Shanghai Haozhuang Instrument Co., Ltd. has developed a Haozhuang (LNB) carbon dioxide incubator, which is energy-saving and environmentally friendly, leading the country.
The classification is divided into two types according to the heating method: gas jacket and water jacket:
Both gas-jacketed heating and water-jacketed heating are accurate and reliable, and they have their own advantages and disadvantages. Water jacket heating is to maintain a constant temperature by surrounding the inner box with an independent water jacket layer. Its advantages: water is a good thermal insulation substance. When a power failure occurs, the water jacket system can Maintaining the temperature accuracy and stability in the incubator for a long time is beneficial to users who are not stable in the experimental environment and need to maintain long-term stable culture conditions. Air-jacket heating directly heats the inner box through heaters located in the gas jacket layer of the box, also known as six-sided direct heating. Compared with the water jacket type, the air jacket type has the characteristics of faster heating and faster temperature recovery than the water jacket type incubator, which is particularly beneficial for short-term cultivation and cultivation that requires frequent opening and closing of the door. In addition, the air jacket design is more simple for the user than the water jacket.
Maintaining a constant temperature in the carbon dioxide incubator is an important factor for maintaining healthy growth of cells, so an accurate and reliable temperature control system is an indispensable important part of the incubator. In order to make the incubator work more stably, we recommend users to choose carbon dioxide incubators with independent triple temperature control function, that is, temperature control, over temperature alarm control and ambient temperature monitoring.
Precautions for use 1. Close the door of the incubator to avoid gas leakage and affect the test effect;
2. After the refrigeration system stops working, clean the working chamber and glass observation window with a soft cloth;
3. Before each shutdown, each control switch should be in a non-working state before cutting off the power;
4. The carbon dioxide incubator should be placed on a flat ground, the environment should be clean and tidy, dry and ventilated;
5. Do not adjust the pressure of the inflow gas to be too large, so as not to break the pipeline and damage the detector;
6. Before the instrument is used, all control switches should be in a non-working state, and the speed control knob should be placed in the minimum position;
7. Properly use and pay attention to the maintenance of the instrument so that it is in a good working state, which can extend the service life of the instrument;
8. It is not suitable for the cultivation of articles containing volatile chemical solvents, low-concentration explosive gas and low ignition point gas, and toxic substances.
9. Keep the air in the incubator clean and disinfect it regularly; always pay attention to the amount of distilled water in the distilled water tank in the box to maintain the relative humidity in the box and avoid the evaporation of the culture solution;
10. During the continuous working period of the instrument, periodic inspection should be done every three months; check whether there are water drops, dirt, etc. falling on the motor and exposed refrigeration components; clean the dust and dirt on the compressor, condenser; check Fuses, control elements and fastening screws.

In order to improve the clarity of the pattern and the photosensitive paste the uniform distribution of the screen surface, the drying process should ensure that no dust pollution around, and should be operating in the darkroom or yellow light. Place the screen frame, printed side up, keep the screen level. Dust free fan drying, but in order to speed up the drying speed drying box (Note: the maximum temperature must not exceed 40 ° C).
Scratch coating layer is fully dry, wet surface will affect the light sensitivity of the photosensitive paste must be done before the exposure. Not completely dry, there will be underexposed
Drying operation guide:
1) The third scratch coating method, each coated once must achieve sufficient
drying of a coating, otherwise, make moisture caught in the middle of the
photosensitive layer.
2) If possible, should be kept to a constant indoor temperature. If the indoor
humidity to extend the exposure time, especially in the summer, if not lower
humidity device, should pay special attention to this point. In fact, the cost
of installing lower humidity device is not too high
3) often used in the industrial drying machine (maximum temperature 40 °
C), especially in the more humid environment. Must know, however, that the
expansion due to heating causes the screen frame chromatic inconvenience that
is difficult to achieve chromatic accurate. Therefore, in order to ensure that
the chromatic accurate, all wire mesh and network box must be dried in the same
environment. And they should be allowed to return to room temperature before
making an exposure.
4) of the operating environment, should the exposure, dry place with the screen
frame making cleaning separately, because more humid in the production of wire
mesh and cleaning area
