Product Info
Cold Trap
Freeze Trap VA-250F
Code No.： 0029108-000
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).
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.Specifications
