Description
Graham condenser with cone and socket NS 19/26 is a precision laboratory glass condenser manufactured to DIN 12592 for efficient vapour cooling in distillation, reflux and extraction setups. The coiled inner tube maximises contact surface with the circulating coolant, while the outer jacket measures 250 mm in length to balance cooling capacity with compact bench or fume-hood footprint. Both ends carry standard ground joints NS 19/26 (cone and socket), ensuring direct compatibility with common round-bottom flasks, adapters and receivers. Offered as a pack of 2 pieces and weighing 0,247 kg net, the unit is produced by manufacturer Witeg and is well suited to organic synthesis, solvent recovery and analytical workflows that demand reliable heat exchange. The Graham geometry promotes turbulent flow of condensate and coolant, supporting consistent performance across a wide range of boiling points and solvent polarities. This condenser integrates readily into existing glassware trains without additional adapters, making it a practical choice for teaching laboratories, research groups and quality-control environments that rely on standardised joint sizes and proven cooling efficiency.

Questions about Graham-condensers, acc. to DIN 12592, co
What is this article?
Graham-condensers, acc. to DIN 12592, co is the article on this page. Luminix Health distributes Witeg 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.
