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
