Description
Cold finger type KF 29 - OK - A is a laboratory cold finger designed for efficient cooling and condensate collection in vacuum and distillation setups. With a coolant capacity of approximately 1000 ml and a condensate volume of around 150 ml, it supports reliable trapping of vapours and solvents. The cold-trap connection features a spherical ground joint with O-ring seal S29 for a secure interface, while the condensate drain is finished with a GL 32 thread for convenient emptying. Intended for use with Dewar type 12C, this cold finger from manufacturer KGW Isotherm offers sturdy glass construction with a net weight of 2,1 kg and a gross weight of 2,4 kg. Suitable for cold-trap applications in analytical and preparative chemistry, it enables controlled condensation of volatile compounds under reduced pressure. The capacious yet compact layout integrates readily into standard laboratory apparatus, supporting reproducible vapour management in research, quality-control and process-development environments where dependable cooling performance is required.

Questions about Cold trap Typ KF 29 - OK - A
What is this article?
Cold trap Typ KF 29 - OK - 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.
