Description
Test tubes 75 x 12 mm are round-bottom laboratory tubes with a beaded rim made from soda-lime glass. Each tube measures 75 mm in length and 12 mm in diameter, features a wall thickness of 0,6 mm and offers a nominal volume of 6 ml. The soda-lime glass provides clear visibility and suitable chemical resistance for general laboratory procedures such as sample preparation, qualitative tests, heating and short-term storage. Tubes are packed in cartons of 100 pieces and supplied in units of 1000 pieces, supporting efficient stock management in busy laboratories. From manufacturer Marienfeld, the consistent dimensions ensure reliable seating in standard racks, blocks and centrifuges. The round bottom and beaded rim facilitate secure handling, pouring and labelling while reducing the chance of cracking at the open end. These tubes are well suited to chemistry, biology, clinical and educational laboratories that require economical, uniform glassware for routine workflows. The robust wall thickness of 0,6 mm balances mechanical strength with thermal performance for everyday bench applications.

Questions about Test tubes 75x12 mm,
What is this article?
Test tubes 75x12 mm, is the article on this page. Luminix Health distributes Marienfeld 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.
