The constant temperature oscillation incubator, as a core laboratory equipment, is widely used in microbial cultivation, cell experiments, and biochemical reaction research. It provides a stable environment for the sample through precise temperature control and oscillation functions, but the stable operation of the equipment depends on standardized operation and regular maintenance. The following will be discussed from three aspects: usage, daily maintenance, and troubleshooting, to help you efficiently manage equipment.

1、 Standardized use: Ensure experimental accuracy

Preparation before startup

Environmental requirements: The equipment needs to be placed on a well ventilated workbench away from direct sunlight, with the back and wall kept at a safe distance30cmThe above spacing is to facilitate heat dissipation. It is recommended to control the ambient temperature within10-30℃, humidity≤85%.

Power check: use220V±10%The50HzPower supply and ensure good grounding. The power carrying capacity of the socket needs to be≥1kWAvoid sharing with other high-power devices.

Sample placement: Place the culture bottles symmetrically on the tray, with consistent liquid volume to avoid oscillation and imbalance. Triangle bottles or test tubes should be securely fixed to prevent tipping over.

Parameter setting and operation

Temperature control:

press“SET”Press the key to enter the temperature setting mode, and use the“▲/▼”Key adjustment target temperature (range)0.1-60.0℃）Step by step0.1-0.5℃.

Set temperature control coefficient（1-8The higher the value, the stronger the heating power when approaching the set temperature, which can avoid temperature overshoot.

The recommended protection value for the compressor is set to3Exceeding the gear limit can extend the lifespan of the equipment.

Oscillatory parameters:

After turning on the oscillation switch, set the speed through the speedometer（60-260rpm）Long press to quickly adjust.

Timed function support0-240Minute short run or“ON”Normally open mode, automatically maintains a constant speed and timer after startup.

Operation monitoring: After startup, observe the temperature stability and oscillation uniformity, and check the internal status through the lighting. Avoid frequent door opening to prevent temperature fluctuations.

Shutdown process

After the experiment is completed, press“STOP”Press the key to stop oscillation, and turn off the power after removing the sample.

When not in use for a long time, unplug the power cord, clean the interior, and drain the water from the humidification tray (winter antifreeze).

2、 Daily maintenance: Extend equipment lifespan

Cleaning and disinfection

Shell cleaning: Regularly wipe the outer surface with a mild cleaning agent and avoid using corrosive solvents.

Internal cleaning: After the experiment, remove any residue and wipe the inner wall with a soft cloth dipped in clean water. Do not rinse or soak directly.

Filter maintenance: Clean the air inlet filter every month to prevent dust from blocking and affecting the smooth airflow.

UV disinfection: Optional UV sterilization system can be used to regularly disinfect the interior of the box and kill floating bacteria.

Performance calibration and inspection

Temperature calibration: Use a standard thermometer to check the displayed temperature every quarter, and the deviation exceeds±1℃Adjust the controller accordingly.

Vibration inspection: Ensure the platform is stable without any abnormal noise, tighten the screws, and prevent uneven vibration.

Electrical safety: Every year, professional personnel inspect the wear and grounding status of wires and plugs.

Lubrication and component replacement

Transmission part: Fill the bearings every six months1Number Calcium-Sodium based grease, filling amount occupies bearing space1/3.

Vulnerable parts: After one year of use, check the motor and compressor for noise, replace the belt in a timely manner if it is worn or the electronic control components fail.

3、 Fault handling and safety tips

Common troubleshooting

Abnormal temperature: Long press“SET”key10Restore default settings in seconds and recalibrate temperature.

Unstable oscillation: Check the balance of the tray, tighten the screws or replace the belt.

Compressor noise: Avoid continuous start-up, ensure good heat dissipation, and contact maintenance if necessary.

Safety operation standards

It is strictly prohibited to insert fingers into the gaps between moving parts to prevent injury.

Heating objects should be cooled to room temperature before being placed in the box to avoid damage to the refrigeration system.

Be sure to unplug the power supply when cleaning the equipment to prevent electric shock.

Conclusion

The stable operation of the constant temperature oscillation incubator depends on“standardized usage+regular maintenance”Double protection. By scientifically setting parameters, strictly cleaning and disinfecting, and promptly handling faults, the repeatability of experiments can be significantly improved and the lifespan of equipment can be extended. It is recommended that the laboratory develop a maintenance schedule to record each inspection and repair, providing data support for equipment management.
