Description
The U-tube with two GL 18/10 connections is a laboratory glassware item intended for drying-tube and related gas-path applications. Its U-shaped form provides a compact path that can be packed or used as a connecting element between apparatus sections requiring screw-thread GL interfaces at both ends. The dual GL 18/10 ports support secure coupling to compatible flasks, adapters or tubing systems in modular laboratory setups. Supplied as a single piece with a net weight of 0,036 kg, the tube is practical for routine handling and storage. This U-tube from manufacturer Witeg suits drying trains, gas scrubbing paths, protective inlet arrangements and general preparative workflows where a simple U-geometry is preferred. Research, teaching and analytical laboratories can integrate the component into distillation-adjacent assemblies, inert-gas lines or moisture-protection configurations. The clear two-port design keeps assembly straightforward and supports repeated connection cycles with standard GL fittings. The product addresses everyday needs for reliable glass connecting pieces in European laboratory environments focused on organic synthesis support, sample preparation and educational demonstrations.

Questions about U-tube, 2 GL 18/10
What is this article?
U-tube, 2 GL 18/10 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.
