Description
Bend with 90° angle and two cone joints NS 29/32 is a laboratory glass adapter intended for directional changes in ground-joint apparatus. Made from borosilicate glass 3.3, it offers a standardised NS interface for connecting flasks, condensers, receivers and related components in distillation, reflux and general synthesis setups. Both ends are cone (male) joints of size NS 29/32, allowing direct insertion into matching sockets and a compact right-angle path for vapours or liquids. The net weight is 0,050 kg, keeping the piece light for bench and fume-hood assemblies while remaining suitable for routine laboratory handling. Supplied as one piece, this adapter falls within the transition-piece and ground-joint accessory range used wherever modular glass trains must be redirected without extra fittings. The item is produced by manufacturer Rettberg and carries the Rettberg® mark; origin is Germany. Typical applications include organic preparation lines, solvent recovery glassware and analytical apparatus built on the NS 29/32 standard. As a dedicated adapter it supports flexible reconfiguration of existing setups while preserving joint alignment and interchangeability across common laboratory glass systems.

Questions about Bend, angle 90°, 2x cone size 29/32
What is this article?
Bend, angle 90°, 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.
