The benchtop low-speed centrifuge is a modern separation technique that has evolved from understanding how particles behave under centrifugal force. This technology has continuously improved over time, moving from basic low-speed medical centrifuges to high-speed models, ultracentrifuges, and now advanced refrigerated and large-capacity versions. These improvements have enhanced efficiency, precision, and the ability to handle larger sample volumes.
To use a benchtop low-speed centrifuge, you first place the sample into the provided centrifuge tubes. Make sure each tube contains an equal amount of material to maintain balance. Insert the tubes into the rotor holes, close the lid securely, and turn on the power. The machine will then enter its operational mode. You can set the desired centrifugation time using the timer function or manually adjust the speed, which typically ranges between 500 to 4000 revolutions per minute (RPM), depending on your needs.
During centrifugation, particles with different densities, sizes, or shapes settle at varying rates, allowing for effective separation. This makes the benchtop low-speed centrifuge ideal for biochemical research and handling large quantities of samples in laboratories.
Regular maintenance is essential for the proper functioning of the device. First, check the main power indicator light. If it's on, inspect the carbon brushes for wear. Replace them if they’ve worn down by more than one-third. If the power indicator is off, check the fuses and power connections. Ensure the power line is properly connected and replace any blown fuses.
Also, monitor the vacuum pump and oil pressure indicators. If the oil pressure is too high and the machine won’t start, check for blockages in the oil circuit, especially the throttle hole. Clean it if necessary. If the bearings are damaged or not rotating smoothly, clean or replace them. Low oil levels or excessive dirt can increase friction and prevent the motor from reaching full speed.
Check the commutator for oxidation or uneven surfaces. If the brushes aren’t making good contact, clean both the commutator and brushes to improve performance. If the rotor coil is shorted or open, use a multimeter to test it and consider rewinding if needed.
Always ensure the rotor is in good condition. Rotor damage can occur due to broken tubes, sample leakage, metal fatigue, or improper use. Avoid overloading or running the rotor at speeds beyond its rated capacity.
After use, clean the centrifuge chamber and rotor thoroughly. Remove any condensation and allow the chamber to return to room temperature before opening the door. Before starting a run, always balance the samples to prevent damage to the machine. After centrifugation, disinfect and sterilize the equipment as required.
If the rotor requires pre-cooling, follow the manufacturer’s guidelines. Proper storage and protection of the rotor, including the counting ring at the bottom, are also important for long-term performance. Regular maintenance ensures the centrifuge operates safely and efficiently over time.
