Description
Cold trap, 500 ml, 2-piece, is a borosilicate-glass vacuum accessory engineered for efficient condensate capture in high-vacuum installations. The unit offers a total capacity of 500 ml and an approximate condensate volume of 200 ml. Its lower part is equipped with a KF DN 50 flange including gasket and clamp, while the upper part features two thick-walled KF DN 16 connections plus an additional standard KF DN 16 port intended for a Pirani measuring gauge. This arrangement facilitates direct mounting on high-vacuum lines, metal flange components and comparable systems. Produced by manufacturer Rettberg from borosilicate glass 3.3, the two-piece design allows convenient separation of the condensate section for emptying and maintenance. The extra DN 16 connection expands monitoring capability without compromising the primary vacuum path. Compact yet fully functional, the cold trap is well suited to laboratory and pilot-scale vacuum manifolds requiring reliable vapour trapping and optional pressure sensing.

Questions about Cooling trap, 500 ml, 2-piece, lower part DN 50, upper part 2x DN 16
What is this article?
Cooling trap, 500 ml, 2-piece, lower part DN 50, upper part 2x DN 16 is the article on this page. Luminix Health distributes Rettberg 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.
