MAXTRAP105 -105°C Vacuum Cold Trap, 120V


MAXTRAP105 -105°C Vacuum Cold Trap, 120V




Cascade’s MAXTRAP105 is not an ordinary lab-grade cold trap. Cascade has integrated  features necessary for time-sensitive, high-throughput, production-focused vacuum purging or drying applications.


MAXTRAP105 Cold Trap Includes:


  • Cascade’s COLDWELL 304 Stainless Steel Trap Insert (Patent pending baffle system)


  • 3 Quart Capacity (2839 ml)


  • Viton Gasket for Vacuum Integrity


  • Labconco -105°C Refrigerated Base


  • Green CFC / HFC Free Refrigerants


  • Power Cord


  • 3mm Neoprene Insulator Cap


  • Requires 800ml (~ 3.5 cups) of a transfer fluid such as ethanol. Not Included. Cascade recommends: ethanol, glycol, cryo-cool fluids


  • Quality Made in USA


  • 1 Year Warranty


  • Connection Lines and hardware: 4′ of 1″ Diameter Vacuum Tubing with KF-25 Flanges on each side. KF-25 clamps, centering rings for the connection tube






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


MAXTRAP105 Differences:


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 MAXTRAP105! 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 MAXTRAP105 surface area is a patent pending series of filter baffles inside the COLDWELL stainless trap.
