Raising the Bar for Cold Trap Kits

This Cold Trap Kit from Lab Society features a Dewar-style cold finger condenser. It has a large opening at the top for use with dry ice, acetone, liquid nitrogen, or similar solvents with a low melting point.

The large amount of cooling surface area of this cold trap kit makes it well-suited for high-volume solvent removal, as well as for the retention of collected volatiles.

Protect your vacuum pumps.

Cold traps require a vacuum pump to function properly, and they can extend the life of your pump.

This is achieved by condensing vapors (other than permanent gases) into a liquid or solid form. By condensing them in the cold trap, you prevent those vapors from contaminating your vacuum pumps. Unwanted vapor condensation in your pump’s internal components can reduce its lifespan, costing you money.

A functional and rugged cold trap kit.

The detachable 500mL round bottom flask (RBF) utilizes a 45/50 Rodaviss anti-seizing joint for connection to the main trap body. When installed properly, the Rodaviss cap applies vertical force to separate the vessel from the body when unscrewed. Threaded hose connections are staggered for maximum vapor stream exposure (in through bottom left, out through top right) and feature GL-18 screw caps with Viton seals for 3/8 ″ ID hosing.

Note: You will need to use dry ice or an immersion chiller for the cold trap to function properly when dealing with volatiles.
