Preface
Thermo Scientific Sorvall ST 8 Centrifuge 13
WARNING
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.
• Do not centrifuge toxic or radioactive materials or any pathogenic micro-organisms
without suitable safety precautions.
If centrifuging any hazardous materials mind the „Laboratory Biosafety Manual“ of the
World Health Organization (WHO).
When centrifuging microbiological samples from the Risk Group II (according to the
"Laboratory Biosafety Manual" of the World Health Organization (WHO)),
aerosol-tight biological seals have to be used.
Look on the internet page of the World Health Organization (www.who.int) for the
„Laboratory Biosafety Manual“.
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 48 ).
•
Highly corrosive substances which can cause material damage and impair the
mechanical stability of the rotor, should only be centrifuged in corresponding protective
tubes.
Remaining risk: Improper use can cause damages, contamination, and injuries
with fatal consequences.
Remaining risk: Improper use can cause damages, contamination, and injuries
with fatal consequences.
Note If used for Foodstuffs machinery, for cosmetics or pharmaceutical products, only use closed
or aerosol-tight containers for centrifugation.
