七.于两次连蒸馏实验，为保冷凝效，一次试毕，水环之启闭无闭
QYZL intelligent integrated distiller laboratory distillation preadministration case, set huanhuhuo, distillation pole homemade, cold water circulation in one of the new intellectual distillation disposal. The apparatus is used for precise temperature control, self - control suction, even fire, anti - riot boiling, intelligent final control, etc. Easy to use ａnd environmentally friendly. The yield of excess certified laboratory distillation is 95%.
The instrument can be extensive used in environmental protection, the CDC, aquatic animals, for drainage, colleges ａnd universities, research institutes, factories ａnd the reserve of chemical laboratory distillation, such as fly, ammonia nitrogen, kjeldahl Yin distillation of water in the oil, etc.
Use time also:
I. for the first use of the integrated distillation instrument, use water or distilled water to prevent the formation of scale in the long daily use. Add the liquid level to the red line in the liquid level window, which can be used for more than half a year. If the liquid level minus yellow line cold effect is poor, add, do not cross the zhu marking line.
2. The junction between the distillation bottle ａnd the condensing bottle is sealed well, ａnd the top sealing plug of the distillation bottle is blocked due to the hose ａnd electromagnetic leakage.
3. During the experiment, all sundries must be kept away from the boat to ensure the accuracy of weighing.
Four. When the summer room temperature is 25 true, cooling efficiency will decline, not to mention the cold water or tap water cooling.
Five. When the room temperature is true in winter. , the cold ａnd warm of the equipment should be prepared in case the condensation unit becomes suddenly unusable.
Weighing sensor zui large range three, if he has to use the time line.
In two consecutive distillation experiments, in order to maintain the condensation effect, one trial, the opening ａnd closing of the water ring
