Large dewar style vacuum trap. Simply insert dry ice into the middle section. Condensed vapors are dropped into separate flask for collecting large amounts of solvent or volatile compounds. A vacuum trap or "cold trap" is used to prevent vapors from entering your vacuum pump and contaminating your vacuum pump oil. If your vacuum pump ingests vapor it can be detrimental to performance and longevity of the pump. It is crucial to protect your vacuum pump in order to reach and maintain the required vacuum level, and prevent costly and unnecessary oil changes. Use a refrigerated immersion cooler for use without dry ice.


Unique features:

  • Intake is on the top left and output is on the right near the top. Both in/out ports inline and allows multiple traps to be connected inline.
  • Ground joints provide excellent sealing and a wide vapor path.
  • Dividing barrier increases efficiency by forcing vapor to travel the full vertical length of the trap before it can reach the other side creating a longer vapor path. The manufacturing process remains relatively simplistic which keeps the price down while improving overall performance. 
  • Ring baffles are added to the inner section to create additional surface area and residence time by forcing the vapor to the opposite side before escaping to the next level.
