Please pay particular attention to the following aspects:
•
Location: well-ventilated environment, set-up on a level and rigid sur-
face 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.
When centrifuging microbiological samples from the Risk Group II
(according to the "Laboratory 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 6-4 ).
• Highly corrosive substances which can cause material damage and
impair the mechanical stability of the rotor, should only be centri-
fuged in corresponding protection tubes.
IF A HAZARDOUS SITUATION OCCURS, TURN OFF THE
POWER SUPPLY TO THE CENTRIFUGE AND LEAVE THE
AREA IMMEDIATELY.
Normal use
The centrifuge is to be used for separating materials of different density
or particle size suspended in a liquid.
