Description
Centrifuge tubes with round bottom 10 ml are compact borosilicate glass tubes equipped with a screw cap for reliable sealing under centrifugal force. Measuring 20 × 97 mm with a GL 18 thread and a wall thickness of 1,2 mm, each tube holds a nominal volume of 10 ml and is well suited to small-volume sample preparation, washing steps and density separations. The rounded base distributes stress evenly during high-speed runs and facilitates complete recovery of pellets or precipitates. Manufactured from durable borosilicate glass by Witeg, the tubes combine chemical resistance with good optical clarity for visual monitoring of contents. They are intended for routine use in clinical diagnostics, molecular biology and general laboratory centrifugation where reusable glassware is preferred over single-use plastics. Supplied individually, these round-bottom tubes integrate easily into standard rotor adapters and racks, providing a robust, transparent vessel for aqueous and many organic media throughout daily laboratory workflows.
This article is part of Centrifuge tubes (conical), in Tubes & vials.

Questions about Centrifuge tube round bottom 10 ml
What is this article?
Centrifuge tube round bottom 10 ml 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.
