Intended Use This centrifuge is a laboratory product used to separate substance mixtures of different densities. This centrifuge can become an In-vitro-diagnostics device (Directive 98/79/EC), if used together with the hematocrit rotor and his accessories. The hematocrit value is determined using the instructions written in the instruction manual of the hematocrit rotor. The instructions are based upon the reference method following DIN 58933, allowing to determinate the erythrocyte volume fraction within the blood. This centrifuge has to be operated by trained specialists only.

Precautions
Hazardous Substances f
WA R N I N G
Especially when working with corrosive samples (salt solutions, acids, bases), the accessory parts and vessel have to be cleaned thoroughly.
Do not centrifuge explosive or flammable materials or substances.
The centrifuge is neither inert nor protected against explosion. Never use the centrifuge in an explosion-prone environment.
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) and any local regulations. 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 contaminated the centrifuge or its parts, appropriate disinfection measures have to be taken (“Disinfection” on page 33).
Extreme care should be taken with highly corrosive substances which can cause damage and impair the mechanical stability of the rotor. These should only be centrifuged in fully sealed tubes.
If a hazardous situation occurs, turn off the power supply to the centrifuge and leave the area immediately.
Operating w
WA R N I N G
Never use the centrifuge if parts of its cover panels are damaged or missing.
Never start the centrifuge when the centrifuge door is open.
Do not move the centrifuge while it is running.
Do not lean on the centrifuge.
Do not place anything on top of the centrifuge during a run.
Never open the centrifuge door until the rotor has come to a complete stop and this has been confirmed in the display.
The emergency door release may be used in emergencies only to recover the samples from the centrifuge, e.g. during a power failure (see section “Mechanical Emergency Door Release” on page 37). Do not open the centrifuge, while it is running.
In any case of severe mechanical failure, such as rotor or bucket crash, the centrifuge is not aerosol-tight. In case of rotor failure the centrifuge can be damaged. Leave the room. Inform customer service.

3.
Check if the rotor is properly installed by lifting it slightly on the handle or from beneath the rotor. If the rotor can be pulled up, then it must be reconnected to the centrifuge spindle.
WA R N ING If the rotor cannot be properly locked in place after several attempts, then the Auto-Lock is defective and you are not permitted to operate the rotor. Check for any damage to the rotor and the spindle: Damaged rotors must not be used. Keep the centrifuge spindle area of the rotor clear of objects. If in doubt please call Thermo Fisher Scientific Customer Service.
C A U T I ON Check that the rotor is properly locked on the centrifuge spindle before each use by pulling it at its handle or from beneath the rotor. The rotor has to be locked tight.
4.
If available close the rotor with the rotor lid. Check the according rotor manual for further details on requirements and methods of closure.
C A U T I ON Be sure to check all sealings before starting any aeorsol-tight applications. See the information in the rotor instruction manual.
