Centrifuge tube with conical bottom, 75 ml is a larger-capacity laboratory glass tube measuring 40 mm outer diameter and 115 mm in height. Constructed from borosilicate glass 3.3, it offers reliable chemical durability and thermal performance for centrifugation procedures. The conical base assists complete sediment collection, while the GL 32 thread and matching screw cap provide a secure seal throughout processing. Offered as one piece, the vessel handles its full nominal volume and matches rotors and adapters intended for glass tubes of this size. Manufactured by Rettberg, the tube is suited to biochemistry, diagnostic and general research settings that demand consistent separation of suspensions. Clear glass walls enable easy inspection of sample layers and pellets. The solid build withstands routine laboratory handling and cleaning cycles. Its defined geometry ensures compatibility with standard centrifuge equipment used for higher-volume sample preparation.
This article is part of Centrifuge tubes (conical), in Tubes & vials.

Questions about Centrifuge tube, conical bottom, 75 ml, o-Ø 40 mm, height 115 mm,
What is this article?
Centrifuge tube, conical bottom, 75 ml, o-Ø 40 mm, height 115 mm, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Centrifugebuizen (conisch), inside Buizen & flacons, in Labmateriaal.
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.
