| To process large series of samples efficiently
requires fast, variable, reproducible, gentle and environmentally-friendly
handling of the samples. Whether you use methanol, water or less volatile
solvents such as dimethylformamide (DMF) or dimethylsulfoxide (DMSO),
the CombiDancer is the ideal solution for your
laboratory.
The evaporation of solvents is an important part of sample preparation,
e.g. for solid phase extraction in the analytical laboratory, in
combinatorial chemistry, high throughput screening, and when employing
new technologies.
The operating principle of the CombiDancer
involves a combination of heating, vortexing, and vacuum. Vortexing
has various advantages over centrifuging. It enlarges the evaporation
surface and distributes the heat evenly in the sample. There is
no compression of the vapour phase. The CombiDancer
can work with any vacuum pump available. However, we recommend
the Vacuubrand PC 2003 VARIO diaphragm pump.
The samples are heated by infrared lamps. An independent compartment
heater prevents the condensation of solvents with high boiling point
in the vacuum chamber. The actual temperature can be measured directly
in the sample by means of a PTFE-coated temperature sensor. All
parameters can be programmed and controlled separately.
