Congratulations on your purchase of a Labconco CentriVap Concentrator System.
Models are available for operation on 115V or 230V.
The CentriVap Concentrator, when combined with the CentriVap Cold Trap, uses
centrifugal force with heat and vacuum 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 concentrator is equipped with a 300 watt heater to speed
evaporation by warming the chamber during processing. A timed outlet for the
vacuum pump connection delays the start of the pump until the rotor reaches
operating speed. A safety switch prevents the concentrator from starting when the
lid is in the open position and a latch prevents the lid from being opened while the
rotor is turning. The compact, low profile design allows the concentrator to 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. The stainless steel trap is used for aqueous and organic
applications. For corrosive applications, the optional Glass Trap insert should be
used. The 230V 50Hz models comply with CE regulations.
