Description
Centrifuge tubes 50 ml round bottom BORO are borosilicate glass laboratory tubes intended for centrifugation and sample handling. Each tube offers a 50 ml capacity, a round bottom and a screw cap with GL 25 thread. Overall dimensions are 28 x 140 mm, while the wall thickness is 1,8 mm, giving a sturdy yet practical vessel for routine work. The tubes are ungraduated, so volume checks are performed externally when needed. Supplied as 1 pc with a net weight of 0,045 kg, these centrifuge glasses come from manufacturer Witeg and suit standard laboratory separation tasks. Borosilicate construction provides the chemical resistance and mechanical strength expected of quality lab glassware. The round-bottom geometry supports efficient pellet formation and fits common rotors and adapters designed for this format. Clear glass walls allow continuous visual inspection of contents during processing. The GL 25 screw closure helps keep samples secure during transport and spinning. Together, the defined capacity, wall thickness, dimensions and borosilicate material make these 50 ml round-bottom tubes a reliable choice for research, analytical and quality-control centrifugation workflows.
This article is part of Centrifuge tubes (conical), in Tubes & vials.

Questions about Centrifuge tube, with screw cap, borosi
What is this article?
Centrifuge tube, with screw cap, borosi 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.
