2.General warnings
Only authorized personnel can use this centrifuge. The user must go through the instructions and
understand every aspect before using this machine. In case of malfunction, contact the supplier.
This centrifuge must not be placed inside another unit or electrically or mechanically connected to
another unit. Only the rotors and accessories supplied with this centrifuge and by this manufacturer
should be used with this machine. Check that they are not damaged before each use. The rotors and
accessories of this centrifuge must not be used on centrifuges of other brands and viceversa.
Do not place flammable samples, chemicals with exothermic properties, explosive or highly reactive
substances for centrifugation inside this centrifuge.
No person other than those authorized by the manufacturer is authorized to make modifications to
the centrifuge after shipment from the factory.
In case of any damage to the unit or in the presence of abnormal noises or anomalies, stop the use of
this centrifuge and immediately report the fault to the supplier.
In case of liquid spills, disconnect the device from the power supply and thoroughly clean the device
and accessories, following the cleaning and disinfection instructions given in the instruction’s manual.
Never attempt to override the safety systems and / or work with the centrifuge lid open.
Give particular attention when using dual sand witch tubes with internal filters, when the filter
porosity is not similar in the tubes, it can lead to unbalance at high speeds thereby causing irreparable
damage to the machine.
When opening and closing the lid, do not grasp the part between the lid and the centrifuge, do not
insert your fingers into the centrifuge closure and do not grasp the lid locking mechanism, this could
cause physical damage.
Make sure that the centrifuge lid opens completely and remains in the open final position. Regularly
check that the gas spring works perfectly. In case of malfunction, contact the supplier's technical
service.
In case of emergency lid release, the rotor could continue rotating for a few more minutes.
Check through the peephole in the lid that the rotor has stopped before intervening on the
"emergency opening".
When changing the rotor, the power supply must be disconnected. This operation must be carried out
by qualified personnel.
The tubes must always be weighed complete with contents and caps.
Place the tubes symmetrically before starting centrifugation. Use only metal buckets suitable for the
type of rotor used and tubes suitable for adapters used. Use only tubes that have been approved by
the manufacturer with the desired g (rcf) values. Do not use fragile or deforme tubes.
The centrifuge is designed for centrifuging substances with a maximum density of 1.2 g / ml, at
maximum speed and at maximum volume filling / load. Do not exceed the maximum rotor load.
Never use chemicals or cleaners which could be naturally corrosive. This could cause damage to the
centrifuge. Use a dry cloth to clean the inside of the chamber.
The interior of the chamber must be cleaned and checked regularly for contamination.
In case of continuous use of the refrigerated models, turn off the centrifuge regularly to let the ice
melts, remove any deposits and condensing formation using a soft and absorbent cloth. This is useful
for decreasing icing and compressor overheating during cooling.

•Biological safety
During operation, the centrifuge can generate particles suspended in the air. Since these NEYA 8/10/16 models are
not refrigerated centrifuges therefore they do not have a completely sealed chamber. This type of ventilated
centrifuge helps to reduce the excess heat created by the friction of the rotor with air in the internal chamber,
while the Neya 10R / 16R refrigerated models have a totally sealed chamber. To minimize the risks of aerosols
coming into direct contact with the person, always use tubes with biosafe lids. Glass tubes, if used, should not be
filled to the top to avoid spilling of liquid. Also, since the lid on the top has a gasket, you must make sure that this
gasket is not damaged. As it prevents direct exposure of the user with the sample. It is also advisable to open the
centrifuge lid 3 minutes after the centrifuge has stopped. This will give the particles time to disperse into air.
Bioseals (biological seal) is a part of biological safety systems, which are unable to guarantee the safety of people
and the environment when handling pathogenic microorganisms or infectious liquids. When working with
pathogenic organisms or infectious liquids of a high-risk group, more than one aerosol-tight seal must be provided.
If liquids are spilled into the chamber or into the rotor housing, the centrifuge must be thoroughly and entirely
cleaned by specialized personnel. In case of contact with infectious liquids and pathogenic germs, comply with
national regulations, the biological safety level of your laboratory, the safety data sheets and the manufacturers'
instructions for use. Wear personal protective equipment’s.
•Safety and/or protection devices
•Safety lid interlock to prevent lid opening during centrifugation.
•Detection of unbalances and stop of centrifugation with display error.
•Emergency unlocking of the lid.
