Description
Screw cap tubes in brown polypropylene are conical vessels with a 2,0 ml capacity for laboratory sample processing and storage. Produced from PP, the brown tubes assist in protecting light-sensitive samples during molecular biology, microbiology and cell-culture work. The conical base promotes efficient concentration and recovery of pellets after centrifugation or settling, and the screw-cap design enables secure closure with matching lids. Available as a pack of 1000 pc(s) from manufacturer ROTH SELECTION, they address routine needs for screw-in vessels and cryogenic-style tube systems in busy laboratories. Polypropylene construction offers the chemical resistance associated with standard PP labware, while the 2,0 ml volume covers common aliquot and extract sizes. Brown colouring supports rapid identification beside clear tubes on the bench. With a pack weight of 1,210 kg, the bulk quantity suits core labs and research groups handling large numbers of samples. These conical screw cap tubes slot into everyday workflows for preparation, short-term holding and transfer of biological materials using conventional racks and rotors.
This article is part of Test tubes, in Tubes & vials.

Questions about Screw cap tubes, PP, brown, conical, 2.0 ml, 1000 unit(s)
What is this article?
Screw cap tubes, PP, brown, conical, 2.0 ml, 1000 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Test tubes, inside Tubes & vials, in Labware.
A test tube is the open cylindrical vessel for a small liquid, in borosilicate glass or in plastic. Rimmed and rimless mouths differ. The size is diameter by length. It is not graduated for a result, and a glass tube that will be centrifuged has a force limit.
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.
