Description
Test tubes borosilicate 3.3 with round bottom measure 18 × 180 mm and feature a wall thickness of 1,0/1,1 mm. These laboratory glass tubes are manufactured on automated machines to ensure uniform length and consistent wall dimensions, delivering dependable consumables for routine analytical and preparative work. Produced from borosilicate glass 3.3, they are especially appropriate for applications involving heating. The larger round-bottom design promotes even heat distribution and fits standard test-tube racks and heating systems. Available in packs of 100 pieces from manufacturer ISOLAB Laborgeräte, the tubes offer a practical supply format for laboratories requiring reliable glassware volumes. Chemical resistance combined with thermal stability makes them suitable for wet-chemistry workflows, sample preparation and qualitative testing. Clear glass construction permits easy visual monitoring of contents and reaction progress, supporting efficient use in research, teaching and quality-control settings that rely on consistent borosilicate laboratory tubes.
This article is part of Test tubes, in Tubes & vials.

Questions about test tube - borosilicate glass - 18x180 mm
What is this article?
test tube - borosilicate glass - 18x180 mm is the article on this page. Luminix Health distributes ISOLAB 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.
