• Using incorrect rotors & wrong spare parts will void the warranty.
• Centrifuge may be used for the specified applications only. It must not be operated in a hazardous or flammable environment and must not be used to centrifuge explosive or highly reactive substances.
• If liquids are spilled on the rotor or rotor chamber, the centrifuge must be cleaned carefully and properly before being used again.
• Prior to centrifugation, the tubes should be visually inspected for material damage. Damaged tubes may not be centrifuged. This is because broken ffi tubes can, in addition to sample loss, create imbalance which can result in further damage to the centrifuge and accessories.
• The capacity of 24 capillary tubes must not be exceeded as it is the maximum capacity.
• Do not lean on the equipment. It may damage the equipment or the harm the operator.
• When moving the centrifuge from a cold room to a normal room, run the centrifuge for 30 minutes beforehand in the cold room to avoid condensation. Alternately, allow it to warm up in the lab for at least 3 hours before use, but do not plug in the centrifuge in order to prevent possible damage by condensation.
• Be sure to close the tubes lid tightly prior to centrifugation. Open tubes lid can be torn off during centrifugation and can damage the rotor lid or centrifuge.
• Rotors and rotor lids are high-graded components which are subject to extreme mechanical strain. Even slight scratches and tears can lead to serious internal material damage. Ensure to check the rotor for any signs of damage before use. Rotor & rotor lid showing visible signs of corrosion or mechanical damage should not be used, contact your local supplier or mfg for replacement rotor & parts.
• Do not fill tubes while they are in the rotor. Liquid spillage may harm the device.
• In the event of contamination caused by aggressive agents, the rotor must be cleaned immediately using a natural cleaning liquid (like water). This is particularly important for the bores of the tubes. If any damage is seen, contact the service technician.
•  Before using cleaning or decontamination methods, other than those stipulate by the manufacturer, contact the manufacturer to ensure that the intended method will not damage the centrifuge.
• The power adaptor given with centrifuge unit is designed to use for that particular centrifuge. Do not use any other power adaptor, using any other power adaptor may damage the centrifuge and will void the warranty.
