Description
SVS screw connection NS 24/29 is a laboratory glass adapter that links a standard ground cone joint NS 24/29 to a GL 45 screw thread. Configured as an SVS thread transition piece and supplied as glass parts only, it conforms to DIN 12257 and provides a dependable interface between conventional ground-joint glassware and threaded laboratory components. The clear glass construction allows visual inspection of the joint area and maintains chemical resistance typical of borosilicate laboratory ware. Offered by manufacturer Witeg, this adapter is suited to distillation trains, reaction vessels and vacuum lines where an NS 24/29 to GL 45 conversion is needed. Its precise cone and thread geometry support reproducible, low-leak assemblies when paired with matching seals and connectors. The compact single-unit format simplifies inventory and replacement on the bench. Researchers and technicians working with medium-scale organic or preparative setups will find the NS 24/29–GL 45 combination a practical addition to modular glass systems requiring standardised screw-thread transitions.

Questions about Screw-thread, with cone ST 24/29
What is this article?
Screw-thread, with cone ST 24/29 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labware.
A still head, an adapter or a column is the glass between the boiling flask and the condenser. A Vigreux or packed column gives the vapour a surface so a closer-boiling mixture can separate. The joint sizes at both ends have to match the flask and the condenser.
Distillation separates liquids by boiling point. A condenser turns the vapour back into liquid: Liebig, coil and cold-finger shapes differ in how much cooling surface they offer. A still head and a column sit between the flask and the condenser. A Soxhlet extractor washes a solid again and again with the same solvent. Ground joints have a standard size, and the joint, not the flask, is what has to match. The pieces are indexed under ISO laboratory glassware.
