Direct concentration

We recommend direct concentration of reaction mixtures

for sensitive reaction products, which are further processed

directly in the same size (without transfer into another

vessel).

If you directly evaporate after a parallel reaction, the follo-

wing procedure is used after the reaction:

•Inertgassupplyanddischargeisinterrupted(for ex-

ample via hose clamps or by using a three-way cock).

• Thesuitablevacuumisapplied,vibratingmotion and

heating of rack are started according to the Operating

Instructions of the Syncore Apparatus Line.

If the shaking movement is concluded before the sample

temperature is below the lowest boiling point, the mixture

can start to intensely boil in a boiling delay, which can lead

to a loss of the reaction mixture.

The vacuum conditions are to be adapted to the sample

temperature. Make sure that the samples in the rack cool

slowly after the reaction and that too low vacuum can lead

to boiling delay.
