These tubes measure approximately 180 mm in length with a diameter of 20 mm and are manufactured from borosilicate glass 3.3. The heavy-wall construction combined with a beaded rim defines their design for routine laboratory use as reagenzgläser, reagenzröhrchen or probenröhrchen. Pack size is 100 pc(s), providing a practical quantity for laboratory stocking and daily operations. Dimensions according to specifications are length 180 mm and diameter 20 mm. Available from manufacturer Hecht, the tubes suit general sample containment, mixing and preparative procedures where borosilicate glass 3.3 vessels of these approximate outer dimensions are required. The combination of heavy-wall form and beaded rim supports standard handling in chemical and analytical workflows. Material, length and diameter data match the stated scientific specifications exactly, ensuring clear identification for laboratory procurement and inventory purposes across typical test-tube applications.

Questions about Test tubes, borosilicate glass 3.3, heavy wall with rim mm Ø ca. 180 x20
What is this article?
Test tubes, borosilicate glass 3.3, heavy wall with rim mm Ø ca. 180 x20 is the article on this page. Luminix Health distributes Hecht 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.
