Description
Centrifuge tube with conical bottom, 240 ml is a larger-capacity laboratory glass vessel intended for centrifugation and sample handling. Outer diameter is 56 mm and overall height is 147 mm, providing ample working volume for higher sample loads. The conical bottom aids efficient pellet recovery and supernatant removal after spinning. A GL 45 thread together with the matching screw closure cap ensures reliable sealing during use and short-term storage. Constructed from borosilicate glass 3.3, the tube delivers the durability and chemical resistance typical of quality laboratory glassware. This centrifuge glass from manufacturer Rettberg is offered as a single piece and suits research, process-development and analytical laboratories that process larger sample volumes. Nominal volume is 240 ml (0,24 l). Defined dimensions, conical geometry and the GL 45 threaded closure allow straightforward integration into standard laboratory centrifugation and sample-preparation routines where reusable glass tubes are preferred.
This article is part of Centrifuge tubes (conical), in Tubes & vials.

Questions about Centrifuge tube, conical bottom, 240 ml, o-Ø 56 mm, height 147 mm,
What is this article?
Centrifuge tube, conical bottom, 240 ml, o-Ø 56 mm, height 147 mm, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Tubes de centrifugation (coniques), inside Tubes & flacons, in Matériel de laboratoire.
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.
