Description
Cold finger type KF 29 - GL-A is a laboratory cold finger engineered for efficient cooling and condensate collection within vacuum lines and distillation systems. It provides a coolant capacity of approximately 1000 ml together with a condensate volume of around 150 ml, enabling effective trapping of vapours. The cold-trap connection uses a GL 18 fitting with PTFE olive for a reliable seal, while the condensate drain is equipped with a GL 32 thread. Designed for pairing with Dewar type 12C vessels, this cold finger from manufacturer KGW Isotherm features robust glass construction with a net weight of 2,1 kg and a gross weight of 2,4 kg. Ideal for cold-trap duties in research and industrial laboratories, it supports controlled condensation of volatile substances under reduced pressure. The practical layout integrates smoothly into existing apparatus, delivering consistent performance for analytical workflows, solvent recovery and process development where dependable vapour management is essential.

Questions about Cold trap Typ KF 29 - GL -A
What is this article?
Cold trap Typ KF 29 - GL -A is the article on this page. Luminix Health distributes KGW Isotherm for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
