LABDEX LX120LSC Low Speed Centrifuge

Safety Measures

Carefully read the manual before the installation or operating the instrument.

1. Before repairing, ensure the electricity is disconnected. Exercise caution if repairing requires electricity. Always cut off the electricity and wait 4 minutes before opening any cover.
2. Place the centrifuge on a steady floor or table and adjust the level for normal operation.
3. As safety measures, the centrifuge is equipped with a single-phase three-wire cable, and the longer cable connects with the casing as the protection grounding.
4. If your socket doesn’t have protection grounding, contact your electrician to replace the original socket without invalidating the security role of single-phase with a three-wire power cable.
5. When replacing parts, the technician must use parts from the manufacturer that serve the same function as the original. Using unrecognized alternative parts may lead to fire, electric shock, or other hazards.
6. The room should install an air conditioner to provide a good refrigerating effect when the temperature reaches more than 35℃.
7. To reduce the risk of electric shock, the centrifuge adopts the plug with three points which should connect with the socket with ground lead.
8. Make sure the wall socket is connected to the ground wire. The voltage of the power supply must by the voltage of the centrifuge.
9. Do not use the three-hole to two-hole power adapter the two-line expanding socket or the all-purpose power adapter without a ground wire.

Installation

Installation environment

1. The working environment temperature is 10℃ to 35℃, and the relative humidity is no more than ≤85%.
2. It is prohibited to put lab equipment with large heating production and strong vibration around the centrifuge.
3. Avoid direct sunlight and damp places.
4. Avoid Install in the place of corrosion, flammable, and explosive gases in the air.
5. Avoid installing in oil, dust, and metal dust places.

Installation place

1. The centrifuge should be installed on a flat and solid platform.
2. The distance between the centrifuge and the wall should be kept at 30cm at least for air circulation.

Installation steps

1. Open the outer package, carefully take out the centrifuge with the foam package, then put it on the even platform and take off the foam package. The four rubber feet of the centrifuge should touch the platform evenly.
2. Open the Lid: Poke into the Emergency lock hole by using the inner hexagon spanner which along with the centrifuge Tools, aims at the Inner six-angle Lock hole of the centrifuge, and open the lid in a clockwise direction. Then check the chamber of the centrifuge, take all the things from the chamber, and clean the Chamber.
3. Rotor install: Take the Rotor out of the package, and check whether the Rotor is ok and without any damage or deformation during the transport. Hold the Rotor by hand; put the Rotor on the Rotor shaft vertically and stably. Then one hand holds the Rotor Yoke, other hand screws the Rotor tightly by the spanner. You must make sure the Rotor is installed tightly before use.
4. The user must confirm the voltage of the power supply and the voltage of the centrifuge required are the same. Connect the power cord to the electric outlet on the centrifuge back first, and then put the plug on the other end into the external electric supply socket. Press one side marked “-” on the switch to power ON.

Adjust Centrifuge
Check whether the rotor is loose, the centrifuge is on the plat without any shack. If all is OK, then close the Lid and start the centrifuge directly (do not use the sample in the rotor). The mac speed setting is 1000r/min when run to 1000r/min then stops and set to 2000r/min stops then set to 3000r/min, 4000r/min, and 5000r/min until the max speed of the instrument is achieved if there is no abnormal phenomenon then the user can use it.

Operations

Control panel

Indicator light status and meaning

• Light OFF
• Light ON means choosing the program or displaying the process that will run, for example: If the Indicator Light becomes green flash, then it means that the centrifuge starts, and is in the state of speed. The light keeps green all the time means the centrifuge is running at the set speed. If the indicator light becomes a red flash, then it means that the centrifuge is stopped, and is in the state of speeding down. If the light keeps red all the time, then it means the centrifuge is stopped.

Operation steps

• Check the rotors and tubes carefully if cracked change them or it will damage the instrument.
• Install rotor: Take the Rotor out of the package, and check whether the Rotor is ok and without any damage or deformation during the transport. Hold the Rotor by hand; put the Rotor on the Rotor shaft vertically and stably. Then one hand holds the Rotor Yoke, other hand screws the Rotor tightly by the spanner. You must make sure the Rotor is installed tightly before use.
• Add Liquid in the tube and put the tube: When adding the sample in the centrifuge tube, it should use the balance to measure the same weight, then put into the tube symmetrically, in the rotor the weight of the symmetrical tube should be the same. The centrifugal tube should be put symmetrically, otherwise, there will be vibration, and noise because of the imbalance.
• Lid close: Put the Lid down, when the Lock hook touches the inductive switch, the Lid will automatically lock. When the display board displays the Lid in the close mode, and then it means that the centrifuge is closed.
• Set the parameter of the Rotor No, speed, time, Acc, Dec, and so on. Start and stop the centrifuge.
  • Start: Press the key to start the centrifuge, and then the Start Indicator Light will be light.
  • Automatically stop: When the time countdown to “0”, the centrifuge will slow down and stop automatically. When the speed is 0r/min, you can open the Lid Lock.
  • Manually stop: In the running status (the working time isn’t counted down to “0”), press the key, and the centrifuge will start to stop when the speed slows down to 0 r/min, you can open the lid
• Uninstall the rotor: When replacing the rotor, you should uninstall the used rotor, unscrewing the bolt with a screwdriver, and taking out the rotor after removing the spacer
• Shut off the Power: When the work is finished, then shut off the power and pull off the plug.

Maintenance

1. Wipe up the rotor with a neutral cleaning mixture after taking it out to avoid corrosion and then stock it in a dry and ventilated place.
2. The central hole in the rotor should be smeared with some lubricating oil for protection.
3. All action on the rotor should be soft, and the rotor should be taken out vertically to protect the shaft.
4. If the centrifugal chamber is unused wipe, it with water and some lubricating grease should be smeared on the drive shaft for protection.
5. Plug off the main power when the instrument has not been used for a long time

Troubleshooting

During operation, maybe there are following failures, refer to the following methods for easy troubleshooting.

1. Power ON but no display
   • Check whether the input power is by centrifuge-rated voltage by a multimeter. If it is a power problem, check and troubleshoot.
   • Check whether the power cord is connected to the main jack. If it is loosened and not connected properly, check and troubleshoot
2. Loud noise or abnormal vibration
   • Check whether symmetrically placed tubes are with same weight. If the weight does not meet the tolerance requirement, balance the weight gain and make sure symmetrically placed tubes with the same weight.
   • Check whether the tube is broken or not. If it is, clear the rotor and place it with the same weight tube.
   • Check whether the tubes are symmetrically placed in the rotor. If not, place them symmetrically.
   • Check whether the centrifuge is placed on a steady platform at the level and whether the stress on four feet is even or not.
   • Whether the rotor is bent or not. Whether the ground is stable and the strong shock around.
   • Check whether damping absorber parts are damaged or not. If it is, replace them.
3. Centrifuge not working
   • Check whether connecting terminals relate to the circuit board properly and whether the connection is loose or not. If it is fastened the connection wires properly
   • Check whether the input/output voltage is correct with the multimeter. If the power supply transformer is broken, replace it with the same model and specification transformer
   • Check whether the motor is energized with a multimeter. If the motor is energized but not rotated, it means the motor is damaged, and replace it.
   • If the motor can rotate but the rotor does not spin, check whether the rotor is installed correctly. If no abnormalities on the rotor.
