Description
Cold finger type KF 29-K is a laboratory cooling accessory designed for condensation and cold-trap applications. It features a coolant capacity of approximately 1000 ml and a condensate volume of approximately 150 ml, making it suitable for moderate-scale vacuum or distillation set-ups. The unit connects via a ball-joint cold-trap interface S29 and is intended for use with Dewar type 12C. Manufactured by KGW Isotherm, the cold finger supports efficient cooling of vapours and collection of condensate under controlled laboratory conditions. Net weight is 2,1 kg and gross weight 2,4 kg, reflecting a solid glass construction typical of precision laboratory glassware. Supplied as a single piece, it integrates into existing cold-trap assemblies where an S29 spherical joint is specified. The design allows straightforward filling with coolant and subsequent recovery of condensed material. This cold finger is appropriate for research and analytical laboratories performing vacuum distillations, freeze-drying preparations or similar processes that require reliable intermediate cooling stages.

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