Description
Reflux condenser with height 320 mm and cooling surface 2000 cm² is a short-design laboratory cooler equipped with Rotulex ball joint S 41/25 and GL 18 cooling connections. Fabricated from borosilicate glass 3.3, it is intended for use with reaction vessels in chemical and preparative work. The compact construction delivers a generous cooling area within a limited footprint, making it suitable for reflux operations where bench space is constrained. Jacket length measures 320 mm and net weight is 1,200 kg. This model from manufacturer Rettberg combines robust glass quality with practical connection geometry for reliable condensation performance. The short Bauform supports efficient vapour return while maintaining clear visibility of the process. Ideal for organic synthesis, distillation setups and general laboratory reflux applications requiring durable borosilicate glassware with standardised GL and spherical joints.
This article is part of Condensers, in Distillation & extraction glassware.

Questions about Reflux condenser (short type), height 320 mm, thread GL 18,
What is this article?
Reflux condenser (short type), height 320 mm, thread GL 18, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Condenseurs, inside Verrerie de distillation & d'extraction, in Matériel de laboratoire.
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.
