Cold Traps

Cold traps support New Zealand laboratory vacuum, distillation, solvent recovery and vapour condensation workflows by capturing condensable vapours before they reach vacuum pumps or downstream equipment.

John Morris Group supplies cold traps, Dewar flask cold traps, condensate drain models and hose connection accessories through page-supported supply channels including Labfriend, helping NZ teams source vapour trapping equipment for Laboratory, Industrial and sample preparation workflows.

Cold Traps for New Zealand Vacuum and Solvent Workflows

Cold traps are used where laboratories need to condense vapours, moisture or solvents before they enter a vacuum pump or connected system. The visible range includes Lenz-Laborglas cold traps with condensate drain and coolant capacities of 200 ml and 500 ml, cold traps with cone and bush NS 29/32 connections, Boro 3.3 glass formats, KGW Schieder cold traps supplied with Dewar flasks, plastic support rings and drain openings, plus straight and bent PP hose connections for screw caps.

  • Vacuum pump protection: Use cold traps to help reduce vapour, solvent or moisture carryover into vacuum pumps.
  • Condensate handling: Choose condensate drain models where collected liquid needs to be removed more easily after use.
  • Dewar flask cold traps: Select KGW Schieder assemblies where Dewar flask cooling and stable cold trap support are required.
  • Connection compatibility: Match NS 29/32 joints, hose connections, coolant capacity and trap geometry to the existing vacuum setup.

How to Choose Cold Traps for NZ Laboratories

Before ordering, technical buyers should confirm solvent type, coolant type, vacuum pump compatibility, trap capacity, condensate volume, joint size, hose connection style, glass material and whether a condensate drain is required. Related procurement may include Vacuum Pumps, Laboratory Evaporators and Laboratory Glassware.

Applications Across NZ Laboratory Vacuum Systems

  • Vacuum workflows: Capture condensable vapours before they reach pumps, manifolds or downstream vacuum equipment.
  • Solvent trapping: Condense compatible solvent vapours during evaporation, distillation or sample preparation workflows.
  • Moisture protection: Reduce moisture load in connected systems where vapour capture supports cleaner vacuum operation.
  • Research and analytical preparation: Support distillation, vacuum drying, rotary evaporation and concentration workflows in technical laboratories.

Supported Supply Channel and Related Categories

The visible category range is supplied through Labfriend, covering Lenz-Laborglas cold traps, KGW Schieder Dewar flask cold traps and plastic hose connection accessories. NZ procurement teams building a wider vacuum setup may also review Rotary Evaporators, Laboratory Concentrators and wider Laboratory and Scientific Equipment.
