Description
Vertical condenser with integrated intermediate piece, socket NS 29/32 and spherical joint ball KS 35/20 is an uncoated laboratory cooler designed for Büchi rotary evaporators. Constructed from borosilicate glass 3.3, the unit combines a vertical condenser body with an integrated intermediate section for compact installation. It features a socket NS 29/32, stopcock socket NS 19/38 and KS 35/20 spherical joint ball, ensuring standardised connections within Büchi evaporator setups. The single-piece assembly has a net weight of 1,056 kg and supports efficient vapour condensation during solvent recovery, concentration and distillation procedures. This glassware component from manufacturer Rettberg belongs to the Rettberg ® range and is specified for Büchi rotary evaporator systems. The uncoated borosilicate glass 3.3 surface offers the expected chemical durability and clarity for everyday laboratory operation, while the integrated intermediate piece simplifies assembly and reduces the number of separate joints required in vertical condenser configurations.

Questions about Vertical condenser/integrated center part, socket size 29/32, spherical joint
What is this article?
Vertical condenser/integrated center part, socket size 29/32, spherical joint is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Condensers, inside Distillation & extraction glassware, in Labware.
A condenser turns vapour back to liquid. A Liebig is a straight jacket. A coil packs more surface into a short height. A cold finger cools from the inside. The water connections and the joint size are the practical specification, together with the cooled length.
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.
