Congratulations on your purchase of a Labconco CentriVap DNA Centrifugal
Concentrator . Models are available for operation on 115V or 230V.
The CentriVap Concentrator uses centrifugal force with heat and vacuum to
rapidly dry precipitates of DNA and RNA 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 bench top or other laboratory work surface.
All wetted parts within the pump are PTFE, or other chemical resistant
fluoropolymers. A glass trap is provided to remove liquid from the system before
it enters the pump and a second glass trap is provided on the outlet side of the
pump to trap liquid expelled from the pump.
The microprocessor, which controls the operation of the heater and the motor,
provides excellent regulation and reproducibility of protocols. A manually preset
timer can signal the end of the run. Nine different protocols can be stored in
memory so exact test parameters can be easily repeated.
