products.
* Speed in revolutions per minute (rpm) is related to angular velocity,
ω
, according to the following:
ω
= (rpm) = (rpm) (0.10472)
Where
ω
= rad/s. All further references in this manual to speed will be designated as rpm.
Centrifuge Description
The SORVALL
®
RC12BP™ is a microprocessor controlled, high-
capacity lowspeed refrigerated centrifuge designed for use in regu-
lated environments (such as those found in blood banking, biotech-
nology, or pharmaceutical arenas). The control panel, designed to be
easy to use and easy to clean, allows simple input through a positive-
feedback keypad with visual verification of set parameters and current
run conditions. The control panel also prompts users for correct entry
and displays user messages. The control panel introduces automation
of quality control runs, an optional computer interface package
enables automatic, on-line, quality control run and production run
data logging.
The RC12BP™ operates at speeds* up to 4700 rpm, and is capable of
producing relative centrifugal force up to 7333g. It uses a balanced,
high-torque brushless dc motor designed to deliver optimal
performance with smooth, quiet operation over its full speed range,
with long bearing life. Advanced capabilities of this motor offer
precise control of acceleration and deceleration, regardless of rotor
load, for exceptional run reproducibility. Directly connected to the
motor is a heavy-duty gyro-action drive with a square spindle that
accepts the SORVALL
®
H-12000 high-capacity swinging bucket
rotor. A viewing port in the chamber door permits speed confirmation
using an optical tachometer.
Precise temperature control is made possible by a refrigeration system
that is capable of delivering both cooling and heating. The high-
capacity system is charged with environmentally-friendly CFC-free
refrigerant. The microprocessor-controlled system consists of a low-
temperature evaporator, a hermetically-sealed thermally-protected
compressor, and a fan-cooled finned condenser.
