Biochemical incubators are widely used in laboratories for various applications such as water body analysis, BOD determination, bacterial cultivation, mold and microorganism preservation, and plant breeding. Proper usage and maintenance of these devices are essential to ensure accurate results and prolong their lifespan. Below is a detailed guide on how to use and maintain a biochemical incubator.
**How to Use a Biochemical Incubator**
1. **Loading the Sample**
Open the incubator door and place the items you wish to process on the inner shelves. Ensure that the objects are evenly distributed to allow proper air circulation. Once everything is in place, close the door securely.
2. **Power Connection**
Connect the incubator to a power source by inserting the three-pin plug into an appropriate socket. Turn on the power switch located on the control panel. A digital display will appear, indicating that the device is operational.
3. **Setting the Temperature**
Use the temperature controller on the panel to set the desired internal temperature. If the set temperature is 5°C or more above the ambient temperature, make sure to set the cooling transfer switch to “RT + 5°C.†For more detailed instructions, refer to the user manual provided with the device.
4. **Starting the Process**
Once the settings are confirmed, the incubator will begin to regulate the temperature. It may take some time for the internal temperature to reach the set value. After the required processing time has elapsed, the operation is complete.
5. **Shutting Down**
After the process is finished, turn off the power supply. Wait until the internal temperature approaches the ambient temperature before opening the door. Carefully remove the processed items from the incubator.
**Important Precautions When Using a Biochemical Incubator**
1. **Avoid Flammable Substances**
Never place flammable or volatile chemicals inside the incubator, as this can pose serious safety risks.
2. **Handle Malfunctions with Caution**
If any unusual signs such as strange odors, smoke, or malfunctions occur during operation, immediately turn off the power and contact a professional technician. Do not attempt to repair the device yourself.
3. **Keep the Equipment Clean**
Regularly clean the interior walls and the outer surface of the incubator. Avoid using acidic or alkaline cleaning agents, as they may damage the equipment. Keeping the glass clear helps in monitoring the process effectively.
4. **Proper Storage When Not in Use**
If the incubator is not in use for an extended period, follow these steps:
- Drain the water from the bottom tray.
- Set the temperature to 42°C and run the unit for 5 hours.
- Open the door every two hours to release moisture.
- After the process, unplug the device and store it in a dry place.
5. **Regular Maintenance**
If the incubator remains unused for a long time, always unplug the power cord. To prevent electrical damage, it is recommended to operate the device for 2–3 days at regular intervals (such as once per quarter) to keep the internal components dry and functional.
By following these guidelines, users can maximize the performance and longevity of their biochemical incubator while ensuring safe and efficient operation. Whether for research, testing, or sample preservation, the correct use of this essential laboratory equipment is key to achieving accurate and reliable results.
