Detailed instructions on the use of laboratory biochemical incubators

The biochemical incubator has a two-way temperature regulation system of refrigeration and heating, and the temperature can be controlled. It is a laboratory equipment indispensable for scientific research in plants, biology, microbes, genetics, viruses, medicine, environmental protection, etc., and is widely used in low temperature and constant temperature tests , Cultivation test, environmental test, etc. Its main features:

1. The heat insulation material of the box body is made of polyurethane foam foamed on site, which has strong anti-interference ability to external heat (cold) sources.

2. The inner cavity is made by engineering plastic molding process, which has strong corrosion resistance.

3. The all-glass door is convenient for observing the working cavity.

4. In order to protect the refrigeration compressor, the control circuit is designed with power-off protection and 4-minute delay function.

5. Automatic temperature control, using red LFD display to display numbers intuitively and clearly.

Instructions for use:

1. Place the incubator on a flat and solid ground, adjust the two supporting screws at the lower end of the box to make the box stable.

2. Plug in the power socket (the power supply should be well grounded), press the "power switch", the display is on, at this time the display shows the actual temperature inside the incubator and its working time.

3. Time setting: Time setting includes the setting of "minute" and "hour". Press the "SET" setting key, when the decimal point in the lower right corner of the "minute" nixie tube display is lit, that is, enter the "minute" setting state, and then press the "▲" or "▼" key to confirm the "incubator" work this time Minutes ”time (the longest is 59 minutes); press the“ SET ”key again, when the decimal point in the lower right corner of the“ hour ”nixie tube display is lit, it enters the“ hour ”setting state, then press“ ▲ ”or“ ▼ "Key to confirm the" hour "time (maximum 99 hours) of the incubator's current work.

4. Temperature setting: Press the "SET" key, when the decimal point in the lower right corner of the last digit of the temperature display lights up, it enters the temperature setting state, and then press the "▲" or "▼" key to confirm the incubator. Sub-set temperature (set temperature range is 5 ℃ ~ 50 ℃). When the above steps 3 and 4 are completed, press "ENTER" to confirm the working time of the incubator and the working temperature (set temperature) in the incubator. Note: After the temperature setting is confirmed, the temperature cannot be set back and forth at random, so as to avoid the compressor starting frequently, causing the compressor to overload, and affecting the service life of the compressor.

5. If you need to check the working time and temperature set by the incubator this time, press the "SET" key, the display panel will display the set time and temperature, and then press the "ENTER" key, the display value of the incubator returns To the original working state.

6. If lighting is needed in the incubator, press the "lighting switch"; if lighting is not needed in the box, the lighting switch on the panel should be placed in the "off" position to avoid affecting the upper temperature.

Matters needing attention and maintenance:

1. Be careful when handling, the angle between the box and the horizontal plane should not be less than 60 °.

2. When the use temperature is low, condensate will be generated in the incubator, and the water accumulated in the water tray at the bottom of the tank should be drained regularly.

3. In order to maintain the beauty of the equipment, it is not allowed to wipe the surface of the box with acid or alkali and other corrosive materials. The box can be wiped regularly with a dry cloth.

4. When the incubator is not in use, unplug it.

5. The minimum distance between the incubator and the wall should be greater than 10cm to ensure good cooling of the refrigeration system.

6. The room should be dry, well ventilated, the relative humidity should be kept below 85%, there should be no corrosive substances, avoid direct sunlight on the incubator.

7. The power supply used must have a reliable ground wire to ensure that the ground wire of the incubator is in reliable contact with the ground wire of the network power supply to prevent damage caused by electrical leakage or accidental network power supply.
