Description
Centrifuge tube with round bottom, 25 ml, is a laboratory glassware item intended for centrifugation of liquid samples in research and analytical settings. It has an outer diameter of 24 mm and a height of 100 mm, providing a practical format that fits standard rotors and tube racks. Made from borosilicate glass 3.3, the tube combines chemical resistance with good thermal stability for repeated laboratory use. The round-bottom profile aids efficient pellet formation and straightforward recovery or resuspension of sediments after spinning. Supplied as 1 pc, this centrifuge tube from manufacturer Rettberg supports routine workflows in cell biology, biochemistry, clinical sample preparation and general analytical chemistry. Optical clarity of the glass allows easy visual inspection of contents, while the precise dimensions ensure consistent handling and storage. Researchers rely on such tubes for sedimentation, simple concentration steps and density-related separations where dimensional accuracy and material integrity matter. The combination of 25 ml nominal volume, 24 mm diameter and 100 mm height makes it a practical choice for everyday centrifugation tasks requiring durable glass construction.
This article is part of Centrifuge tubes (conical), in Tubes & vials.

Questions about Centrifuge tube, round bottom, 25 ml o-Ø 24 mm, height 100 mm
What is this article?
Centrifuge tube, round bottom, 25 ml o-Ø 24 mm, height 100 mm is the article on this page. Luminix Health distributes Rettberg 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.
