Hettlab AG - CombiDancer Infrared Vortex Evaporator

The compact solution you have always looked for !!!
To process large series of samples efficiently requires fast, variable, reproducible, genlte and environment-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 task during 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 is 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.

Vortexing:

• No balancing of the samples
• No compression of the gas phase
• no rotating parts

Heating:

• Heating of the sample surface
• Independent compartment heater
• Measurement of sample or rack temperature

Vacuum:

• Automatic vapour sensor
• No hysteresis
• Controllable pump frequency

For high volume routine operation a wide variety of sample racks are available. The CombiDancer racks are designed to accommodate most various kinds of customary sample tubes and up to four deepwell plates. All racks are made of anodized aluminum. Racks can be customized to fit your specific tube or combination of different sized tubes.
