System Overview
Principle and Intended Use
For in-vitro diagnostic use to produce the rapid separation of whole blood contained in original collection
tubes.
The Express 3 is a high-speed bench top centrifuge used to rapidly separate blood components in the
original sample collection tubes.
The eight-place 30° angle rotor included with the centrifuge produces rapid separation while minimizing
potential for re-suspension of cells. The operator selects a fixed spin time of 2, 3, or 5 minutes. The
rotation speed is fixed at 7200 rpm for the 2 and 3 minute cycles, producing a centrifugal force of 4440 xg
at a rotor radius of 7.65 cm.
The 5 minute cycle generates 2685 xg at 5600 rpm. This setting is intended for use with large glass
tubes (7mL and 10 mL), which require lower g-forces. Five minutes at 5600 rpm produces the same
degree of separation achieved with three minutes at 7200 rpm.
