Desktop milk fat centrifuge is an important equipment used in laboratories to separate milk fat components, and its operating procedures directly affect the accuracy of experimental results and personnel safety. This article systematically outlines operational precautions to help you avoid risks and improve efficiency.
When operating a desktop milk fat centrifuge, the following key points should be noted to ensure safety, obtain accurate results, and extend equipment life:
•Preparation before operation: Wear personal protective equipment such as laboratory clothes, gloves, and goggles, check if the equipment power is well grounded (use a three hole socket and ensure grounding), and avoid the risk of electric shock. At the same time, check for any damage to the centrifuge and rotor to ensure that the workbench is flat, stable, and dry.
•Sample processing and balancing: Before use, the centrifuge tube and its contents should be precisely balanced, and the weight difference should not exceed the range specified in the instructions to prevent equipment vibration or damage caused by centrifugal imbalance. Avoid overloading during sample loading and ensure that containers such as milk fat meters are clean and leak free.
•Parameter setting and operation: Set the correct speed, time, and temperature according to the sample requirements (such as the milk fat centrifuge usually needs to be kept at a constant temperature of 50 ℃ -60 ℃), and check the maximum allowable speed and usage time limit of the rotor. Overloading is strictly prohibited. After starting, the instrument operation status should be observed throughout the process. If there is any abnormal sound or vibration, the machine should be stopped immediately for inspection.
•Safety operation regulations: Do not open the upper cover casually during equipment operation to avoid injury caused by high-speed rotating parts. If there is a sample leakage (such as spilled milk fat), it should be cleaned immediately to prevent corrosion of the components. At the same time, avoid debris entering the centrifuge chamber to prevent damage to the host.
•Cleaning and maintenance: Clean the centrifuge chamber, rotor, and accessories in a timely manner after use, wipe off moisture, and store them properly; Regularly inspect the rotor for corrosion or cracks, and replace it if necessary. For devices that have not been used for a long time, the internal cavity should be cleaned and run for several minutes to maintain dryness before being used again.
•Common problem handling: if the separation effect is poor (such as the lotion is notcompletelySeparation can be achieved by increasing the rotational speed or extending the centrifugation time appropriately; If the equipment makes abnormal noises or vibrates, it is necessary to stop the machine and check the rotor balance. When the temperature is too high, the device will automatically shut down for protection, and you need to wait for the temperature to return to normal before restarting.
Following these precautions helps ensure operational safety and equipment stability. If there are specific model differences, it is recommended to refer to the instruction manual of that model for adjustment.
