Straight vacuum adapter with suction tube and drip tip, NS 19/26 is a laboratory glassware fitting intended for distillation and vacuum work. It comprises a straight body fitted with an integrated suction tube for vacuum connection together with a drip tip that directs condensate flow. Both the socket and the cone are ground to NS 19/26, allowing direct mating with matching flasks, condensers or receivers. The unit has a net weight of 0,036 kg and a gross weight of 0,036 kg, making it a compact addition to standard glassware assemblies. This vacuum adapter from manufacturer Witeg belongs to the family of distillation adapters used for reduced-pressure distillations, solvent recovery and fraction collection. The straight geometry keeps the vapour path short while the drip tip helps control liquid transfer into the receiving vessel. Compatible with common European ground-joint systems, the adapter can be inserted into multi-piece distillation trains or rotary-evaporator setups. Supplied as a single piece, it supports flexible configuration of laboratory vacuum lines for organic synthesis, purification and analytical sample preparation.
This article is part of Trays, bowls & tubs, in Dishes, crucibles & porcelain.

Questions about Receiver adapters, straight, w. vacuum
What is this article?
Receiver adapters, straight, w. vacuum is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Trays, bowls & tubs, inside Dishes, crucibles & porcelain, in Labmateriaal.
A laboratory tray, bowl or tub is an open vessel for holding, staining, drying or carrying many small items at once. Polypropylene trays resist a knock and many aqueous liquids. Porcelain takes heat. The useful numbers are the bottom size and the depth, because that is the working area.
A dish is an open vessel for drying, evaporating or holding a solid. Porcelain and glazed ceramic take a higher temperature than borosilicate glass, which is why a crucible, not a beaker, goes into a furnace. A watch glass covers, or holds a small amount for drying. A mortar is for grinding. The temperature and the chemical, not the shape alone, choose the material. Laboratory ware of this family is listed under ISO laboratory ware.
