Operation
Planning
Thoroughly understand procedures and the equipment
operation prior to beginning work. The unique performance of
the SRF110 is dependent upon the proper balance of heat,
vacuum and centrifugal force. If the proper balance is not
established, it is possible to damage or lose a portion of the
sample. Therefore, if you are unfamiliar with the SRF110 or
are attempting a new protocol, it may be helpful to make a
trial run that is void of the sample you are attempting to
concentrate.
Sample Format Selection
Normally, sample tubes should be filled no more than
approximately half full. Select the size of the sample tube so it
is compatible with the rotor and the desired sample size.
Tubes should not be excessively loose in the rotor. Rotors are
available with holes for various size tubes.
Loading Sample Format into
the SRF110
Smooth operation of the SRF110 is dependent upon proper
balance of the machine. Therefore, if less than a full load of
samples are run, it is important to load samples into the
SRF110 in a symmetrical manner distributing the weight of
the samples evenly in the sample rotor.
Temperature Setting
Guidelines
The evaporation rate achieved by the SRF110 is dependent
upon a variety of factors. These include the nature of the
solvent, the temperature and the pressure in the vacuum
system.
Time Setting Guidelines
The Refrigerated SRF110 allows two different temperatures to
be programmed for user specified periods of time. If
sequential temperatures are not desired, set Time at "2" to
"0". When both programmed times expire, the rotor will stop,
the heater and refrigeration systems shut off. An alarm
sounds until any control button is pressed.
