Description
The centrifuge tube 85 ml 115 x 40 mm round bottom is a thick-walled laboratory glass vessel designed for dependable performance in centrifugal separations. Fabricated from DURAN tubing, it presents a round bottom, rimless finish and ungraduated walls that allow continuous visual observation of the sample throughout processing. Measuring 115 x 40 mm with an 85 ml capacity, the tube accommodates intermediate volumes while maintaining the mechanical integrity required for standard laboratory rotors. The heavy-wall construction enhances safety under load, and the lack of a rim simplifies placement into adapters and carriers. This centrifuge glass tube from manufacturer Witeg is offered as a single piece and suits research, clinical and industrial laboratories that need chemically resistant, optically clear glassware without volume markings. Common applications include cell pelleting, protein recovery, nanoparticle isolation, density-gradient fractionation and general sample concentration steps. With a net weight of 0,09 kg the unit remains easy to handle and store on the laboratory bench.
This article is part of Centrifuge tubes (conical), in Tubes & vials.

Questions about Centrifuge tubes 85 ml
What is this article?
Centrifuge tubes 85 ml 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.
