Description
Centrifuge tube with conical bottom, 23 ml, O.D. 24 mm, height 100 mm is a versatile laboratory glass vessel designed for medium-volume centrifugation tasks. Constructed from borosilicate glass 3.3, it features a nominal volume of 23 ml, an outer diameter of 24 mm and a height of 100 mm. The conical bottom geometry aids efficient sediment collection and subsequent resuspension of pellets. It incorporates a ground joint sleeve NS 19/17 paired with a hollow stopper that provides a dependable seal throughout spinning and interim storage. This centrifuge tube from manufacturer Rettberg unites accurate dimensions with the proven chemical resistance and thermal performance of borosilicate glass 3.3, making it suitable for chemistry, life-science and clinical laboratory applications. The standardised joint permits ready integration with complementary glass apparatus, while the hollow stopper simplifies routine handling. Supplied as a single piece, the tube supports a broad spectrum of separation methods that demand optical transparency, mechanical robustness and material inertness. Its durable build tolerates standard laboratory washing and autoclaving procedures, ensuring reliable service over extended use.

What is this article?
Centrifuge tube, conical bottom, 23 ml, o-Ø 24 mm, height 100 mm, with 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.
