Description
Graham condenser DIN 12592 with lateral glass olives is a laboratory cooling apparatus made from borosilicate glass 3.3 and marked with a blue inscription for clear bench identification. Built to DIN 12592, this Graham-type coil condenser supports efficient vapour condensation via an internal spiral path and is equipped with side glass olives for coolant tubing. The unit is 25 cm long and features matching ground joints with sleeve NS 14/23 and core NS 14/23, allowing secure connection into standard distillation and reflux assemblies. Offered as a single piece from manufacturer Hecht, it suits organic synthesis, solvent recovery and teaching laboratories that need reliable heat exchange together with the chemical and thermal durability of boro 3.3 glass. Lateral olives simplify attachment of circulating coolant lines, while the blue marking helps rapid recognition among mixed glassware. The NS 14/23 joint pair keeps the footprint compact for small- to medium-scale setups. This condenser is intended for routine analytical and preparative workflows where controlled condensation and repeatable assembly are essential.
This article is part of Condensers, in Distillation & extraction glassware.

Questions about Condensers, Graham, interchangeable inner and outer joint, with glass connector,
What is this article?
Condensers, Graham, interchangeable inner and outer joint, with glass connector, is the article on this page. Luminix Health distributes Hecht 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.
