The biosafety automatic de capping centrifuge is an experimental equipment specifically designed for processing biological samples (such as blood, cells, virus samples, etc.), aiming to ensure effective prevention of biological sample leakage during the centrifugation process and avoid operators from coming into contact with potential harmful substances. This type of equipment is commonly used in environments such as biological laboratories, hospitals, research institutes, etc. The following is the processing flow of the centrifuge:
1. Preparation stage
(1) Check the equipment
Check the appearance of the centrifuge: Ensure that there are no cracks or damage on the surface of the equipment, and all connecting components are intact.
Check the centrifuge cover and sealing system: Ensure that the centrifuge cover is properly locked and the sealing ring is intact.
Check the power supply and operation panel: Ensure that the power supply is functioning properly, the operation panel is clear, and the display is normal.
Check the automatic lid removal device: Ensure that the automatic lid removal function is normal and the operation is smooth.
(2) Sample preparation
Sample packaging: Packaging biological samples (such as blood, cell suspensions, etc.) into specialized centrifuge tubes. Ensure that the lid of the centrifuge tube is securely fastened.
Label and record: Clearly label each sample and record relevant information (such as sample number, processing method, etc.).
(3) Biosafety protection preparation
Wear protective equipment: Operators need to wear appropriate protective equipment, such as lab coats, gloves, face shields, or goggles.
Environmental safety inspection: Confirm that the centrifuge is in a biosafety cabinet or controlled environment, and ensure good ventilation in the laboratory.
2. Load the sample
(1) Centrifugal tube loading
According to the experimental requirements, place the sample container evenly in the centrifuge rotor. Ensure the weight symmetry of the sample to avoid equipment damage caused by imbalance.
Ensure sample lid is tightly closed: When loading centrifuge tubes, make sure the lid of the centrifuge tube is tightly closed to prevent liquid leakage during centrifugation.
(2) Installation of rotor and centrifuge tube
Choose the appropriate rotor and ensure that it is installed correctly. Different rotors are suitable for different types of centrifuge tubes (such as microcentrifuge tubes, 50ml centrifuge tubes, etc.), and attention should be paid to the symmetry and balance of the rotors during installation.
3. Set up the program
(1) Set centrifugal parameters
Set key parameters for centrifugation on the centrifuge operation panel, such as centrifugation rate (RPM), centrifugation time, temperature, etc. The setting parameters should be adjusted according to the sample type and experimental requirements.
Check program settings: Ensure that all settings parameters meet experimental requirements, including maximum centrifugal force (RCF) and time.
(2) Start the centrifuge
After confirming that the operation settings are correct, start the centrifuge.
During operation, the centrifuge should always be in a monitoring state to ensure smooth operation of the equipment.
4. Centrifugal process
(1) Automatic lid removal function
Biosafety centrifuges are usually equipped with automatic lid removal devices. After centrifugation, the equipment will automatically detach the lid of the centrifuge tube and provide a safety barrier to prevent sample leakage.
Automatic lid removal can reduce the risk of operators being exposed to potentially hazardous biological substances, especially when handling infectious substances.
(2) Observe the operating status
During the centrifugation process, it should be ensured that the equipment runs smoothly without any abnormal vibration or noise.
Pay attention to the temperature control system of the equipment to ensure that the temperature is controlled within the preset range and prevent the sample from being damaged by heat.
5. Ending and Sampling
(1) Automatic shutdown and cover removal
After the centrifugation process is completed, the equipment will automatically stop and the lid will automatically open (in biosafety devices, the lid usually only opens after it is completely stationary). At this point, the sample remains in a sealed state.
Observe for leaks: When opening the centrifuge cover, check for any leaks or damage to the sample container. If a leak is found, it should be immediately handled according to emergency procedures.
(2) Take out the sample
Carefully remove the centrifuge tube using specialized tools to avoid sample contamination or leakage. After removal, place the sample in a biosafety cabinet for further processing.
If there is a need for further analysis of the sample, it should be ensured that the container does not leak after removing the lid.
6. Cleaning and disinfection
(1) Centrifugal cleaning
Immediately clean the inside and outside of the centrifuge after each use. Use appropriate disinfectants to wipe the surface of the equipment, especially the parts that come into contact with biological samples, such as rotors and sealing rings.
Rotor cleaning: The rotor can be removed for cleaning as needed. Use a mild cleaning agent and ensure that the rotor is dry before returning it to the equipment.
(2) Sample container processing
Used centrifuge tubes should be handled according to laboratory safety regulations. For containers with biological hazards, use specialized waste disposal procedures for sterilization, destruction, or recycling.
7. Equipment maintenance and inspection
(1) Regular maintenance
Regularly inspect and maintain the centrifuge to ensure that the automatic lid removal function and protective system are in normal working condition. Regularly inspect components such as sealing rings, rotors, and monitoring systems.
(2) Safety record
After each use, an operation log should be recorded, detailing the usage parameters, operators, and maintenance status. This helps track device usage and troubleshoot issues.
8. Summary
The biosafety automatic de capping centrifuge effectively reduces the risk of operators being exposed to harmful biological substances during the processing of biological samples through an efficient automatic de capping mechanism and precise operating procedures. The safe use of this device requires strict adherence to operating procedures, including equipment preparation, sample processing, monitoring of centrifugation processes, and final cleaning and disinfection steps. Through reasonable operation procedures and maintenance management, the safe and efficient use of equipment can be ensured, and the biological safety of the laboratory environment can be guaranteed.
