The optimum method for removing solvent from
large numbers of small (up to 20ml) samples at
the same time is by centrifugal evaporation.
Larger samples (e.g. synthesis products in round
bottom flasks) can be fairly rapidly processed
with a rotary evaporator, but this method
accommodates one sample at a time. In addition,
optimisation of a rotary evaporator for
maximum throughput requires continuous
monitoring by the user. Larger vessels can, with
appropriate adapters, be placed in a centrifugal
evaporator, however, the rate of evaporation is
typically a lot less than that achieved by a rotary
evaporator.
This paper details a new development which
enables a centrifugal evaporation system to
achieve evaporation speeds comparable to a
rotary evaporator.
