Introduction & Description SORVALL ® Centrifuges

Specific RC3BP™ features include:
• An optional Network Computer Interface Package, which
includes WatchLog Network™ software, allows automatic
computerized logging of centrifuge QC RUN and production
run data via RS485/RS232 communication hardware.
• QC RUN feature allows simple, automatic speed/temperature
verification (optional Computer Interface Package required).
• A user-friendly, easy to clean control panel with an interactive
LCD SET display, option selection indicators, and a large LED
RUN display for across-the-room viewing.
• STEP RUN capability allows the linking-together of up to three
sets of run parameters to automatically perform innovative step
run protocols. The step run sequences may be saved in program
memory for simple recall in future use.
• Programming capability allows saving (to a battery backed-up
memory) of up to 9 sets of run parameters plus 6 step run se-
quences, allowing simple recall and error-free run reproducibility.
The SAVE RUN sequence alerts users before overwriting
programs, to eliminate inadvertent loss. A convenient RECALL
key allows access to saved parameters for selection or reference.
• KEYPAD LOCK, a 3-position keyswitch with a removable key,
that is designed to limit control panel access. Besides allowing
full functionality, the keyswitch can be set so that run parameters
cannot be changed, or so that only parameters from program
memory may be run – in either case, greatly reducing the chance
for operator error or unauthorized changes.
• Run duration controlled by TIME (minutes:seconds), by HOLD
(for continuous runs), or by Accumulated Centrifugal Effect™
(ACE). Because rotor load differences, fluctuations in voltage,
or slight mechanical differences affect how quickly centrifuges
reach set speed, ACE calculates the effect of speed in relation to
time, and adjusts run duration to account for differences in
acceleration, thereby improving separation consistency and run
reproducibility – run after run, from centrifuge to centrifuge.
• Rotor SPEED controlled by RPM (revolutions per minute), or by
the RCF (relative centrifugal force, or
g -force) of the rotor selected.
• Automatic sample temperature calculation considers the rotor,
run speed, run time, set temperature and measured chamber
temperature to estimate and maintain sample temperature.
• SLOW START chooses gentle acceleration from 0 to 250 rpm (at
250 rpm, acceleration transitions to the normal, maximum rate),
with the slow start rate defined by the selection of one of ten
different acceleration profiles.
