
When centrifuging hazardous substances or mixtures, which are toxic, radioactive or contaminated with
pathogenic microorganisms, suitable measures must be taken by the user.
Fundamentally, centrifuge containers with special screw closures must be used for hazardous substances. For
materials of risk groups 3 and 4, in addition to sealable centrifuge containers, a bio-safety system must be used
(see the "Laboratory Bio-safety Manual" from the World Health Organization).
In a bio-safety system, a bio-seal (sealing ring) prevents droplets and aerosols from escaping.
If the hanger of a bio-safety system is used without the lid, the sealing ring must be removed from the hanger to
prevent damage to the sealing ring during the centrifugation run.
Damaged bio-safety systems are no longer microbiologically sealed.
If a bio-safety system is not used, a centrifuge is not microbiologically sealed for the purposes of the standard EN
/ IEC 61010-2-020.
When closing a bio-safety system, follow the instructions in the chapter "Closing biosafety systems".
For the available bio-safety systems, see the chapter "Appendix, Rotors and accessories". If in doubt, you can
get the information you need from the manufacturer.
 The centrifuge must not be operated with highly corrosive substances which could impair the mechanical integrity
of rotors, hangers and accessories.
 Repairs must only be carried out by personnel authorised to do so by the manufacturer.
 Only original spare parts and original accessories licensed by the Andreas Hettich GmbH & Co. KG company are
allowed to be utilised.
 The following safety regulations apply:
EN / IEC 61010-1 and EN / IEC 61010-2-020 as well as their national deviations.
 The safe operation and reliability of the centrifuge can only be guaranteed if:
 the centrifuge is operated in accordance with the operating instructions,
 the electrical installation on the site where the centrifuge is installed conforms to the demands of EN / IEC
stipulations.
 Meeting the country-specific requirements concerning occupational safety with regard to the use of laboratory
centrifuges at the workplaces provided for this purpose by the user is the responsibility of the user.
