The time for the rotary evaporator to enter our field of view is not long, but as the market is more and more widely used, its application fields are also very much. It has applications in schools, medical, scientific research, petrochemical, etc. It is easy to operate and safe to use. The appearance is exquisite, the water purity is high, and it is highly praised by all units. Because everyone has less contact, there will be some doubts about the use and installation. I will give you a brief explanation below.
Installation method of quartz automatic double distilled water:
1. Open the box, remove the cold tube, and insert one end of the sanding port into the bottom horizontal flask in sequence.
2. Connect the rubber tube with reference to the schematic. The top cover can be covered or not (preferably covered). The water nozzle is slanted from the upper left side and slowly placed on the instrument.
3. Connect the cold suspected pipe outlet pipe (the inner group) to the connected olefin barrel. (Note: the round hole will introduce rubber into the barrel)
Way of working:
4. Turn on the electric front water inlet valve to be introduced into the water inlet of a horizontal flask, and let it flow into the flask. The water level is half-filled until there is water in the overflow; the Other is led to the water tank. .
5. Plug in the power, turn on the electric switch No. 1, and the work indicator light is on, indicating that one flask starts to work, and a steamed water flows into the electric No. 2 flask to a certain water level.
One hour) Turn on the two cold suspect inlet valve, wait for the outlet to flow out and then turn on the power supply to start the distillation.
Quartz automatic double distilled water cleaning method:
The working time of the device is long, and scale is generated. The scale can be poured into the scale of the horizontal flask by using 20% ​​nitric acid. Soak for four hours and drain from the drain. Rinse with tap water, rinse three times and rinse with ionized water three times.
Maintenance and maintenance of quartz automatic double distilled water:
6. In case of water or power failure during daily work, please turn off the power at any time to avoid damage to the instrument and more likely to prolong its service life.
7. When working for a long time, the electric heating wire will be aging. It is necessary to check regularly whether it needs to be replaced. When the power is turned on every time, a bright spot is found to indicate that the wire is broken and replaced in time. Don't wait when you are completely disconnected.
8. To replace the electric heating wire, pull the heating wire to a certain length (depending on the length of the electric heating tube), and insert it through the electric heating tube until it is returned and then straighten the two ends to about 5CM, then insert the magnetic joint, and now tighten. Until it is not loose.
Before using and using quartz automatic double distilled water, you must pay attention to the correct operation and maintenance, and should pay attention to protect the instrument from impact. Because the distilled water is made of all-quartz glass, it is easy to break and develop. Regular maintenance of the equipment, so that the equipment can work better for us.
Phosphate fertilizer is a fertilizer with phosphorus as the main nutrient. The full name of phosphorus fertilizer. Rational application of phosphate fertilizer can increase crop yield, improve crop quality, accelerate grain crops to promote fullness of seeds, promote flowering results of cotton, melons, solanaceous vegetables and fruit trees, increase the rate of results, and increase sugar content of sugar beets, sugar cane, watermelon, etc. The oil content of rapeseed.
1. Minimize contact with the soil, and concentrate fertilization, such as strip application and acupoint application.
2, try to increase the chance of contact with the root system
3, reduce the fixation by soil iron and aluminum
Zinc fertilizer and phosphorus fertilizer
When zinc Zn Zn fertilizer and phosphate fertilizer are mixed together, zinc phosphate which is not easily dissolved in water is formed. The roots of crops are difficult to absorb and utilize. Therefore, when applying zinc sulfate, it is necessary to avoid contact with phosphate fertilizers such as superphosphate, heavy superphosphate, diammonium phosphate and potassium dihydrogen phosphate, and it is not possible to mix them together.
The application of zinc sulphate as a base fertilizer can be carried out by uniformly mixing zinc sulphate with farmyard manure, and then applying phosphate fertilizer when planting. It is also possible to uniformly apply the phosphate fertilizer to the farmyard manure as a base fertilizer, and then apply zinc sulfate when planting. This creates a barrier between the zinc fertilizer and the phosphate fertilizer to prevent them from coming into contact with each other.
