Chapter 2: Prerequisites
Vacuum Pump
Requirements
A vacuum pump must be provided by the user. A
vacuum pump with a free air flow rate of 113 liters per
minute and 0.2 x 10
-3
mbar blank off pressure is
adequate for aqueous samples. More volatile samples
can be satisfactorily processed using a diaphragm pump
with a free airflow of 42 liters per minute and 200 mbar
vacuum. The inlet fitting on the vacuum pump must be
suitable for 0.50 I.D. 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.
TO INSURE THAT AGGRESSIVE
SAMPLES USED IN THE
CENTRIVAP DO NOT DAMAGE THE
VACUUM PUMP, IT IS
RECOMMENDED THAT ALL
INTERNAL WETTED PARTS ARE
TEFLON®* OR TEFLON COATED.
CAUTION: When selecting the
vacuum pump it is very important to
consider the flammability of the
solvent that will be used. If the
solvents are flammable, an explosion
proof vacuum pump or one suitable
for the solvents to be processed is
recommended.
