This system is designed to rapidly evaporate/concentrate solvents by both heating the sample bottom and the incoming nitrogen. The pulsing feature allows a film of solvent to be thrown onto the sidewall, then the vortex collapses. The next pulse again creates the vortex and the process continues until the concentration level is achieved. System flexibility is greatly increased with the availability of manifolds and blocks to fit your application.
