A centrifugal extractor is a commonly used solvent extraction device for separating and extracting compounds. In order to ensure the proper operation of the centrifugal extractor and extend its service life, regular maintenance is required. The following are the maintenance steps for the centrifugal extractor:
1.Clean the exterior surfaces: Clean the exterior surfaces of the centrifugal manifold with a mild detergent and a soft cloth to ensure that dust and dirt are reduced. Be careful not to use acidic or alkaline cleaners to avoid damaging the device.
2.Clean the centrifuge chamber: Clean the centrifuge chamber regularly to prevent the accumulation of sample residues. First, the centrifuge tube and rotor inside the centrifuge chamber are removed. Then, use a mild detergent and a soft brush to clean the residue inside the centrifuge chamber. Then rinse with clean water and dry with a clean, soft cloth.
3.Check the centrifuge chamber seals: Regularly check the condition of the centrifuge chamber seals. If the seal is found to show signs of damage or aging, it should be replaced in time. Ensure that the seal is intact to prevent sample leakage in the centrifuge chamber.
4.Check the centrifuge rotor: Check the condition of the centrifuge rotor regularly. If the rotor is found to show signs of damage or deformation, it should be replaced in time. Ensure the balance and stability of the rotor to ensure the proper operation of the centrifuge.
5.Lubricate the bearings: Regularly apply the appropriate amount of lubricating oil to the centrifuge bearings to reduce friction and wear. Be careful not to use too much lubricating oil to avoid contaminating the sample.
6.Calibrate the centrifuge: Calibrate the speed and time of the centrifuge at regular intervals. Use a professional calibration instrument and calibrate according to the requirements of the equipment manual. Ensure the accuracy of the speed and time of the centrifuge to ensure the reliability of the experimental results.
7.Regular maintenance: Regular maintenance of the centrifugal extractor, including cleaning the filter, checking the connection of the power cord and plug, checking the working status of the motor and controller, etc. If any faults or abnormalities are found, the parts should be repaired or replaced in time.
8.Safe use: When using a centrifugal extractor, pay attention to safe operation. Follow the operating procedures of the equipment manual, avoid overloading operation, and ensure the stability and safety of the centrifuge.
Focus on centrifugal extractor for many years, rich experience in the industry, sophisticated technology, Seiko production, quality assurance!
In summary, centrifugal extractor maintenance includes cleaning external surfaces and chambers, checking seals and rotors, lubricating bearings, calibrating speed and time, regular maintenance, and safe use. Through regular maintenance, the normal operation of the centrifugal extractor can be ensured and its service life can be extended.
