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 Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

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 Round-bottom flasks, inside Beakers & flasks, in Labware.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
