Description
Test tubes 26 x 150 mm NS 24/29 are robust laboratory vessels designed for sample processing, moderate-volume reactions and secure temporary storage. Fabricated from DURAN tubing, they offer the chemical inertness and thermal endurance expected from high-quality borosilicate glass. Each tube is equipped with a round bottom for efficient heating, an ungraduated wall that keeps the interior fully visible, and an NS-PE stopper matched to the NS 24/29 ground joint for tight closure. Available in packs of 10 pieces from manufacturer Witeg, the tubes measure 26 mm in diameter by 150 mm in length and weigh 0,044 kg net per piece. The larger joint size facilitates connection to a broad range of standard NS glassware, enabling use in distillation, reflux or multi-component assemblies. Their solid construction withstands repeated thermal cycling and cleaning cycles, making them well suited to teaching laboratories, analytical benches and industrial quality-control environments. These tubes combine practical capacity with reliable sealing and dimensional consistency for everyday scientific work.

Questions about Test tubes 26 x 150mm ST 24/29
What is this article?
Test tubes 26 x 150mm ST 24/29 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.
