Description
Centrifuge tube with round bottom, 80 ml is a laboratory glass vessel for sample separation by centrifugation. Made from borosilicate glass 3.3, it provides chemical resistance and thermal stability for routine analytical and preparative work. The tube has an outer diameter of 40 mm and a height of 115 mm, giving a nominal volume of 80 ml (0,08 l). Its round-bottom geometry supports efficient sedimentation and straightforward pellet recovery. Offered as a single piece from manufacturer Rettberg and originating in Germany, the tube matches the dimensional needs of many standard laboratory centrifuge rotors. The clear borosilicate glass 3.3 wall permits easy visual inspection of contents during processing. This 80 ml round-bottom centrifuge tube is suited to biochemistry, clinical and general research laboratories that prefer durable glassware for separation steps. Defined outer diameter, height and volume help ensure consistent handling and reproducible results in everyday centrifugation workflows where robust glass construction is required.
This article is part of Centrifuge tubes (conical), in Tubes & vials.

Questions about Centrifuge tube, round bottom, 80 ml o-Ø 40 mm, height 115 mm
What is this article?
Centrifuge tube, round bottom, 80 ml o-Ø 40 mm, height 115 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.
