Description
Calcium chloride tubes U-shaped 125 mm are laboratory drying tubes intended for solid desiccants in gas-drying and purification setups. The U-form construction with side tubes offers a convenient geometry for packing calcium chloride and for linking into apparatus lines. With a length of 125 mm and an inner diameter of 16 mm, the tube provides a mid-size format suited to bench-scale drying trains and general gas-conditioning work. Each unit is supplied as 1 pc and has a net weight of 0,038 kg together with a gross weight of 0,038 kg. These calcium chloride tubes from manufacturer Witeg serve routine moisture-removal duties in analytical chemistry, preparative support and everyday laboratory gas handling. The U-shaped profile supports stable positioning and effective contact between the flowing gas and the desiccant bed. Side tubes allow straightforward integration into simple drying arrangements where a 125 mm U-tube with 16 mm inner diameter is specified. Laboratories seeking this intermediate length for standard desiccant packing will find the tube a practical option for regular drying applications.
This article is part of Test tubes, in Tubes & vials.

Questions about Drying tubes, U-shaped, with side conn
What is this article?
Drying tubes, U-shaped, with side conn 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.
