What is a Water-Jacket Incubator?

Water-Jacket Incubator is high-precision constant temperature equipment, often used in medicine, agriculture, forestry, environmental science, scientific research, and education departments for plant tissue, germination, cultivation of seedlings, and cultivation of microorganisms.

The Water-Jacket incubator has a liquid crystal microcomputer controller with fixed performance. Suppose the incubator's temperature exceeds the set value, or the water level of the water jacket is too high or too low.

In that case, the sound and light alarm will be automatically returned, and the Heating will be stopped simultaneously as the water level is low.

The outer shell of the Water-Jacket incubator is usually made of asbestos plate or iron sheet spray paint. The inner layer is a water storage interlayer made of red copper skin, which is heated by heating the water with an electric heating tube. , Use air convection to make the temperature in the box uniform.

On the front side of the Water-Jacket incubator, there are indicator lights and a temperature adjustment knob.

When the power supply of the water jacket incubator is turned on, the red indicator light will be on first. Turn the knob to the desired scale according to the desired temperature.

When the temperature of the Water-Jacket incubator reaches, the red indicator light goes out, indicating that the inside of the Water-Jacket incubator has reached the required temperature, after which the temperature controller can automatically control the temperature in the incubator.

Prerequisites for using a Water-Jacket incubator

1. Use conditions of Water-Jacket incubator: Ambient temperature: 10-30℃; no intense light, no solid corrosive gas, good ventilation, relative humidity below 85%; power supply: ~200V±10%, 50HZ. A power socket with a capacity of not less than 1KW and a ground wire;

2. How to use the Water-Jacket incubator: Turn on the power supply: insert the three-pin plug into the power socket, and set the power switch on the panel to the "on" position. At this time, the instrument displays a digital display, indicating that the equipment is working.

Set the setting-measurement switch to set, adjust the temperature adjustment knob or touch key, and observe the indication that the digital thermometer is the desired set temperature value.

Put the setting-measuring switch to measure, and the equipment will enter the working state of automatic temperature control.

The three indicators of Heating, cooling, and protection alternately indicate the working state of the equipment.

Light switch. Set it to "on" when lighting is required. When the mold incubator is sterilized, turn on the germicidal light switch.

Instructions for use are required for intelligent and unique requirements.


What are the components of a Water-Jacket constant temperature incubator?

The shape of the Water-Jacket constant temperature incubator is vertical.

The box body and the outer door are made of a high-quality steel plate, and the surface is sprayed with plastic. The box door adopts a tempered glass observation window, which can clearly and directly observe the box's cultured items—the board's height.

Magnetic door seals on the outer door and the cabinet to ensure the tightness of the studio.

The studio adopts a "U"-shaped water tank for water isolation. There is a water inlet on the upper left side of the box, a water outlet on the lower left side, and an overflow rubber tube on the left back.

The back of the studio is equipped with a low-noise small fan to ensure temperature uniformity in the box.

It was filled with ultra-fine glass wool for insulation between the box shell and the studio.

The temperature control system consists of a sensor (Pt100 platinum resistance), a temperature controller, a heater, etc. When the temperature controller receives the sensor output resistance signal (100Ω at 0°C, 0.3Ω/°C), it is measured in the PV screen display studio. The actual temperature, when the input signal is less than the set value, the power tube (two-way thyristor) is turned on so that the heater can obtain enough electric power to generate heat.

On the contrary, the power tube without an electric power output heater does not heat.

The temperature controller has the functions of PID adjustment output characteristics, adjustable electric power output, error correction of the measured temperature, timing control, and change, and safety functions such as over-temperature or high and low water levels with lights and automatic cut-off output alarms.

How to install and debug the Water-Jacket incubator?

1. After the Water-Jacket incubator is placed on the ground, it should be placed smoothly. If the soil is uneven, it should be corrected.

2. The Water-Jacket incubator should be kept from the source of electromagnetic interference, and the grounding wire of the equipment should be effectively grounded.

3. Do not place the power cord close to the back, and do not let instruments or other objects press on the power cord so as not to damage the power cord.

4. The power supply is AC 220V 50HZ, a three-core socket above 16A must be used, and there is a reliable ground wire, and a two-core socket shall not be used without authorization.

5. Please do not use the Water-Jacket incubator in places with direct sunlight or high temperature and humidity.

6. When the Water-Jacket incubator is in regular operation, the placement of the contents in the box should not affect the air circulation to ensure the uniform temperature in the box.

7. Before using the Water-Jacket incubator, half of the water must be added to the inner compartment. Then the water level must be added to the appropriate position when the power is turned on.


How to use a Water-Jacket incubator?

I believe many people know the Water-Jacket incubator, and the Water-Jacket incubator is also widely used, but how to use the Water-Jacket incubator?

1. When the experimental items are put into the incubator, close the incubator door.

2. Before Heating with electricity, you must add water until there is water at the overflow port. To prevent the water from overflowing after Heating, release one liter of water in the box and then heat it with electricity, and use the same method to check regularly every month. Water level.

3. The sensor probe should be prevented from contacting complex objects and bumping the sensor probe during use to avoid damage.

4. Before use, you must pay attention to whether the power supply voltage used is consistent with the specified voltage and effectively grounds the grounding electrode of the power socket according to the regulations. Turn on the power, press the power switch, then the power indicator light will be on.

5. Adjust the temperature control setting to the desired temperature value.

6. When the measured temperature of the incubator reaches the set temperature, the Heating is interrupted, and the heating indicator light goes out. After 90 minutes of power on at the standard ambient temperature, the temperature can be kept stable. If the temperature in the incubator exceeds the set upper and lower limit alarm temperature, The temperature tracking alarm indicator light of the temperature controller is on, and the heater power is automatically cut off simultaneously.

What are the advantages of a Water-Jacket incubator?

The Water-Jacket incubator is used by factories and mines, colleges and universities, biology, agriculture, scientific research, and other departments as the necessary equipment for storing bacteria and biological culture. It is suitable for biology, chemistry, medicine, agricultural science, pharmacy, food, hygiene, and the environment. Conservation and other college scientific research units carry out experiments such as cultivation, breeding, and fermentation of various bacteria.

1. The water jacket type incubator has a digital microcomputer controller with a timing function. If the temperature in the box exceeds the set value or the water in the water jacket is too much or too little, it will automatically issue a light alarm and stop Heating.

Second, the water jacket heating method, double door structure, and motor control switch. When the inner glass door is opened, the breeze circulation and Heating will automatically stop without overshoot.

Three, stainless steel studio. The water jacket heating method has good temperature uniformity and can maintain a constant temperature for a long time after the power is cut off.

4. Independent temperature limit alarm system. If the temperature exceeds the limit, it will be automatically interrupted.

Is a Water-Jacket incubator or an electric heating incubator better for bacterial culture?

We are all very familiar with constant temperature incubators. Bacterial culture, breeding, fermentation, and continuous temperature experiments are all inseparable from regular temperature incubators.

Our common ones are electric heating incubators, Water-Jacket incubators, biochemical incubators, mold incubators, light incubators, carbon dioxide incubators, and so on.

Each has its characteristics and uses and introduces its differences and respective parts.

The first is the electric heating constant temperature incubator, which uses electric Heating.

The outer shell of the electric heating constant temperature incubator is made of cold-rolled plate electrostatic spraying, the inner tank is made of stainless steel, and the insulation layer is made of asbestos as the insulation material. Relatively poor, the temperature shock is rather extensive.

The second is the Water-Jacket incubator.

From the appearance, it seems that it is no different from the ordinary electric heating constant temperature incubator. However, the Water-Jacket incubator has a water inlet and an overflow port on the side of the box, which is used for adding water. The material of the outer shell and inner liner is the same as that of an ordinary constant temperature incubator. Still, the inner liner is a Water-Jacket incubator with a water storage interlayer made of copper leather. The heating tube heats the water in the interlayer and uses the convection of the water to form Heating on all sides can effectively ensure the uniformity of Heating.

Now, I believe that everyone has a new understanding of the Water-Jacket constant temperature incubator and the electric heating regular temperature incubator.

The electric heating constant temperature incubator is widely used because of its simple structure and relatively low price. The Water-Jacket incubator is undoubtedly a better choice for experiments with high-temperature or high heating uniformity requirements.
