Temperature of the cooling medium

The temperature of the cooling medium signiﬁcantly affects

the condensation of the solvent vapors. Select a cooling

medium temperature that lies at least 15 to 20 °C below

the vapor pressure of the sample. Efﬁcient cooling in con-

densation is ensured whenever the solvent condenses out

completely in the ﬁrst third of the cooling coil.

In addition to the condensation done under a vacuum,

we recommend also carrying out a second condensation

downstream from the vacuum pump. Re-condensation

under atmospheric pressure downstream from the vacuum

pump (e.g., using the BUCHI VAC V-503 diaphragm pump)

makes it possible to condense any fumes of solvents and

chemicals that may still be present efﬁciently and safely.
