MAXTRAP Vacuum Cold Trap



Cascade’s MAXTRAP Vacuum Cold Traps are a revolutionary lab-grade cold trap that goes beyond the ordinary.

Built upon our extensive expertise in vacuum best practices, this exceptional tool is specifically designed for customers seeking efficient solutions for time-sensitive, high-throughput, production-focused vacuum purging or drying applications.

With MAXTRAP, you can preserve and extend the life of your vacuum pump, ensuring minimal maintenance intervals. Experience the next level of cold trapping technology with Cascade’s MAXTRAP Vacuum Cold Traps!


The MAXTRAP Difference.

The key to quality cold trap performance is time, surface area, and temperature.

Time:  Most cold traps have very narrow inlets and outlets, slowing down your process. Not Cascade’s MAXTRAP! Full KF25 inlet and outlet connections never reduce flow.

Surface Area:  Most cold traps have glass or a smaller surface area to collect the matter your vacuum pump would otherwise ingest. Cascade’s MAXTRAP surface area is a patent pending series of filter baffles inside the COLDWELL stainless trap.

Temperature:  Cascade’s MAXTRAP features the mechanically refrigerated system built in the USA by Labconco – a leader in laboratory equipment.

More information


At very cold temperatures, solvents and even oxygen can re-condense back into liquid. This is potentially explosive. Liquid oxygen is a light blue color and can condense into a cold trap if a pump has sucked air through the trap when the trap is very cold. Always follow your standard operating procedures and safety guidelines.

Don’t Stop: Keep Processing while trap is being reclaimed, cleaned, refreshed
Cold traps can become full or the captured material freezes and blocks flow. For high moisture, outgassing, 24 hour processing/vacuum purging consider adding a second, spare COLDWELL trap.

The secondary COLDWELL can be dropped into place so processing continues while the full trap is cleaned, defrosted.


Quick Start Up Tips:

  • Remove shipping foam from reservoir bottom prior to use
  • Fill reservoir with 800ml (+/-3.5 cups) ethanol to marked line
  • Monitor ethanol levels inside reservoir
  • Allow at least 30 mins for trap to cool
  • Keep side vents clear. Allow at least 4″ for airflow
  • Monitor interior of stainless trap for clogging
  • Short tube – attach to vacuum pump
  • Tall tube – attach to vacuum oven
