For information on the maintenance of rotors and tubes, see the rotor instruction manual provided

with the rotor.

Rotor chamber

To maintain the rotor chamber, follow the instructions given below:

1. When the micro-ultracentrifuge is not in use, keep the rotor chamber ventilated.

2. If the bowl is moist, wipe it with a clean, dry cloth or sponge.

3. If the rotor chamber is dirty, wipe it with a clean cloth wrung out in a diluted solution of a mild,

non-alkaline detergent. For sterilization, wipe it with a cloth etc. dampened with 70% ethanol.

This drive shaft is very important because the rotor is mounted on it and the drive shaft transmits

motor torque to the rotor. Before mounting a rotor, wipe the outer surface of the drive shaft with a soft

cloth dampened with water.

Always keep the top deck and the cabinet of the micro-ultracentrifuge clean to prevent dust and other

materials from falling into the rotor chamber. Wipe the top deck and the cabinet with a cloth or sponge

dampened with a diluted solution of neutral detergent. If any solution that is toxic, radioactive, or

pathogenic is spilled inside or outside the micro-ultracentrifuge, take necessary action according to

your proper laboratory procedures and methods.

If the door seal O-ring is dusty or scratched, high vacuum level will not be obtainable. Always keep the

door seal O-ring clean. When the micro-ultracentrifuge is used frequently, take out the door seal

O-ring and wipe it with a clean, soft cloth and then put a thin coat of vacuum grease on it every three

to four months (ordinarily, once a year). If the door seal O-ring is damaged, replace it. Wipe the groove

for the door seal O-ring with a clean, soft cloth dampened with alcohol or a similar solvent.

CAUTION 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.

CAUTION Clean the inside of the drive hole of the rotor and the surface of the drive shaft

of the micro-ultracentrifuge once a month. If the drive hole or the drive shaft is stained or

any foreign matter is adhered, the rotor may be improperly installed and come off during

operation.
