6. e Place the buckets to the rotor 9 Connect the centrifuge to the power supply Figure 4 16 5 4 6 1 DRIVE SYSTEM The rotor is driven by a three phase asynchronous motor The microprocessor control system assures the correct drive speed The force applied to the rotor is directly related to the shape of the rotor the swing out rotor receives more load than the angle rotor does Longer radius and more accessories increase the load of the rotor and decrease the spinning speed The centrifuge does not allow the rotor to spin at a speed which it cannot resist mechanically Please make that sure the correct type of rotor is selected during programming SECTION 6 CLEANING AND PERIODIC MAINTENANCE PERIODIC MAINTENANCE Disconnect the power cable and after the maintenance check the presence of the mains grounding line Rotors should be washed after every use especially if a spillage has occurred in warm water containing a few drops of liquid soap A mild washing liquid is ideal as a cleaner Rotors and other accessories must be clean if any spillage or chemicals occur You may use a nylon brush to clean the buckets and tube inserts of the rotor Do not use metal brushes Dry the rotor with a piece of soft absorber cloth Please make sure that the buckets and inserts are well dried you may use hair dryer The buckets of the swing out rotors should be greased frequently with the oil provided with the centrifuge Please
7. manually make sure that the rotor already stopped spinning Upon opening the lid lift tt by hand and observe the rotor If the rotor is still spinning close the lid and wait approximately 10 minutes before repeating the operation This operation must be carried by someone who is informed of the danger and of the precautions which must be undertaken 14 SECTION 5 OPERATING PRINCIPLES 5 1 PREPARATION OF THE ROTOR TO RUN e Before installation check the rotor for corrosion and cleanliness Chemical corrosion mechanical corrosion may do severe damage to the rotor and the centrifuge Particles which are stuck inside the inserts cause the breakage of tubes and lead to major imbalance please check to make sure that no particles are left on the rotor e The central hole of the rotor and the motor shaft should also be clean and dry before all centrifugal operations and they must be kept in that vvay all the time 5 2 LOADING The most important condition of an efficient centrifugation is to balance the tubes properly Loading must be done by meeting the requisites of static and dynamic balance Static Balance This balance states that diametrically oppositely replaced vveights are almost the same application the liquid level in the tubes should be at the same height to balance the load Dynamic Balance This balance states that diametrically oppositely replaced center of the gravity of tubes are symmetrical with respect to
8. remove the light oil from the pins and put a small amount of fresh oil every time you grease This will ensure free swinging of the buckets Most of the imbalance problems are mostly raised by the users who do not clean and oil the pins Please do not leave the rotor on a metal surface particularly stainless steel as electrochemical reactions set off easily with the aluminum or magnesium in the rotor Make sure that no deposit remains at the bottom of the bucket because the pressure of a flask or tube from above during centrifugation will certainly increase the chance of corrosion STERILIZATION Apply alcohol for example 70 ethanol or isoprophanol for 10 minutes against bacteria and viruses The rotors and buckets may be autoclaved at 121 C and under 215 kPa pressure for 20 minutes but please do not forget to remove all accessories Do not use formaldehyde for the sterilization process Phenol is a corrosive substance and should never be used Glutaraldehyde is a toxic substance and increases the rate of fatty acid in the body CORROSION INFORMATION Nuve rotors which are made of aluminum are designed to spin at proper RCFs for many years When used properly their resistance to corrosion and their life soan increases and the imbalance problems decrease All accessories should be checked thoroughly and regularly as almost all laboratories already have the conditions which lead to corrosion easily 17 6 3 1 Chemical Corrosion T

12. The corrosive material is pushed against the aluminum alloy by the centrifugation g force during the centrifugation This situation causes the stress corrosion to occur more quickly than the chemical corrosion does Microscopic cracks occur under the force of the centrifugation Every centrifugation causes the aluminum rotor to be attacked by the chemical more and more and eventually micro cracks decrease the resistance of the rotor against the centrifugation force Fortunately no crash occurs just after the first micro cracks have appeared as the rotors are manufactured according to the high safety limits The corrosion of the small amount of corrosive materials does not result in severe cracks but weakens the mechanical resistance of the rotor in the course of time The rotor s places buckets buckets edges and the base of the rotor should be checked regularly If needed they must not be used until a specialist has checked them thoroughly 6 5 CLEANING e Disconnect the centrifuge before cleaning There is no need of daily cleaning unless a tube breakage occurs or any liquid spills 6 6 ELECTRICITY Centrifuged at high voltages are present behind the panels These panels are electrically disconnecting Do not open the centrifuge 18 SECTION 7 DISPOSAL MANAGEMENT CONCEPT The currently valid local regulations governing disposal must be observed t is in the responsibility of the user to arrange proper disposal of the i

16. his type of corrosion is caused by chemical reactions The electrolide liguid on the surface of the material is the main cause of the chemical reaction If that electrolide liguid is allowed to stay at the surface corrosion occurs First discoloration appears and then the metal pittens Aluminum easily reacts with the ionic solutions The other causes of corrosion are as follovvs Chemical vapors in the laboratory environment which dissolve in the water on the rotor in refrigerated centrifuges Corrosive liguids which overflow from overfilled and unsealed tubes the liguids which spread out during centrifugation Contaminated and non cleaned buckets tubes and bottles NOTE If the centrifuged samples are corrosive only rinsing with water is not sufficient The residuals dissolve in the water and humidity on the rotor and in the buckets NOTE Some particles may stick to the tubes buckets and adapters These particles crash and do harm to anodized surface during centrifugation and ease the occurrence of corrosion 6 4 Stress Corrosion This type of corrosion is caused by the force of the centrifugation of the corrosive chemical which is already in contact with the alloy As the aluminum alloy contacts with the corrosive chemical the stress corrosion starts This type of corrosion is even more dangerous than the chemical corrosion as the effects of this corrosion are microscopic and very difficult to observe in the course of time
