Description
Test tubes with conical base are polystyrene (PS) sample vessels offering a 12 ml working volume and dimensions of 18 x 105 mm. The conical geometry concentrates small residual volumes at the tip, which is useful for sedimentation steps, careful aspiration and protocols where complete recovery of the lower phase matters. Supplied as 1500 pc(s) per pack with a total weight of 8,650 kg, they support continuous laboratory consumption without frequent reordering. These tubes from manufacturer Ratiolab are intended for general laboratory use as disposable plasticware for sample collection, intermediate storage and routine processing. Clear PS walls allow easy observation of fill level and sample appearance during handling. Attention: the article will be without CE/IVD marking in future; suitability for diagnostic or other regulated applications must be assessed from the actual labelling and applicable regulations. Choose this conical 12 ml format when a taller, wider tube with a pointed base is preferred over a simple round bottom for bench and instrument workflows compatible with polystyrene.
This article is part of Test tubes, in Tubes & vials.

Questions about Test tubes, conical base, 12 ml, PS, 18 x 105 mm, conical, 1500 unit(s)
What is this article?
Test tubes, conical base, 12 ml, PS, 18 x 105 mm, conical, 1500 unit(s) is the article on this page. Luminix Health distributes Ratiolab 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.
