Description
Nalgene™ Oak Ridge polysulfone centrifuge tubes with screw caps are robust, transparent vessels engineered for high-speed centrifugation of laboratory samples. Each tube holds a nominal volume of 50 ml and is moulded from polysulfone (PSF/PSU), delivering excellent clarity so contents remain clearly visible. The polypropylene screw caps provide a secure seal; when used with sealing caps the tubes withstand forces up to 50 000 × g. Round-bottom geometry ensures compatibility with standard rotors, while the material permits repeated autoclaving for sterile workflows. Graduations are absent and no writing area is provided, keeping the outer surface smooth. Packaged as 10 tubes per pack and 100 tubes per case, the set suits high-throughput sample processing in molecular biology, biochemistry and clinical research. These centrifuge tubes from manufacturer Thermo Scientific combine chemical resistance, thermal stability and optical transparency, making them a reliable choice for demanding separation protocols that require both visibility and mechanical strength under elevated g-forces.
This article is part of Centrifuge tubes (conical), in Tubes & vials.

Questions about Nalgene™ Oak Ridge Polysulfone Centrifuge Tubes w/Screw Caps
What is this article?
Nalgene™ Oak Ridge Polysulfone Centrifuge Tubes w/Screw Caps 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.
