Glossary
ARC Automatic Rate Contr ol. An accessory
mode that controls the acceleration and
deceleration of a rotor to avoid gradient or
pellet disturbance. Automatically sets the
optimal acceleration and deceleration rate
for each rotor.
HOLD A feature that selects a continuous run
in place of a run controlled by time in hours
and minutes; when it is selected, HOLD
keeps (holds) the rotor at the selected run
speed until STOP is pressed.
Integrator Mode An accessory mode that
allows the user to control a run by an integral
value rather than time in hours and minutes.
The integral value represents the centrifuge
force accumulated over time. The mode is
activated by setting the OFF/
∫ω
2 dt to
∫ω
2 dt .
Normal Mode The operation mode that is
used to perform most centrifuge runs. The
mode is activated by turning the key on the
front panel to NORMAL and the OFF/ARC
switch and the OFF/
∫ω
2
dt switch to OFF.
Overtemperature The maximum estimated
sample temperature (MAX) allowed during
a centrifuge run; if the temperature in the
display exceeds this value, the run will
terminate.
RCF
Relative Centrifugal For ce. An accessory
that calculates RCF. The force ( g force)
applied to a suspension of particles during
centrifugation relative to the force that the
earth's gravity would have on them. It is
related to speed (rpm) by this equation:
RCF = 1
1.17 x radius (in cm) x (rpm
÷
1000)
2
.
Rotor Code
The number assigned to each
rotor model compatible with the centrifuge.
The code determines how the centrifuge
calculates RCF and controls speed and
temperature for the rotor.
Zonal Mode An accessory mode that allows
the user to dynamically load the SORVALL ®
TZ-28 Zonal Rotor. The mode is activated by
turning the key on the front panel to ZONAL.
