Cold Trap

Freeze Trap VA-800R

Code No.： 0057755-000

This device efficiently collects water sublimated by centrifugal concentration, assists the displacement volume of the pump, and directly contributes to the concentration speed. It reduces cross-contamination by agglomerating the vapor phase of the concentrated and sublimating sample.

Applications

●As a Cold Trap for the Centrifugal Concentrator
●As a preliminary freezing tank for Lyophilization
●As a freezing tank during freeze-fracturing

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)

Digital Temperature Monitor

The temp. inside the Cooling chamber can be checked in the VA-800R (Slight deviations may occur in the displayed temp. depending on the usage conditions.).
