In the centrifuge, disinfectants and cleaning agents generally used in medical care should be used (e.g. Aerode-
sina-2000, Lysoformin 3000, Melseptol, Melsept SF, Sanepidex, Cutasept F).

9.3.1 Autoclaving

• Rotors, buckets and round carriers can be sterilized in autoclave with temperature 121°C during 20 min (215
kPa), unless otherwise specified in the OPTIONAL ACCESSORY.
• During sterilization (autoclaved) by means of steam one should to consider temperature resistance of individual
materials.
• Deformation of the accessories (carriers or lids made of plastic) may occur during autoclaving.
• Do not autoclave disposable materials (e.g. tubes, cyto-container).
• The life of the accessory depends on the frequency of autoclaving and use.
• Autoclaving reduce lifespan of plastic and mechanical components. PC tubes can become useless.
• Pressure in closed containers can cause plastic deformation or explosion.
• Prior to autoclaving the rotors and accessories, thoroughly wash and rinse with distilled water.
• Never exceed the permissible autoclaving temperature and time.
• If you want to keep the hermetic seals, replace the sealing rings after each autoclave.
