Use only the rotors and accessories authorized by the manufacturer See 2 4 Accessory tables Balance the rotor For swing out rotors always puts all the buckets and inserts even empty in their dedicated location Respect the maximum density of 1 2 g ml particularly when using maximum speed Limit the volume if the density is exceeded 2 7 2 Actions forbidden during centrifugation It is forbidden to centrifuge the following material Inflammable or explosive material Material that could react chemically with sufficient force to create danger The centrifuge is not designed to operate in an explosive environment It is forbidden to centrifuge toxic or radioactive material or material contaminated by pathogenic microorganisms in containers that are not sealed against aerosols and if necessary radiation It is forbidden to use rotors and accessories having exceeded the maximum usable lifetime of 10 years or 35 000 runs 1 in normal use condition amp maintenance or showing signs of wear traces of corrosion or mechanical faults 1 On 1st of 2 terms expired OMO205 Rev 1 March 2012 Best Products Best Performance Best Protection Page 11 of 35 NuAire Inc 2100 Fernbrook Lane Plymouth MN 55447 U S A ph 763 553 1270 fx 763 553 0459 tf 800 328 3352 www nuaire com 3 DESCRIPTION OF THE CENTRIFUGE 3 1 General view Ventilated model 3 2 Controls and Display ssawel centri
4. Check the mounting and balancing of the rotor before starting this centrifugation run Take care to maintain and check the accessories See section 7 Keep the centrifugation chamber clean and dry Check that bottles and tubes can withstand centrifugation chemical resistance to the products centrifuged and mechanical resistance to the centrifugal force applied to them o When moving the centrifuge from a cold environment to a warmer environment condensation can form inside the centrifuge Leave the centrifuge to warm up for three hours before use o If the centrifuge is used in a manner not specified in the present manual the protection provided by the equipment may be impaired O O O O O O O 2 7 Correct use Laboratory centrifuges are used to separate substances of different densities by the application of centrifugal force In particular they enable biological samples to be prepared and treated before analysis within the framework of in vitro diagnostics Centrifuges are designed for interior use by personnel trained to use them 2 7 1 Practical notes on centrifugation Check that the centrifuge is stable and horizontal Check that the rotor is correctly fitted before starting a centrifugation run Check that tubes can resist the maximum centrifugal force applied see 2 4 Accessory tables Check that tubes are in good condition eliminate damaged tubes During operation the centrifuge must not be moved or knocked
5. This precaution will extend the life of metallic accessories Swing out rotors Check the greasing of the pins on which the buckets swing Replace this regularly at least once per month in order to ensure that the buckets swing freely Spread on a little grease by hand WARNING Failure to grease correctly could create an imbalance related to one or more buckets not swinging Use Food quality grease only 7 3 Storage of accessories Never leave a wet or moist rotor on a metallic surface even stainless steel risk of corrosion Unused rotors and accessories should be placed on a non metallic grid with pockets openings pointing downwards in order that any liquid or condensate can drain out Take care to clean and dry rotors that will be stored for weeks or months before use Cover them with a fine layer of silicone grease using a spray Equally rotors stored in a cold room must be protected against humidity by a layer of silicone grease 7 4 Action to be taken in the case of broken glass or accidental spillage Before any intervention switch off and unplug the centrifuge The user is responsible for the decontamination in case of spilling contaminated liquid in the centrifuge 7 4 1 Material presenting no toxic biological or radioactive risk Wear protective gloves to avoid any risk of injury and a mask in case of airborne contaminants Dismount the rotor Remove all debris and mop up spillages using compresses or absorbent
