Description
Gas collection tube "Safety" 500 ml is a specialised laboratory vessel for safe collection and temporary storage of gas samples. Manufactured from DURAN tubing, the 500 ml tube is fitted with two valve stopcocks that incorporate PTFE spindles together with adjustable sealing rings and over-rotation protection, reducing the risk of seal damage during repeated opening and closing. The Safety configuration supports controlled fill, isolation and release sequences in analytical chemistry, environmental monitoring and process-gas handling. The PTFE spindle and adjustable sealing arrangement help maintain a reliable gas-tight closure under routine laboratory conditions. Offered by Witeg, this collection tube is intended for users who require durable borosilicate construction combined with protected stopcock hardware. Net weight is 0,264 kg. Supplied as one piece, it fits standard laboratory gas-handling setups where secure shut-off and chemical resistance of the wetted parts are essential for reproducible sampling work.

Questions about Gas sampling tubes ''''safety'''', 500 ml m
What is this article?
Gas sampling tubes ''''safety'''', 500 ml m 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.
