Beschreibung
Cold trap 250 ml is a one-piece laboratory glassware component featuring a top GL 45 thread with closure cap and lateral GL 14 threaded connections supplied with screw connection caps and straight plastic olives of 8,6 mm. Fabricated from borosilicate glass 3.3, the trap provides the chemical resistance and thermal stability required for vacuum and condensation work in research and process laboratories. The integrated one-piece design minimises potential leak points while the GL 45 top opening facilitates convenient filling, emptying or attachment of additional fittings. Lateral GL 14 ports equipped with polypropylene olives enable straightforward tubing connections for coolant or vapour lines. This cold trap from manufacturer Rettberg is delivered as a single unit with a net weight of 0,451 kg and is intended for use in vacuum lines, rotary-evaporator setups and other systems where condensable vapours must be captured. The combination of borosilicate glass 3.3, GL threaded ports and ready-to-use plastic olives makes the 250 ml cold trap a practical choice for routine laboratory condensation and trapping applications.

Questions about Cooling trap, 250 ml, one-piece, GL 45, side connections thread GL 14
What is this article?
Cooling trap, 250 ml, one-piece, GL 45, side connections thread GL 14 is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Laborbedarf.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
