Carbon dioxide incubator heating methods have advantages and disadvantages
Precautions for use 1. Before using the instrument, each control switch should be in non-working state, and the speed control knob should be placed in the minimum position; The purpose of washing hands is to remove stains and bacteria on the hands, so the washing force is the first thing to consider, but the washing force and degreasing force is proportional to the excellent decontamination with strong degreasing effect, should choose mild performance of non-stimulating surfactants.
First fully wet your hands with water, take appropriate amount of hand sanitizer in the palm of your hands fully rub at least 30 seconds, in this process should pay attention to the rub to the fingertips, fingers, and let the foam can cover all parts of the entire hand, after rubbing rinse with running water. Finally, be careful to use a clean dry towel or paper towel to dry, preferably not dry, because the rapid evaporation of surface water will cause the skin to lose water, resulting in dry skin, become rough.

2. After the refrigeration system stops working, wipe the working chamber and the glass observation window with a soft cloth;
3. Before each stop, each control switch should be in the non-working state to cut off the power;
4. The carbon dioxide incubator should be placed on a flat surface, and the environment should be clean and tidy, dry and ventilated;
5. Do not adjust the pressure of the inflowing gas to an excessive level to avoid breaking the pipeline and damaging the detector;
6. Close the door of the incubator to prevent gas leakage and affect the test results;
7. Proper use and attention to the maintenance of the instrument, so that it is in good working condition, can extend the life of the instrument;
8. Not applicable to the cultivation of articles containing volatile chemical solvents, low concentrations of explosive gases and low ignition gases, and toxic substances.
9. Keep the air in the incubator clean and disinfect regularly; always pay attention to the amount of distilled water in the distillation tank to keep the relative humidity inside the tank while avoiding evaporation of the culture solution;
10. During continuous operation, the instrument should be regularly inspected every three months; check whether there are water droplets, dirt, etc. falling into the motor and the exposed cooling element is compared.
Both air jacketed and water jacketed, both heating systems are accurate and reliable, and they all have their own advantages and disadvantages. The gas-sleeve heating is to directly heat the inner tank through the heaters in the gas jacket of the tank, and is also called direct heating on six sides. Compared with the water jacket type, the gas-sleeve type has the characteristics of quick heating and rapid recovery of the water-type incubator, which is particularly advantageous for short-term cultivation and the need for frequent switching of the door. Water jacket heating maintains a constant temperature by enclosing an internal tank through a separate water jacket. The advantage is that water is a good thermal insulation material. When a power failure occurs, the water jacket system can Keeping 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 stable culture conditions for a long time. In addition, the air-sleeve design is simpler for the user than the water jacket. Clean the compressor, dust and dirt on the condenser; check the fuses, control components and fastening screws. The constant temperature in the incubator is an important factor in maintaining healthy cell growth, so an accurate and reliable temperature control system is an indispensable part of the incubator. In order to make the incubator work more stably, we recommend that users choose a carbon dioxide incubator with independent triple temperature control functions, namely temperature control inside the box, over temperature alarm control and ambient temperature monitoring.
Abundant and durable foam and easy rinsing is an important index of the quality of hand sanitizer products. Abundant and durable foam and easy rinsing can bring users a relaxed experience of washing hands without burden. Therefore, foaming and foam stabilization properties and easy rinsing should be given priority in the formulation design.Can remove bacteria, is the key to hand washing can achieve true cleanliness, is mainly used as hand sanitizer in public places.
