Heraeus Pico 17 / 21
Thermo Scientific
Please pay particular attention to the following aspects:
• Location: well-ventilated environment, set-up on a level and rigid surface with adequate
load-bearing capacity.
• Rotor installation: make sure the rotor is locked properly into place before operating the
centrifuge.
• Especially
when working with corrosive samples (salt solutions, acids, bases), the
accessory parts and vessel have to be cleaned carefully.
• Always balance the samples.
Centrifuging hazardous substances:
• Do not centrifuge explosive or flammable materials or substances which could react
violently with one another.
• The centrifuge is neither inert nor protected against explosion. Never use the centrifuge
in an explosion-prone environment.
• Do not centrifuge inflammable substances.
Remaining risk: Improper use can cause damages, contamination, and injuries
with fatal consequences.
• Do not centrifuge toxic or radioactive materials or any pathogenic micro-organisms
without suitable safety precautions.
When centrifuging microbiological samples from the Risk Group II (according to the
Bio-safety Manual" of the World Health Organization (WHO)), aerosol-tight biological
seals have to be used.
For materials in a higher risk group, extra safety measures have to be taken.
• If toxins or pathogenic substances have gotten into the centrifuge or its parts,
appropriate disinfection measures have to be taken (see “Disinfection” on page 5-3).
Remaining risk: Improper use can cause damages, contamination, and injuries
with fatal consequences.
• Highly corrosive substances which can cause material damage and impair the
mechanical stability of the rotor, should only be centrifuged in corresponding protective
tubes.
