Features

Direct collecting into a Cooling chamber or trapping into a Glass condenser

Use the Lid with nozzle (sold separately) when trapping vapors directly to the Cooling chamber (See left figure below). The advantage of directly trapping is that the collection efficiency is very high. This is because it is directly cooled by a cooling pipe while maintaining capacity. The solvents are limited to water and non-corrosive alcohol as the solvent is directly in contact with the unit. For other solvents, trap by using the Glass condenser (sold separately) (See right figure).

Cooling chamber inside (VA-800R)

For simple Lyophilization

Simple Lyophilization can be performed in a cold trap by combining the VD series Multiple tubes and the FK-2100 freezing option. Ask us for details.
