Description
Test tubes 100 x 12 mm are round-bottom laboratory tubes with a beaded rim manufactured from soda-lime glass. Each tube measures 100 mm in length and 12 mm in diameter, has a wall thickness of 0,6 mm and provides a nominal volume of 9 ml. The soda-lime glass construction delivers good optical clarity and chemical resistance appropriate for general laboratory work including sample handling, reactions, heating and temporary storage. Tubes are packed in cartons of 100 pieces with a minimum order quantity of 1000 pieces, enabling economical replenishment for high-volume users. From manufacturer Marienfeld, the uniform geometry guarantees reliable fit in standard test-tube racks, heating blocks and other laboratory equipment. The round bottom and beaded rim support safe manipulation, pouring and identification while protecting the open end from chipping. These tubes serve chemistry, biology, clinical and teaching laboratories that need consistent, cost-effective glassware for daily procedures. The 0,6 mm wall thickness offers a practical balance of durability and thermal behaviour for routine bench applications.

Questions about Test tubes 100x12 mm,
What is this article?
Test tubes 100x12 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.
