Description
Cold trap 500 ml is a one-piece laboratory glassware item equipped with lateral connections terminating in glass flanges DN 25. Manufactured from borosilicate glass 3.3, the trap offers the thermal-shock resistance and chemical durability needed for vacuum condensation and vapour-trapping duties. The single-piece construction reduces joint-related leakage risks and simplifies cleaning and assembly within vacuum lines or rotary-evaporator systems. Lateral glass flanges DN 25 provide standardised, robust interfaces for connection to complementary glassware or vacuum components. With a working volume of 500 ml this cold trap accommodates larger condensate loads than smaller variants while remaining compact enough for typical laboratory benches. The cold trap from manufacturer Rettberg is supplied as one piece and has a net weight of 0,625 kg. It is suited to research, analytical and process laboratories that require reliable capture of condensable vapours under reduced pressure. The combination of borosilicate glass 3.3 and DN 25 flanged side arms ensures compatibility with common glass vacuum apparatus and supports consistent performance in everyday trapping applications.

Questions about Cooling trap, 500 ml, one-piece, with side connections DN 25
What is this article?
Cooling trap, 500 ml, one-piece, with side connections DN 25 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.
