Description
Cold finger, two-part, type KFL 29-OK-Z is a laboratory cold-trap insert developed for efficient condensation of vapours under vacuum in distillation, synthesis and sample-preparation systems. It combines a coolant capacity of approximately 2000 ml with a condensate volume of around 250 ml, enabling stable performance during extended cooling periods and higher vapour throughputs. The two-part cold-trap construction incorporates a spherical ground-joint connection S29 equipped with an O-ring seal, delivering enhanced leak tightness and simplified assembly compared with plain ground joints. The unit is matched to Dewar type 18C vessels. Manufactured by KGW Isotherm, this cold finger serves organic chemistry, solvent recovery, freeze-drying support and analytical laboratories that demand reliable vapour trapping. The O-ring-sealed spherical joint improves vacuum integrity while the two-part layout facilitates thorough cleaning of internal surfaces. Net weight is 2,8 kg and gross weight 3,1 kg. Supplied as one piece, the KFL 29-OK-Z model provides a practical, service-friendly cold-trap solution for modern laboratory vacuum installations.

Questions about Cold trap, two sections, Typ KFL 29-OK-Z
What is this article?
Cold trap, two sections, Typ KFL 29-OK-Z 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.
