Description
Immersion cooler NS 19/26 is a laboratory dephlegmator of the PERCISO series featuring ground joint NS 19/26, an effective length of 100 mm and an overall length of 185 mm. Designed as a glass immersion cooler for condensation and reflux duties, it fits apparatus that use the NS 19/26 standard joint. The effective cooling length of 100 mm within a total length of 185 mm gives a practical immersion profile for flasks and reactors of corresponding size. Net weight and gross weight are each 0,034 kg; the item is supplied as 1 pc. From manufacturer Witeg (Germany, Baden-Württemberg), this cooler is classified among coil coolers and supports distillation, solvent handling and general laboratory condensation tasks that require a reliable NS 19/26 connection. The PERCISO specification documents joint size and lengths clearly for method transfer and glassware inventories. Compatibility with matching ground-joint components allows direct integration into existing assemblies without adapters, while the stated mass of 0,034 kg aids balance calculations for portable or suspended setups. All dimensional and weight data follow the manufacturer description exactly.

Questions about Immersion coolers (dephlegmators) PERCI
What is this article?
Immersion coolers (dephlegmators) PERCI is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labware.
A still head, an adapter or a column is the glass between the boiling flask and the condenser. A Vigreux or packed column gives the vapour a surface so a closer-boiling mixture can separate. The joint sizes at both ends have to match the flask and the condenser.
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.
