Description
Sample tubes 12,0 ml measuring 16 x 100 mm are round-bottom polypropylene vessels intended for laboratory sample collection and handling. Fabricated from PP, they offer a robust, lightweight format for liquid samples in analytical, preparative and general laboratory settings. The round bottom supports effective mixing and sample recovery, while the 16 x 100 mm dimensions fit typical racks and workflows associated with sample tubes and sample vials. A nominal volume of 12 ml provides additional capacity for larger aliquots compared with smaller tube formats, which is useful when intermediate storage or multi-step sample preparation is required. Packs contain 1000 pieces, giving laboratories a convenient bulk quantity for continuous bench use and high-throughput sample processing. These tubes from manufacturer Witeg are positioned for everyday sample-tube applications where polypropylene durability and a simple round-bottom geometry are sufficient. The supply unit is specified with a net weight of 4 kg and a gross weight of 4 kg, helping purchasing and logistics teams plan stock levels for routine laboratory operations.

Questions about Test tube 12,0 ml 16 x 100 mm PP round
What is this article?
Test tube 12,0 ml 16 x 100 mm PP round is the article on this page. Luminix Health distributes Witeg 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.
