Before using the centrifugal extractor, the following preparations need to be made first:
1.Ensure that the working environment of the centrifugal extractor is clean and dry, avoiding the impact of any impurities on the operation.
2.Clean the accessories of the centrifugal extractor, including centrifuge tubes, rotors, etc., to ensure that they are clean and odorless.
3.Calibrate the speed of the centrifuge to ensure accurate separation.
Precautions when operating.
When using the centrifugal manifold, follow these precautions:
1.Preparation of samples.
When preparing samples, the following points should be noted:
Samples need to be homogeneously mixed to ensure accurate separation.
Depending on the characteristics and needs of the sample, select the appropriate centrifuge tube and rotor.
Ensure that the volume of the sample meets the capacity requirements of the centrifuge and avoid overloading or undercapacity.
2.Centrifugation parameter setting.
When setting centrifuge parameters, the following points should be noted:
According to the nature of the sample and the separation requirements, select the appropriate rotation speed and centrifugation time.
Avoid excessive centrifugation speeds and long centrifugation times, which may damage the sample or affect the separation.
During operation, the operating status of the centrifuge is checked regularly to ensure the accuracy and stability of the parameters.
3.Safe operation.
The centrifugal extractor is a delicate piece of equipment, and in order to ensure safety, the following should be noted:
Before the operation, personal protective equipment should be worn, including laboratory gloves, goggles, etc.
It is strictly forbidden to open the lid of the centrifuge or interfere with the running state during operation.
Avoid placing the centrifuge in an unstable or vibrating environment to prevent damage to the machine or accidental injury.
4.Maintenance & Cleaning.
In order to maintain the stability and longevity of the centrifugal extractor, pay attention to the following maintenance and cleaning matters:
Clean the tubes and rotor regularly to avoid the accumulation of impurities that can affect the separation.
Calibrate the speed and temperature of the centrifuge to ensure its accuracy.
Regularly check the wear and tear of centrifuge parts and seals, and replace or repair them in time.
Troubleshooting & FAQs.
During the use of a centrifugal extractor, there are some glitches and problems that may be encountered, the common ones include:
The centrifuge does not start: check if the power supply is on, check if the power cord is damaged.
Abnormal sound or vibration during centrifuge operation: stop the machine to check whether the centrifuge base is stable and whether there are any debris or foreign objects entering.
Unsatisfactory separation: Check that the sample has been prepared correctly and that the parameter settings are accurate.
When encountering the above problems, you should stop the operation in time and seek help from professional maintenance personnel.
By following the above operation precautions, the normal operation of the centrifugal extractor can be ensured, the accuracy and stability of the separation effect can be improved, and the smooth progress of the experiment can be ensured.
