Cold Trap

Freeze Trap VA-250F

Code No.: 0029108-000

Retrieves solvent evaporated by a centrifugal concentrator. Other than Concentrating promotion it enables to prevent release into the atmosphere and inflow to the vacuum pump.


Applications

As a Cold Trap for Centrifugal Concentrator

Features

Traps vapor into Cooling chamber directly or Glass condenser by solvents
Attach Lid with nozzle (sold separately) to Cooling chamber when trapping vapor directly (See left figure below). The advantage of directly trapping is the capacity gets more and the cooling temp almost the same as the trap temp. However, the solvents are limited to water and alcohol as the solvent directly contact the unit. In other solvents, trap by placing it into Glass condenser (sold separately) in the chamber (See below).
