CAUTION
• Position the micro-ultracentrifuge on a level surface, such as a table or laboratory bench
that can support the weight of the micro-ultracentrifuge and resist vibration.
• Be sure to remove the rotor from the rotor chamber when micro-ultracentrifuge is not
used for a long time or when the machine is moved. Otherwise the drive shaft (crown)
may be damaged.
• Before using a rotor, be sure to read through the rotor instruction manual.
• Check the chemical resistance chart attached to the rotor, and do not use any sample
inapplicable to the tubes, tube caps, bottles, or bottle caps, etc. Using such a sample could
corrode or deteriorate such parts.
• Use the rotor tubes and bottles within their actual capacities.
• Mount the rotor onto the drive shaft gently and properly.
• Do not drop the rotor or apply excessive force to the drive shaft to avoid damage to the
drive shaft.
• Maximum rotor speed depends on the tubes or adapters to be used. Follow the
instructions on the rotor instruction manual.
• This micro-ultracentrifuge might convey vibration to a table while the rotor is rotating.
If a measuring device is positioned on a table and near this micro-ultracentrifuge, use a
measuring device carefully.
• Approximately even quantities of sample in the tubes are sufficient for balancing, and
extremely different sample quantities must be avoided (Refer to
and rotors" on page 2-3 for the sample balancing).
• Clean the inside of the drive hole (crown hole) of the rotor and the surface of the drive
shaft (crown) of the micro-ultracentrifuge once a month.
• When storing the rotors on a shelf, take appropriate safety measures in areas prone to
earthquakes
• Do not pour any solution such as water, detergent, or disinfectant directly into the rotor
chamber and be careful not to spill the sample into the rotor chamber. If you do so, the
bearings of the drive unit might corrode or deteriorate and it might cause vacuum failure.
• Do not operate the display panel (Touchscreen) using a ball-point pen.
DANGER
• Before removing the cover, top deck, or other component for maintenance, always turn
off the POWER switch of the instrument, unplug the power cord from the wall outlet,
and wait at least three minutes to avoid the risk of electrical shock.
WARNING
• For maintenance and repairing of the rotors, tubes, etc., see the rotors and tubes
instruction manual.
• After installation and before any test-run, this micro-ultracentrifuge always needs the
internal check by a Thermo Fisher Scientific authorized sales/service representative.
• Repairs, disassembly, and other modifications to the micro-ultracentrifuge are strictly
prohibited unless performed by a Thermo Fisher Scientific authorized sales/service
representative.
