Description
Graduated centrifuge tubes with a nominal volume of 20 ml serve as practical vessels for medium-scale laboratory centrifugation and sample work-up. These round-bottom, thick-walled tubes have an outer diameter of 24 mm and a height of 98 mm, fitting rotors that accept this common size range. Permanent graduation marks allow convenient volume reading, and the screw cap provides dependable sealing during spinning, mixing or temporary storage. Supplied individually, they offer a straightforward solution for daily preparative tasks. Made by Witeg, the tubes combine mechanical resilience with clear visibility of contents. The heavy-wall design supports repeated use under standard centrifugal loads, while the round bottom promotes smooth resuspension of sediments. Appropriate for research, quality-control and teaching laboratories, these graduated glass tubes facilitate efficient handling of intermediate sample volumes within established centrifugation routines.

Questions about Centrifuge tubes 25 ml 24 x 98 mm graduated
What is this article?
Centrifuge tubes 25 ml 24 x 98 mm graduated is the article on this page. Luminix Health distributes Witeg 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.
