Description
The vacuum connection for vertical condensers features a cone NS 29/32 joint together with a lateral GL 14 thread and an upper GL 18 thread. Manufactured from borosilicate glass 3.3, this adapter is designed to link a vertical condenser to the vacuum line while providing convenient screw-thread ports for tubing and closures. The lateral GL 14 outlet is supplied with a screw coupling cap and a plastic olive of 8,6 mm, and the top GL 18 thread carries a screw closure cap, enabling straightforward hose attachment and sealing. With a net weight of 0,044 kg and supplied as a single piece, the component belongs to the laboratory glassware range from manufacturer Rettberg. Borosilicate glass 3.3 ensures chemical resistance and thermal durability for routine distillation and condensation work. Laboratories employ this vacuum adapter wherever an NS 29/32 cone interface and dual GL ports are required on vertical condenser assemblies, integrating it cleanly into existing rotary-evaporator or distillation glassware. It serves as a practical interconnect within the transition-piece and screw-coupling category for vacuum-controlled condenser setups.
This article is part of Condensers, in Distillation & extraction glassware.

What is this article?
Vacuum connection f. vertical condenser, cone size 29/32, side thread GL 14 and 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.
