Description
AVAILABLE ROTORS
The following Beckman Coulter rotors can be used in the Allegra 25R centrifuge. The rotors are described
in individual manuals that accompany each rotor.
* Maximum speeds are based on a solution density of 1.2 g/mL.
† Relative Centrifugal Field (RCF) is the ratio of the centrifugal acceleration at a specified radius and speed (
r
ω
2
) to the standard acceleration of
gravity (
g
) according to the following formula:
where
r
is the radius in millimeters,
ω
is the angular velocity in radians per second (2
π
RPM /60), and
g
is the standard acceleration of gravity
(9807 mm/s
2
). After substitution:
