Congratulations on your purchase of a Labconco CentriVap Refrigerated
Concentrator. Models are available for operation on 115V or 230V.
The CentriVap Refrigerated Concentrator, when combined with the CentriVap
Cold Trap, uses centrifugal force and vacuum with or without heat to rapidly
evaporate and condense solvents from biological and analytical samples.
Centrifugation eliminates bumping and foaming as vacuum is applied and also
concentrates the solute in the bottom of the vial. This allows recovery of solutes
from sample volumes as small as a few microliters. The unique advantage of this
concentrator is that it may be cooled to -4°C to prevent damage to heat labile
samples. For faster evaporation, the concentrator is equipped with a 300 watt
heater to warm the chamber during processing. The concentrator may be placed
on a benchtop or other laboratory work surface.
The microprocessor, which controls the operation of the heater and the motor,
provides excellent regulation and reproducibility of protocols. The end of the run
can be signaled by a manually preset timer. Nine different protocols can be stored
in memory so exact test parameters can be easily repeated.
As the companion to the Concentrator, the CentriVap Cold Trap protects the
vacuum pump by trapping moisture, vapors and corrosive fumes as they evaporate
from the samples.
