Description
Centrifuge tube with round bottom, 50 ml, is a laboratory glassware item intended for centrifugation of liquid samples in research and analytical settings. It has an outer diameter of 34 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 50 ml nominal volume, 34 mm diameter and 100 mm height makes it a practical choice for everyday centrifugation tasks requiring durable glass construction.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Centrifuge tube, round bottom, 50 ml o-Ø 34 mm, height 100 mm
What is this article?
Centrifuge tube, round bottom, 50 ml o-Ø 34 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.
