Description
Centrifuge tube with round bottom, 23 ml, is a laboratory glass vessel with an outer diameter of 24 mm and a height of 100 mm. It is made from borosilicate glass 3.3 and fitted with a GL 25 thread together with a matching screw cap for secure closure. The round-bottom design facilitates efficient sedimentation and easy recovery of pellets or precipitates after centrifugation. Available as a single piece, this tube from manufacturer Rettberg supports sample preparation, separation and intermediate storage in research, analytical and quality-control environments. Borosilicate glass 3.3 provides the chemical resistance and thermal stability needed for routine aqueous and many organic media. The 23 ml nominal volume accommodates larger aliquots than smaller tubes of the same series, while the 24 mm outer diameter and 100 mm length ensure fit in rotors and adapters intended for this format. The GL 25 screw closure permits rapid, tool-free opening and resealing, helping preserve sample integrity between steps. This centrifuge tube offers a durable, reusable glass option for medium-volume laboratory centrifugation work.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Centrifuge tube, round bottom, 23 ml, o-Ø 24 mm, height 100 mm,
What is this article?
Centrifuge tube, round bottom, 23 ml, o-Ø 24 mm, height 100 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.
