12. Press "STOP" to terminate operation if the SRF110 has
not already stopped itself.
13. When the evaporation is complete, allow the rotor to stop
moving, lift the lid and remove the samples.
General
During the run, display shows actual parameters. To check
set parameters, press View button and Enter button. The
display will revert temporarily to the set points for
approximately 5 seconds.
Cycle Interruption
At any time during a run, the cycle may be stopped by
pressing the "STOP" button. This shuts off all operating
functions. After the rotor stops, the lid may be opened. If it is
necessary to restart the SRF, close the lid and press "RUN."
The SRF resumes operation at the same set point parameters
and the timer continues to count down from the time at which
the SRF was stopped.
Safety Precautions
Special precautions must be observed if the samples used in
the SRF110 Concentrator are known to be hazardous, toxic,
radioactive, or contaminated with pathogenic
microorganisms. These actions should include but are not
limited to the following:
•
Refer to the World Health Organization Laboratory
Biosafety Manual, paying special attention to information
about centrifuges and the handling of hazardous
materials.
•
Operate or vent the SRF110 Concentrator inside a
suitable fume hood or ventilation device. Load rotors in a
ventilation device.
•
Periodically inspect all parts of the SRF110 Concentrator
including the lid, gasket, chamber, plumbing components
and rotors.
10 | Operation
Location & Exhaust
WARNING: The SRF110 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 SRF110 will expose
personnel to potentially harmful chemicals.
The SRF110 Refrigerated Concentrator has not been
evaluated by an approval agency for the use of biological,
radio toxins or flammable liquids or materials.
WARNING: Solvents used in the SRF110 can
cause skin, eye, respiratory and digestive
system disorders. Locate the SRF110 inside
fume hood.
Emergency Access into
the Chamber
The cover must be closed before beginning a run. The run will
start after closing the cover and pressing the "Run/Start"
button. Cover closure can be ensured by latch sound.
During a run the user cannot open the cover due to vacuum in
the concentration chamber. The cover is locked down always
during a run and whenever power to the unit is interrupted.
The cover lock is an additional safety feature that reduces the
risk of injury or damage while rotor is spinning. Never bypass
the cover lock mechanism during a run.
The SRF110 is designed to prevent access to the chamber in
the event of a power disruption. If it is necessary to open the
lid when there is no electrical power connected to the
SRF110, insert a small screwdriver or similar instrument into
the small round hole on the left side of the case behind the
control panel. This will unlock the lid latch mechanism. While
holding the screwdriver in place, raise the lid with the other
hand.
CAUTION: Never attempt to defeat the latch or
open the lid while the SRF110 is running.
Personnel injury can result from moving parts and
chemicals.
