Beschrijving
Reflux condenser with height 270 mm and cooling surface 800 cm² is a short-design laboratory cooler fitted with Rotulex ball joint S 41/25 and GL 14 cooling connections. Made from borosilicate glass 3.3, the unit is designed for attachment to reaction vessels in everyday laboratory practice. Its compact form provides effective condensation capacity while occupying minimal vertical space. Jacket length is 270 mm and net weight is 0,600 kg. Supplied by manufacturer Rettberg, this cooler offers dependable performance for reflux and related thermal processes. The combination of standardised spherical joint and GL coolant ports ensures straightforward integration into existing glass assemblies. Suitable for organic reactions, solvent recovery and general preparative chemistry where a smaller cooling surface and reduced height are advantageous. Durable borosilicate construction supports repeated use under typical laboratory thermal conditions.

Questions about Reflux condenser (short type), height 270 mm, thread GL 14,
What is this article?
Reflux condenser (short type), height 270 mm, thread GL 14, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Koelers, inside Destillatie- & extractieglaswerk, in Labmateriaal.
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.
