Chapter 1
INTRODUCTION
CENTRY™ 103 Minicentrifuge is an easy of use and portable benchtop device ideal for a
quick separation of particles from a supernatant according to a density gradient.
It also enables a spin down of a drop of liquid from the walls of tubes.
Equipped with robust and easy to change rotors, the CENTRY 103 Minicentrifuge can be
used either with microtubes or tube-strips. The round rotor has a capacity of eight
1.5 mL or 2.0 mL microtubes, and the rectangular shaped rotor capacity is two lines of
eight connected 0.2 mL tube-strips.
Due to its small footprint and a battery compartment, the CENTRY 103 Minicentrifuge
can be used anywhere, from small benches to laminar flow cabinets, or even if there is no
power supply available, the Minicentrifuge is convenient and easy to transport.
To start or stop centrifugation, simply press down in the lid.
The CENTRY 103 Minicentrifuge will automatically decelerate to a stop after six minutes of
continuous spinning.
