 100 pieces (10 per inner pack). These tubes from manufacturer Thermo Scientific – Laboratory Plastics are intended for high-speed centrifugation protocols in research and industrial laboratories where consistent geometry and mechanical strength are required. The PPCO material provides the necessary chemical resistance and durability for repeated autoclaving cycles while maintaining dimensional stability during high-g runs. Ideal for pelleting, density-gradient work and other high-speed applications that benefit from round-bottom geometry.
This article is part of Centrifuge tubes (conical), in Tubes & vials.

Questions about Nalgene™ High-Speed Round-Bottom PPCO Centrifuge Tubes
What is this article?
Nalgene™ High-Speed Round-Bottom PPCO Centrifuge Tubes is the article on this page. Luminix Health distributes Thermo Scientific - Laboratory Plastics 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.
