7.1.3 Rotor, Buckets, and Multiple Carriers
Rotors, buckets, and multiple carriers are produced with highest precision, in
order to withstand the permanent high stress with high gravitational fields.
Chemical reactions as well as stress-corrosion (combination of oscillating
pressure and chemical reaction) can affect or destroy the metals. Barely
detectable cracks on the surface can expand and weaken the material without
any visible signs.
•
Check the material regularly (at least once a month) for
−
cracks
−
visible damage of the surface
−
pressure marks
−
signs of corrosion
−
other changes.
•
Check the bores of the rotors and multiple carriers.
•
Replace any damaged components immediately for your own safety.
•
Protect the rotors, lid seals, and rubber cushions (if included) at least once
per week with the supplied slushing oil (part no. 70104).
•
Grease the rotor tie-down screw with grease for load-bearing bolts (part no.
70284).
7.1.3.1 Microhematocrite Rotor
•
Remove the microhematrocrite rotor for cleaning.
•
Wipe the centrifuge chamber clean.
•
Replace the rubber ring in the event of wear or glass breakage (part no.
16003 for rotor 11024).
