How to properly use the constant temperature and humidity incubator and maintain

From the description, how to correctly use the constant temperature and humidity incubator and maintenance, the suggestions are as follows;

1. Under normal circumstances, the constant temperature and humidity incubator should be placed at room temperature, and the laboratory that does not have this condition must be equipped with an appropriate air conditioner.

2. Adhere to the professional management and maintenance of special personnel, and the qualified units should send special personnel to the supplier factory for training and learning from time to time to obtain more professional maintenance and repair experience and ability.

3. Clean the condenser every 3 months, in addition to ensuring its inlet water pressure and inlet temperature, it is also necessary to ensure the corresponding flow rate, and regularly clean and descale the inside of the condenser to obtain its continuous heat exchange performance.

4. Clean the evaporator regularly: Due to the different cleanliness levels of the samples, a lot of dust and other small particles will be condensed on the evaporator under the action of forced air circulation, so it should be cleaned regularly.

5. The cleaning and balance of the circulating fan blade and condenser fan is similar to that of the cleaning evaporator, due to the different working environment of the test chamber, a lot of dust and other small particles will be condensed on the circulating fan blade and condenser fan, which should be cleaned regularly.

6. Cleaning of waterway and humidifier: If the waterway is not smooth and the humidifier is scaled, it is easy to cause the humidifier to dry burn, which may damage the humidifier, so the waterway and humidifier must be cleaned regularly.

7. Insist on setting the temperature near the ambient temperature after each test, cut off the power supply after working for about 30 minutes, and wipe the wall of the studio clean.

8. When the product is not in use for a long time, the product should be energized regularly every half month, and the power-on time should not be less than 1 hour.

A. Animal cell culture needs to use CO2 incubator, but plant cell culture does not need to use CO2 incubator, A is wrong; b. Liquid medium is required for animal cell culture, while solid medium is required for plant tissue culture, B is wrong; c. Animal and plant cell culture should be carried out under strict aseptic conditions, C is correct; d. Plant cell culture can reflect the totipotency of cells, while the principle of animal cell culture is cell proliferation, which cannot reflect totipotency

The maximum temperature of the incubator is 20 degrees.

The automatic thermostat type temperature control device is mostly used in the "metal sheet type". That is, a kind of metal sheet with a large coefficient of thermal expansion is used to make a spiral. One end of the metal sheet is fixed to the wall of the chamber, and the other end is equipped with movable contacts.

The two contacts are closed at room temperature. After the power is turned on, the temperature in the box rises, the metal sheet fixed here expands by heat, and the bending changes, so that the contact at the other end leaves, cuts off the circuit, stops heating, and the temperature of the ante blade drops. down to a certain level.

The spiral metal sheet is restored to its original state, and the two contacts are in contact again, and the circuit is connected and heated, so that the circuit is turned on and off to keep the constant temperature in the box.

Principle:

1. The water jacket type heats the liquid layer wrapped around the periphery through the stuffy ridge, and then heats the inside, which is slower, but can maintain a constant internal temperature for a long time and maintain the stable culture of the sample.

2. The electric heating film type directly heats the box through the electric heating film attached to the inner wall, and the heating is relatively rapid, and the interior can reach the required temperature in a short time.

3. Most of the computer intelligent control types use the microcomputer PID controller as the control unit, the thermal element as the thermometer, and the digital display of the set value and the measured value, so as to constitute a complete control system.

In the case of a constant temperature incubator, it is usually up to 60 degrees Celsius.

Constant temperature Fu Jingzhi culture manuscript buried box is generally the most lacking high temperature is 60 Suzhou Haisiyuan.

Incubator.

Hello dear and very happy to serve you <>

Let you wait for a long time, the reasons and solutions are as follows: 1. Check whether the constant temperature and humidity incubator identification plate is in the state of inactivation or operation, check the use record of the incubator, if it is normal, then hang the operation identification to the incubator, and you can operate. 2. Fill the water tank at the back of the main incubator with water.

3. Turn on the power switch on the control panel of the incubator, and the indicator light on the switch is on, and the temperature control instrument and humidity control instrument of the incubator are displayed: The "PV" line of the temperature control instrument (red) shows the measured value of the dry-bulb temperature, that is, the actual temperature in the incubator, and the "SV" line (green) shows the test temperature set value; The "PV" line (red) of the humidity control instrument shows the wet-bulb temperature measurement, which is the actual temperature inside the incubator, and the "SV" line (green) shows the wet-bulb temperature setpoint. 4. Temperature and humidity setting

Press the function key on the temperature control instrument first, at this time, the temperature value of the "SV" line will flash, and then modify the temperature set value by pressing the "" button of the temperature control instrument to make the temperature value of the "SV" line reach the temperature value required for the test, and then press "SET" to confirm. When the temperature is set, according to the relative humidity of a dry bulb temperature required for the test, check the difference corresponding to the data in the "relative humidity checklist", and then subtract the difference from the dry bulb temperature, that is, to obtain the set value of the humidity control instrument, and press the function key on the humidity instrument, at this time, the temperature value of the "SV" line will flash, and then modify the temperature set value by pressing the "" key of the temperature control instrument, so that the temperature value of the "SV" line reaches the temperature value required by the test, and then press "SET" to confirm. 5. Turn on the heating switch of the incubator, turn on the heating, the blower motor in the incubator will run, and the temperature control instrument will start to control the heater to work.

6. When the measured value of dry-bulb temperature reaches or approaches the set value of dry-bulb temperature, turn on the humidification switch, and the humidity control instrument begins to control the humidifier to work. 7. Turn on the refrigerator: After the temperature and humidity setting is completed, you can decide whether to turn on the refrigerator according to the test temperature, humidity and ambient temperature and humidity.

The general principle is that the test temperature is higher than the ambient temperature of 10 or more, and the test relative humidity is higher than the ambient humidity, the refrigerator can not be turned on. If the test temperature is lower than the ambient temperature, the refrigerator is turned on when the test relative humidity is lower than the ambient humidity. 8. After the test temperature is fully stabilized, if the temperature display value of the incubator does not reach the required temperature setting value, the temperature setting value can be slightly increased, and the temperature setting value can be slightly lowered.

9. According to the actual needs, whether to observe the sample, decide whether to turn on the lighting, and do not turn on the lighting under normal circumstances. 10. The incubator has its own temperature limiting device, when the test temperature reaches about 60, the heating power supply will be automatically cut off, and the over-temperature indicator will be on at this time. 11. After the constant temperature and humidity incubator is used, the use record should be filled in.

Use the how-to.

Operators need to read the instructions carefully to understand and be familiar with the functions of the incubator before turning on the power.

Turn on the power and press the power switch, and the power indicator will be on.

Set the temperature controller to the user's desired set temperature (this value should be 50C above room temperature).

When the incubator shows that the temperature reaches the set temperature, the heating is interrupted, the heating indicator is off, and the temperature can remain stable after 90 minutes of power-on at the standard ambient temperature, such as the real-time temperature in the incubator exceeds the set upper limit alarm temperature (factory set to 5), the thermostat temperature tracking alarm indicator lights up, and the heater power supply is automatically cut off at the same time.

For example, when the glass door is opened to take samples, the heater and circulating fan will stop working, and when the glass door is closed, the heater and fan can operate normally, so as to avoid the pollution of the culture and the overshoot of temperature.

Precautions and maintenance repairs.

The instrument should not be used under the conditions of high voltage, high current and strong magnetic field, so as to avoid interfering with the temperature controller and the risk of electric shock.

Electroplating parts and surface paint, should be kept clean frequently, if not used for a long time, should be coated with neutral grease or petroleum jelly on the electroplating parts to prevent corrosion, the incubator outside the plastic film dust cover to put the incubator in the drying room, so as not to damage the thermostat by moisture.

This product has been strictly debugged before leaving the factory, and the thermostat menu setting data should not be modified at will.

The shell of the culture sail hail shouting box must be effectively grounded to ensure the safety of use.

Do not place flammable and explosive materials for limb heating to prevent danger.

Do not place items with high acid and alkali to prevent the box from rotting.
