This section provides a brief physical and functional description of the
Beckman Coulter Allegra 21 series, GS-15 series, and Spinchron 15
series centrifuges. The operating controls and indicators are also
described; instructions for their use are in Section 3. Chemical compati-
bilities of materials listed in this manual can be found in Chemical
Resistances (publication IN-175). Refer to the applicable rotor manuals
for rotor descriptions.
INSTRUMENT FUNCTION AND SAFETY FEATURES
INSTRUMENT FUNCTION
The Beckman Coulter Allegra 21 series, GS-15 series, and Spinchron 15
series compact benchtop centrifuges generate centrifugal forces required
for a wide variety of applications. Together with any of several Beckman
Coulter rotors designed specifically for use in these centrifuges, the instru-
ment applications include:
• Routine processing such as sample preparations, pelleting, extractions,
purifications, concentrations, phase separations, receptor binding, and
column centrifugations.
• Processing large numbers of small-volume samples in multiwell plates
for concentrating tissue-culture cells, cloning and replicate studies,
in-vitro cytoxicity studies, receptor binding, and genetic engineering
experimentation.
• Rapid sedimentation of protein precipitates, large particles, and cell
debris.
• Binding studies and separation of whole blood.
• Cell isolation.
