Rotors, adapters, buckets and rubber seal
Use neutral cleaning solutions (alcohol or alcohol-based
disinfectant) and a soft cloth to clean your rotors and
accessories. Wipe contaminated parts with neutral agents
for cleaning and disinfection (e.g. diluted neutral alcohol-
based disinfectant or 70 % isopropanol mixture). Use a
soaked gauze or lint-free cloth.
In case of spilling some aggressive liquid on your centrifuge
equipment, please clean it immediately. If there is stubborn
stain, clean with a plastic scrub pad and rinse equipment
with distilled water. Avoid immersing the rotor in water as liquid could flow into rotor cavities, and dry thoroughly with
a soft cleaning cloth.
As salt crystals located on metal surface will corrode the
surface, we strongly recommend cleaning rotors and buckets
immediately. If there is a need to clean the rotor’s tube cavities
or boreholes, use a stiff test-tube brush that has end bristles
and a non-metallic tip.
For swing-bucket rotors, ensure that the grooves in which
the buckets are fitted are free of contamination. Take care to
ensure that the buckets can still swing freely.
Figure 4: Clean rotor and rotor bores with plastic scrub pad and/or stiff test-tube brush in case of stubborn stain. Then rinse with water and dry.
After decontamination the equipment should be wiped with
distilled water. If needed, autoclave rotor, rotor lids and
buckets as recommended by the manufacturer. Never use
UV, beta, gamma radiation, or any high-energy radiation
source. Place parts on dry cloth upside down to dry (Fig. 4). Alternatively dry rotors, rotor boreholes and accessories
with absorbent towels. To prevent aerosol-tight lids/caps
and seals from getting worn out/damaged, store lids/caps
separately from the bucket/rotor.
Caution:
Do not use acetone, caustic detergents, or detergents that contain chlorite ions. Corrosion is most frequently
caused by using chlorite ion solutions, such as sodium hypochlorite (household bleach). Do not use steel wool,
wire brushes, abrasives, or sandpaper, since they may damage the rotor coating (anodized coating) and thus
increase the risk for corrosion. We do not recommend usage of
dishwashers for rotors or lids due to the
aggressive cleaning agents used in these devices. These agents may result in corrosion.
