Cold Trap



Efficiently traps water vapor and toxic substances discharged from vacuum oven and rotary evaporator to protect the vacuum pump


  • Excellent choice to extract acid and organic solvents with the optional glass condenser
  • Efficiently reduces vapor inhalation amount to the vacuum pump
  • Can be used as a low temperature tank as well as pre-cooling tank
  • Utilizes R404A (CA301) and R600a and mixed coolants (CA801)
  • Space saving and highly mobile on wheels
