Description
Tube assortment from 5–32 mm made of DURAN tubing is a laboratory glassware stock set produced from DURAN® borosilicate glass 3.3. The assortment comprises 32 dimensions spanning 5 mm to 32 mm and is supplied as a combined package with a total weight of 15 kg. This breadth of sizes supports glass workshops, research laboratories, and teaching facilities that need ready access to multiple tubing diameters for apparatus construction, repairs, and experimental setups. Manufactured from DURAN tubing, every size in the set shares the same stated material base, simplifying inventory when several outer diameters are required side by side. The selection is offered by manufacturer Witeg for users who prefer one consolidated assortment rather than ordering each dimension separately. Typical use includes cutting and forming stock for custom glass apparatus, educational glasswork, and general laboratory fabrication where a structured range from 5 mm through 32 mm is practical. With 15 kg of tubing across thirty-two dimensions, the assortment provides a convenient multi-size resource for routine technical glass handling and workshop stocking.

Questions about Tubes, made from DURAN tubing, assortm
What is this article?
Tubes, made from DURAN tubing, assortm is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in PVC, PTFE & other tubing, inside Tubing, hoses & fittings, in Labware.
PVC is the flexible everyday tube for water and mild aqueous liquids. PTFE is the stiff, almost inert tube for solvents. Other polymers sit between them. The bore, the wall and the chemical resistance are the specification, and the tube is cut to length.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
