Description
Bend with 75° angle and two cone joints NS 29/32 is a laboratory glass adapter designed for angled routing within standard ground-joint apparatus. Fabricated from borosilicate glass 3.3, it delivers a reliable NS interface for linking flasks, condensers, receivers and related components in distillation, reflux and general laboratory workflows. Both ends are cone (male) joints of size NS 29/32, permitting direct insertion into matching sockets and a defined 75° directional change for vapours or liquids. The net weight is 0,064 kg, offering a practical balance of robustness and manageable mass for bench-top and fume-hood assemblies. Supplied as one piece, the item sits in the transition-piece and ground-joint accessory group used wherever modular glass trains need redirection without additional couplings. It is made by manufacturer Rettberg and carries the Rettberg® mark; origin is Germany. Common applications include organic preparation lines, solvent recovery glassware and analytical apparatus based on the NS 29/32 joint standard. As a dedicated adapter it enables flexible reconfiguration of existing setups while preserving joint alignment and interchangeability across routine laboratory glass systems.

Questions about Bend, angle 75°, 2x cone size 29/32
What is this article?
Bend, angle 75°, 2x cone size 29/32 is the article on this page. Luminix Health distributes Rettberg 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.
