Location and Exhaust Requirements
The CentriVap Concentrator should be located on a surface that is stable, flat and level.
WARNING: The CentriVap System should be located within a fume hood if
hazardous or flammable solvents are used. Heating of materials could lead
to the liberation of hazardous gases. In all cases, regardless of the solvent
used, it is strongly recommended that the vacuum pump is vented in a fume
hood. An accessory secondary trap is available to minimize the exhausting of
solvents into the atmosphere. This does not, however, negate the need to
exhaust the vacuum pump into a fume hood. Failure to properly vent the
CentriVap will expose personnel to potentially harmful chemicals.
The CentriVap Refrigerated Concentrator has not been evaluated by an
approval agency for the use of biological, radio toxins or flammable liquids
or materials.
Vacuum Pump Requirements
A vacuum pump must be provided by the user. A vacuum pump with a free air
flow rate of 90 liters per minute and 2 x 10
-4
mBar ultimate pressure is adequate
for aqueous samples. More volatile samples can be satisfactorily processed using
a diaphragm pump with a free airflow of 75 liters per minute and 2 mbar vacuum.
The inlet fitting on the vacuum pump must be suitable for 0.50 ID hose.
Vacuum pumps used with 115V models should be equipped with a 115V, 15 Amp
NEMA 5-15P plug. Vacuum pumps used with 230V models should be equipped
with a “reverse” IEC 320 plug. This will allow the vacuum pump to be plugged
into the receptacle on the back of the CentriVap.
IMPORTANT NOTE: To ensure that aggressive samples used in the
CentriVap Refrigerated Concentrator do not damage the vacuum pump, it is
recommended that all internal wetted parts are PTFE or PTFE coated.
