Description
Cold finger type KF 29 - K - A is a laboratory cold trap engineered for effective condensation of vapours in vacuum and inert-atmosphere systems. It provides a coolant capacity of approximately 1000 ml together with a condensate volume of about 150 ml, offering a balanced reservoir size for routine synthetic and analytical work. The cold-trap connection uses a spherical ground joint S29, while condensate drainage is handled via a GL 32 outlet for convenient emptying. The unit is designed for use with Dewar type 12C and is supplied as a single piece weighing 2,1 kg net (2,4 kg gross) from manufacturer KGW Isotherm. Typical applications include protection of vacuum pumps from condensable solvents, collection of reaction by-products, and temporary storage of low-boiling fractions during distillation or sublimation. The spherical joint ensures a reliable vacuum-tight seal, and the GL 32 drain simplifies recovery of trapped material without dismantling the entire assembly. This cold finger is well suited to research laboratories, process-development groups and teaching environments that require dependable vapour trapping with straightforward maintenance and standardised glassware interfaces.

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