Biochemical incubators are widely used in laboratories for various applications such as water body analysis, BOD determination, microbial cultivation, and preservation. They provide a controlled environment for experiments involving bacteria, mold, and other microorganisms. If you're new to using a biochemical incubator, it's important to understand the proper usage and safety precautions to ensure accurate results and maintain the equipment's longevity.
**How to Use a Biochemical Incubator**
1. **Place the Sample Inside**: Open the incubator door and place the items you wish to incubate on the internal shelves. Close the door securely.
2. **Connect the Power Supply**: Plug the three-pin power cord into an electrical outlet and turn the power switch on the control panel to the "ON" position. The digital display should light up, indicating that the device is operational.
3. **Set the Desired Temperature**: Use the temperature controller on the panel to set the required internal temperature. If the set temperature is 5°C or more above the ambient temperature, switch the cooling mode to "RT + 5°C". For detailed instructions on the temperature controller, refer to the user manual.
4. **Start the Process**: Once the incubator reaches the set temperature, the process will begin. Allow the samples to remain inside for the required duration.
5. **Turn Off and Retrieve**: After the processing time is complete, turn off the power supply. Wait until the internal temperature stabilizes near the ambient temperature before opening the door and removing the samples.
**Important Safety and Maintenance Tips**
1. **Avoid Flammable Substances**: Do not place flammable or volatile chemicals inside the incubator, as they may pose a fire hazard.
2. **Handle Malfunctions Carefully**: If you notice any unusual smells, smoke, or malfunctions during use, immediately turn off the power and contact a professional technician for assistance. Do not attempt repairs yourself.
3. **Keep the Equipment Clean**: Regularly wipe the inner walls and outer surfaces of the incubator with a soft cloth. Avoid using acidic or alkaline cleaners, as they can damage the surface.
4. **Moisture Control When Not in Use**: If the incubator is not being used for an extended period, drain the water from the base and fill the water tray. Set the temperature to 42°C and run the incubator for 5 hours, opening the door every two hours to release moisture. Afterward, unplug the unit and store it properly.
5. **Regular Operation for Long-Term Storage**: If the incubator will not be used for a long time, unplug the power cord. To prevent electrical damage, operate the device for 2–3 days every quarter to remove any accumulated moisture.
By following these guidelines, you can ensure safe and effective use of your biochemical incubator, helping to maintain its performance and extend its lifespan. Whether you're conducting routine experiments or specialized research, proper handling is essential for reliable results.
