When the blue hot and cold shock test box was tested, a special observation window was installed to observe the test. Many operators will perform experimental observations, so it is also a very important function. But once there is no progress in observing the experiment, why is it?
This is a problem caused by the malfunction of the blue-type cold and heat shock test box lighting. The inside of the box is without light. It can be observed because of the lighting. Therefore, the failure to observe can be attributed to the failure of the lamp. Under normal circumstances, there are two situations that cause the lamp to malfunction. The first is that the lamp is broken. To judge whether the lamp is good or bad, we can judge by looking at the filament of the lamp. The filament becomes black, then it is already broken. If it does not turn black, then there is no failure, which is good. Then you need to measure the lead-out line of the bulb between the extreme shells in a connected state. If it is not connected, it means that the lamp has been damaged or a part of the line is broken. The second is that the lamp is good, then it is very likely that the switch has been damaged, the switch is tested, if there is a problem, then only need to replace the good switch, or need to replace the rectifier.
From the above it can be seen that after the lighting lamp fails, its solution is not difficult at all, and it is relatively simple. It is very simple to solve this problem as long as you carefully check the tubes of the blue-and-cold thermal shock chamber.
The Histological microtome is widely used in hospitals, biomedicine, life science, agriculture and forestry, education, health and epidemic prevention, animal husbandry and veterinary, scientific research institutions, laboratories and other departments at all levels.
It is our latest model that integrates the advantages of precision, stability and simplification which manual microtome entails, also have the specimen retraction counted by stepping motor and spindle accurate. It is one of best model for histology and pathology preparation.
