Biochemical incubator has the function of refrigeration and heating bidirectional temperature-regulating system and temperature controllable. It is an indispensable laboratory equipment for scientific research of plants, biology, microorganism, heredity, virus, medicine, environmental protection and other educational departments. It is widely used in low temperature and constant temperature test, culture test, environmental test and so on.
The main features
1. The insulation material of the box body adopts the foam plastic foamed by polyurethane, which has strong anti-interference ability to the external heat (cold) source.
2, the inner cavity is made by engineering plastic molding process, with strong corrosion resistance.
3. All-glass door is convenient to observe the working inner cavity.
4. In order to protect the refrigeration compressor, the control circuit is designed with the function of power off protection and 4-minute delay.
5, automatic temperature control, red LFD display digital intuitive and clear.
Directions for use
1. Place the incubator on a flat and solid ground and adjust the two supporting screws at the lower end of the cabinet to make the housing stable.
2. Plug in the socket (the power should be well grounded), press the "power switch", and the display screen will be on. The display screen shows the actual temperature and working time of the incubator room.
3. Time setting: time setting includes "minutes" and "hours". Press "SET" to enter the setting state of "minute" when the decimal point in the lower right corner of the display position of "minute" digital tube is bright. Then press "" or" "to confirm the" minute "time of the incubator work (the longest is 59 minutes). Press "SET" key again, when the decimal point in the lower right corner of the display position of "hour" digital tube is bright, that is to enter the setting state of "hour", and then press "" or" "key to confirm the" hour "time of the incubator work (the longest is 99 hours).
4, temperature setting: press "SET" button, when the temperature shows the last digit digital tube at the lower right corner of the decimal point, that is, enter the temperature setting state, and then press "" or" "button to confirm the incubator SET temperature (SET the temperature range of 5 ~ 50).
When the above steps 3 and 4 are completed, press "ENTER" to confirm the working time and working temperature in the incubator (set temperature). Note: when the temperature setting is confirmed, it is not allowed to set the temperature back and forth frequently, so as to avoid frequent startup of the compressor, which may cause overload of the compressor and affect the service life of the compressor.
5. If you need to check the working time and temperature SET by the incubator, press "SET" and the display panel will display the SET time and temperature. Then press "ENTER" and the display value of the incubator will return to the original working state.
6. If the incubator needs lighting, press the "lighting switch"; If the box does not need lighting, the lighting switch on the panel should be placed in the "off" position, so as not to affect the upper temperature.
Notes and maintenance
1. Care must be taken during handling. The Angle between the box body and the horizontal plane should not be less than 60°.
2. When the temperature is low, there will be condensed water in the incubator, and the water in the bottom of the tank should be poured out periodically.
3, in order to maintain the appearance of the equipment, do not use acid or alkali or other corrosive substances to wipe the surface of the box, the box can be wiped dry with dry cloth regularly.
4. Unplug the incubator when it is not in use.
5. The minimum distance from the incubator to the wall should be more than 10cm to ensure good heat dissipation of the refrigeration system.
6. The room should be dry and well-ventilated, with relative humidity below 85%, no corrosive substances, and avoid direct sunlight on the incubator.
7. The power supply must have a reliable ground wire to ensure that the ground wire of the cultivation box is in reliable contact with the ground wire of the network power supply to prevent the damage caused by leakage or accident of the network power supply.
Common failures of such instruments include: the compressor is not refrigerated, the temperature in the incubator is not even, or the circulation tuyere is frozen.
Under balanced mode, the compressor is always in working state with good refrigeration effect and can be effectively maintained.
If it is a single system of work when the temperature drops to a certain number of work, open or close the door will cause a large temperature fluctuations. Cause the compressor ordinary start easy to shorten its service life.
Uneven temperature: it is possible that the discharge items are too dense or the circulation fan in the box is not working for a long time. If the bulb is prone to heat for a long time, it will also cause uneven temperature. The air outlet will freeze. Use the heating element to melt the ice on the condenser. The melted water is likely to accumulate in the vents and freeze.
