Description
Glass inlet tubes NS 29/32 are precision laboratory glassware components intended for controlled introduction of gases into reaction vessels and flasks. They feature a standard NS 29/32 ground joint, a right-angled bent olive for secure flexible-tubing connection, and an installation length of 250 mm. A integrated valve stopcock permits accurate regulation and shut-off of the gas stream during experimental work. Produced in the PRECISO quality line from manufacturer Witeg, these inlet tubes deliver consistent dimensional accuracy and chemical resistance suited to organic synthesis, inert-atmosphere techniques, gas sparging and analytical procedures. The compact design integrates readily with complementary NS 29/32 jointed apparatus while the net weight of only 0,05 kg ensures convenient handling and storage. Laboratories value the robust construction that withstands repeated use under standard conditions and supports reliable gas-delivery workflows in both research and routine analytical settings.

Questions about Inlet tubes ST 29/32
What is this article?
Inlet tubes ST 29/32 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.
