Capacity 400 ml Microprocessor control system Electronic 10 memory programs available Imbalance and cut off power system Motor at over heat protective device Safety Device Triple balance system Automatic Lid lock, lift cover and power cut off Fuse 6A Timer 1 ~ 99 min. digital time setting Weight (kg) 17 Dimension (cm) 6 x 4 x 9 Brake System Automatically brake system Power 110 / 0V, 50 / 60Hz Power Consumption 150W Basic Accessory Operation and maintenance manual 1

3 (Ⅱ) ROTOR AND ACCESSORY 1. Centrifugal force calculation: Use its speed and radius to calculate force as following formula. RCF=(rpm) x x R R: radius (cm) RCF: Relative Centrifugal Force ( x g ). Sterilizing and cleaning rotor: Rotor is made of stainless steel or steel or aluminum with high density coating and highly resistant to corrosion, but not fit to alkaline and strong acid substance. Don t heat the rotor to a high temperature (100 ) to clean or sterilize it.. Rotor Specifications: Rotor Type Capacity Max. speed Max.

5 1. When you take out centrifuge from carton, please check if there is any scratch, press trace and damage on knob or not. If yes, please contact local dealer immediately.. Please install the centrifuge on a horizontal and stable table or bench. If not, it will affect anti-vibration efficiency.. Please use power voltage as following range, to avoid electric shock please make sure to connect ground wire to the ground terminal. Power voltage 100V / 110V 0V / 40V Acceptable voltage range 90V ~ 110V / 99V ~ 11V 198V ~ 4V / 16V ~ 64V 4. Keep it away from dusty and moist working place. 5. Avoid the same power source with the large electric consumption machine at same time. 6. After dismantle or clean rotor, please must screw it tightly. (Ⅳ) OPERATION 1. Setting of Carrier (1) Carrier is composed of turning ring and bucket. Four carriers should be same type and put onto rotor at one time. Different type of carriers or to use separate bucket and carrier are prohibited. () Adapter is available for tube s diameter much smaller than carrier s, it can prevent tube broken from rotation.. Caution: a. Adapter should be placed into carrier properly, if it is slanted, then tube is difficult to take out from carrier. If glass tube is broken or if rotor elapsed over one year, then rotor needs to be renewed. Damaged rotor or rotor containing broken glass will cause glass tube broken easily. b. Carrier should be placed onto rotor properly, if not, it will be imbalance and destroy centrifuge, meanwhile to check if carriers swing normally by hand first. c. Stainless steel tube carrier can be used for acidity and alkalinity tube 4

separate tube and place such tubes into carrier for dummy purpose.

6 samples. (please purchase separately) Swing rotor Angle rotor Adapter 50cc 15cc 15cc 6cc Stainless steel adapter. Proper Setting of Tube & Sample (1) Tubes and sample in use must be arranged in even number. Glass tube must be placed in carrier, which are positioned symmetrically toward rotor center. If tubes are in odd number, then put same volume of water in a separate tube and place such tubes into carrier for dummy purpose. () Tube strength should consider if it could bear speed and centrifugal force or not. If not, the tube will be easy broken. () Please note tube length, if it is too long then the top of tube will hit the rotor and break. 5

THIS IS FOR SHORT TIME ROTATION OPERATION. LID OPEN : NOTICE THE LID OPEN ONLY WITH ROTOR STOP ABSOLUTELY, THEN THIS FUNCTION WORK. THE LID CAN NOT BE OPEN WHEN ROTOR STILL ROTATION. 4 RECALL PROGRAM : RECALL THE SEATED SPEED AND RCF ALSO TIME.. PUSH RECALL KEY, FIGURAL AFTER P FLASH, PUSH THE PROG KEY TO SELECTE THE PROGRAM THEN PUSH RECALL KEY. 5 MEMORY PROGRAMS : SET THE SPEED (RPM), (RCF) AND TIMER INTO THE MEMORY : WAY OF OPERATION: SET THE SPEED AND TIMER AND PUCH THE STORE KEY., YOU MAY SEE THE FLASH GO AFTER THE P PUSH THE PROG KEY, TO SLECT THE PRE SET NO. ( 0~9).THEN PUSH THE STORE, THE PROGRAM MEMORY DONE. 6 SELECT THE PRE SET NO : YOU MAY CHOOSE FROM 0~9, USE TOGETHER WITH 4 5 OPERATION. 7 LCD DISPLYA : SHOW SPEED(RPM), RCF TIMER, AND THE PRE SET PROGRAM NO. 8 SPEED SEATING : PUSH RPM, PUSH TO SEAT THE SPEED YOU NEED.
