• The rotor cover should not be applied nor should the rotor be loaded while it is mounted on
the centrifuge; doing so may damage the motor. Place the rotor on a tabletop to load
samples and apply the rotor cover.
• Never use underrated tubes or tubes that are of poor quality. Sample tubes must be
compatible with the Relative Centrifugal Force (RCF) rating of the centrifuge (see instruction
manual). Use only tubes that are rated at or above the g-level of the spin.
The fit of the sample tube within the rotor tube slot is critical. Use only sample tubes that are
shaped so as to be fully supported by tube inserts. Sample tubes have a limited life and should
be used as per the sample tube manufacturer's recommendations.
Never overload sample tubes. Most sample tubes are designed to be used with liquid
samples only. Do not load solid material into tubes.
Never attempt to centrifuge any liquid or substance having a homogenous density greater
than 1.2g/ml.
Never mix the sample tube type within a rotor. The weight of each sample should be within
5% of all other samples by weight. To maintain proper balance, place loaded sample tubes
into the into tube slots that are opposite each other.
Always use the rotor cover. The rotor cover is designed to minimize wind resistance on
the spinning rotor enabling it to achieve speed more quickly. Spinning without the rotor
cover may result in motor failure.
The rotor cover is not intended to be a bioseal (as defined by IEC 1010-2-020) for
containment of pathogenic microbiological specimens; however, it does provide an extra
layer of protection against contamination in the event of tube breakage.
Rotor Installation
• To install the rotor in the centrifuge: Center the rotor and push down until the rotor locks into
position. Spin the rotor by hand and check that it is flat and evenly spaced within the
chamber.
• The centrifuge must be located at least 300mm from the any bench edge. Never stand
within the safety zone of 300mm of a centrifuge during a spin. Wait until the rotor has
stopped spinning before opening the unit. Never attempt to open or move the unit while the
rotor is still in motion.
Rotor Use and Handling
• The rotor may be cleaned using methyl or isopropyl alcohol, soap solutions, heptane,
hexane, naptha or Freon ® TF cleaner. Do not use corrosive cleaning solvents with
partially halogenated hydrocarbons, such as 1,1,1 trichloroethane, phenol, methylene
chloride or ketones such as MEK.
• When necessary, the rotor and cover may be autoclaved at 115 kPa absolute pressure
(121ºC to 124ºC). Note: autoclaving decreases the usable life of the rotor. If the
rotors are autoclaved frequently (once a day) replace your rotors every 3 months. If
you autoclave your rotors more than once a day, please replace them after 60
autoclaving cycles
.
The use of IsoQuick ® brand nucleic acid extraction kits with this product is not advised. If the
IsoQuick ® extraction matrix or dye components come in contact with the Ultem ® rotor used in
the product, they may cause cracks or striations. Cracked rotors may disrupt during use. If any
IsoQuick ® brand components come in contact with the rotor in this product, immediately
replace the rotor. Please fully read the Rotor Usage Guide section of this manual to learn more
