Credit Awarded: Upon successful completion of the examination for this subcourse, you will be awarded 5 credit hours. To receive credit hours, you must be officially enrolled and complete an examination furnished by the Nonresident Instruction Branch at Fort Sam Houston, Texas. A listing of correspondence courses and subcourses available through the Nonresident Instruction Section is found in Chapter 4 of DA Pamphlet 350-59, Army Correspondence Course Program Catalog. TEXT ASSIGNMENT Paragraphs 1-1 through 1-10. LESSON OBJECTIVES After completing this lesson, you should be able to: SUGGESTION MD0368 1-1. Identify operational procedures. 1-2. Identify the steps for performing preventive maintenance checks and services (PMCS). 1-3. Identify the calibration and verification procedures. After completing the assignment, complete the exercises at the end of this lesson. It is designed for use in clinical laboratories for frequently performed separations in hematology, chemistry, urinalysis, blood banking, micro-biology, and cytology. Additional applications for the centrifuge are in industrial and university laboratories for many general procedures in chemistry, pharmacology, food processing, and agriculture. Because of its compact size, the centrifuge will fit into most standard size refrigerators or can be placed in a cold room for low temperature centrifugations. 1-2. DESCRIPTION a. Safety Requirements. The Dynac II Centrifuge was designed to meet the electrical safety requirements of Underwriters' Laboratories (UL) and Canadian Safety Association (CSA). Other advanced safety features to protect the operator are also incorporated to fulfill the safety standards of OSHA. b. Guard Bowl. The centrifuge incorporates a one-piece aluminum guard bowl attached to a stable base assembly. The guard bowl, which is of heavy gauge construction, affords maximum protection to the operator. The finish is baked enamel inside and out to facilitate cleaning. c. Motor. The centrifuge motor is attached to a mounting plate which is shock-mounted to the base by means of three vibration isolators. Four rubber feet are bolted to the bottom of the base plate. The motor incorporates permanently lubricated bearings. Various shield configurations are available to accommodate tube sizes ranging from 1 milliliter (ml) to 100ml. This permits the centrifuge to be used for a variety of micro and semi-micro work. You can easily install and lock on rotors to the centrifuge shaft by means of a drive pin and thumb screw. MD0368 1-2 e. Front-Panel Controls. Front-panel controls include an illuminated power switch, run-brake switch, automatic timer, adjustable speed control, and tachometer. You can continuously adjust speed over the range of 500 revolutions per minute (rpm) (minimum) to a specific maximum, depending upon the rotor and shield configuration used. f. Additional Safety Features. Additional safety features on the centrifuge include a transparent, shatter-proof, polycarbonate cover equipped with a positive latch. A latch interlock system prevents you from operating the centrifuge while the cover is open. Once the cover is closed and latched and the centrifuge is operating, a zero speed control switch prevents you from opening (unlatching) the cover until the rotor slows to less than 1 revolution per second. An external fuse, located on the back of the machine, prevents damage to the centrifuge in the event of external power surges or internal shorts. 1-3. OPERATING CONTROLS Refer to figure 1-1 for an illustration of the location of the controls on the centrifuge. Figure 1-1. Operating controls. MD0368 1-3 a. Power Switch. The illuminated power switch on the left side of the console applies power to the centrifuge. In this position, with the power switch on and the timer set to the desired spinning time, the motor is actuated to begin the centrifuge cycle. When you manually hold down the switch in the BRAKE position, the switch actuates an electric brake which will bring the rotor to a gentle stop in less than 30 seconds. To actuate the brake, perform the following: (1) Press and hold the switch down. The brake will be activated as long as the switch is held down. (2) NOTE: Release the switch as soon as the rotor comes to a stop. For delicate sedimentations, release the switch just before the rotor comes to a stop and let the rotor coast gently to a stop. (3) DO NOT HOLD THE BRAKE SWITCH DOWN AFTER THE ROTOR HAS STOPPED. If you hold it down too long, the rotor will automatically begin accelerating in the opposite direction.

Maximum angular velocities and relative centrifugal Forces for Dynac II Centrifuge rotors (Model 0103 at 120 volts alternating current (vac), 60 hertz (Hz) and Model 0106 at 220vac, 50 Hz). (Concluded) d. Timer. Spinning time is controlled by a 30-minute timer with a hold position for continuous operation. Operating the timer automatically turns on the centrifuge, provided the power switch is on and the cover is securely latched. (1) To set the timer, turn the knob clockwise to the desired setting. The centrifuge will now operate to the end of the timed cycle and then shut off automatically. (2) For continuous operation, turn the knob clockwise, to the HOLD position. The centrifuge will now operate continuously until it is manually shut off. CAUTION: Never operate the centrifuge without a rotor installed. You could damage the tachometer. f. Cover Safety Latch Assembly. The centrifuge cover is held closed by a lever-type lid latch which is spring-actuated to release when pressed. In addition, the latch assembly on the centrifuge bowl incorporates the following safety features: (1) Safety switch. When the cover is closed and latched, an electrical interlock is engaged, and power is supplied to the motor. You cannot start the centrifuge while the cover is open. (2) Zero speed switch. Once the centrifuge is running, a zero speed switch prevents the cover from being opened (unlatched). You cannot open the cover until the rotor slows to less than 1 revolution per second (50rpm). (a) an audible click. To lock the cover, press down on the latch and cover until you hear (b) To open the cover, wait until the rotor has stopped spinning and then press the latch as shown in figure 1-3. Figure 1-3. Cover latch. MD0368 1-7 1-4. LOAD BALANCING For smooth centrifuge operation and extended equipment life, it is essential that you balance the loads as equally as possible. For best results, the use of a balance is recommended to obtain loads of equal weight. The angular distribution of material to be centrifuged is critical where loads are not of equal weight. If you cannot equalize the amount of fluid in the opposite tubes, fill the shield around the lighter tube with water until the loads are balanced. NOTE: 1-5. Never attempt to balance by adding weights, mercury, or shot to the bottom of a tube or shield. SPEEDS AND RELATIVE CENTRIFUGAL FORCES a. Maximum Velocities. Figure 1-2 lists the maximum angular velocities and relative centrifugal forces obtainable with each of fourteen interchangeable rotor and shield configurations. Tip radius for each configuration is also listed. The maximum velocities and centrifugal forces in figure 1-2 were derived by operating the Model 0103 Centrifuge at 120 vac, 60 Hz and Model 0106 Centrifuge at 220 vac, 50 Hz. Rcf is defined as the force acting on the sample being centrifuged relative to the force acting on the sample in the earth's gravitational field. The operator can calculate the correct tachometer speed (rpm in thousands) corresponding to the required rcf specified for a test, using the following formula: Rpm in thousands (tachometer speed) equals the square root of rcf divided by 28.4R. Where: Rcf equals the relative centrifugal force specified for the particular centrifugation procedure. R equals tip radius of shield (in inches) obtained from Figure 1-2 for the rotor centrifugation being used. Avoid spilling liquids into the centrifuge bowl. If the interior of the centrifuge contains dust, glass particles, or other foreign matter, it is possible for these contaminants to be stirred into the air and deposited into specimen tubes. Keep the centrifuge interior clean to prevent contamination of samples. 1-7. HAZARDS Basic safety precautions must be observed when operating the centrifuge in order to avoid the hazards of electrical shock or other physical injury. a. The Dynac II Centrifuge is not to be used in a Class I, Division 1, Group C hazardous location defined by the National Fire Protection Association, Bulletin No. 56A (Inhalation Anesthetics), as extending upward to a level of five feet above the floor where flammable anesthetics are used. b. To avoid electrical shock, follow these procedures: (1) Plug the power cord only into a grounded 3-wire receptacle. (2) Never remove the grounding prong from the power plug. (3) Always unplug the power cord before attempting to service the centrifuge. (4) Immediately have a worn or damaged power cord or plug replaced by an authorized serviceman. MD0368 1-9 c. To avoid physical injury, never attempt to override the cover switch and lock while the rotor is spinning. 1-8. PREVENTIVE MAINTENANCE CHECKS AND SERVICES NOTE: Motors in both Models of the Dynac II Centrifuge incorporate permanently lubricated bearings.
