1 Introduction
1.1 General Product Description
Marathon series units are
centrifuges, used in medical, industria
applications.
The Marathon 21000 Series is available in two models:
ventilated (21000) and refrigerated (21000R). Sections of
this manual that apply to the refrigerated version will be
designated 21000R or refrigerated only.
Both models accommodate swinging bucket or fixed angle
rotors. They can process a variety of tubes, bottles, and
microsample tubes. Swinging bucket styles include a 4 x
250 mL or microplate carrier rotor. The microplate rotor
can process both standard
angle styles include a 6 x 85 mL, an 8 x 28 mL or a
microtube rotor.
Each
centrifuge has an easy to use front panel that provides
two modes of operation:
