Description
Graham condenser, DIN 12592, with lateral threaded connection and plastic screw fitting is a laboratory condenser fabricated from borosilicate glass 3.3 for condensation duties in distillation and reflux assemblies. Blue inscription on the body supports quick visual identification among other glassware. With a length of 25 cm, the unit is fitted with a socket joint NS 29/32 and a cone joint NS 29/32 so that it couples directly to standardised ground-glass apparatus. Cooling water is connected through the lateral threaded ports and secured by the plastic screw fitting, offering a practical alternative to glass olives for flexible tubing. The Graham design places a coiled cooling path inside a compact jacket, which is useful when bench space is limited yet effective vapour condensation is still required. This condenser from manufacturer Hecht follows DIN 12592 conventions and is supplied as one piece for laboratories that rely on borosilicate 3.3 components. Matching NS 29/32 joints, defined length and threaded coolant connections make it a practical choice for preparative chemistry, solvent recovery and routine teaching or research setups that demand reliable glass interfaces.
This article is part of Condensers, in Distillation & extraction glassware.

Questions about Condensers, Graham, interchangeable inner and outer joint, with PP screw
What is this article?
Condensers, Graham, interchangeable inner and outer joint, with PP screw 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.
