4 Applications

4.1 Introduction

This section describes the use of specific rotors and
accessories. More detailed information is shipped with the
rotor or accessory itself. This section contains five
reference sections:

•

Speed and Force Tables

•

Derating Table for Dense Samples

•

Chemical Resistance Table

•

Decontamination Table

•

Nomograph

Caution:

Do

not

exceed maximum rated speed for each

rotor/accessory combination. Maximum rated speeds can
be found in Section 4.2 -

Speed And Force Tables

.

Relative Centrifugal Force

(RCF or G-force) at a given

speed varies with the rotor, and with the distance away
(rotating radius) from the shaft of the centrifuge (center of
rotation). The rotating radius is measured to the furthest

inside

tip of the tube, away from the centrifuge shaft. The

Speed and Force Tables indicate the maximum speed and
RCF that the 3000/3000R can achieve, with various
rotor/accessory combinations. The Derating Table
specifies reductions in maximum RPM, when spinning
samples with specific gravity above 1.2.
