Overview
The Fuzhou fully automatic water quality detection distillation instrument ammonia nitrogen distiller is a new intelligent distillation treatment device that integrates constant temperature heating, automatic control of distillation endpoint, and cooling water circulation according to the laboratory distillation pretreatment operating procedures. This instrument is widely used in various chemical laboratories that require distillation treatment, such as environmental protection, aquaculture, water supply and drainage, universities, research institutes, factories, and mining enterprises. It is suitable for distillation treatment of volatile phenols, ammonia nitrogen, and moisture in Kjeldahl nitrogen oil; Distillation operations for residual sulfur dioxide, formaldehyde, alcohol content, etc. in the field of food testing.
Product Details
Fuzhou fully automatic water quality detection distiller ammonia nitrogen distiller
1. The distillation device is cumbersome to connect, occupies a large space, lacks experimental safety guarantees, and has high labor intensity;
2. Traditional distillation devices use open flames or high-power electric furnaces for direct heating, which consumes a lot of power and causes uneven heating, leading to explosive boiling;
During the distillation process, the temperature of the heating source is uncontrollable, which can easily cause the bottle to explode, resulting in short circuits, electrical leakage, and poor safety;
4. The cooling water source is tap water, which cannot be recycled and wastes water resources;
5. The distillation endpoint needs to be manually controlled without anti backflow protection, which often leads to distillation failure.
1Fully automatic distilleroperation steps
1. Plug in the power, check the distillation instrument to ensure that each heating hole can be heated normally, turn on the circulating water switch, and check if there is any water leakage at each interface to ensure the normal operation of the instrument.
2. Take 250ml of the sample into a 500ml all glass distillation flask, add 50ml of distilled water, and add a few drops of methyl orange indicator. If the sample does not appear orange red, phosphoric acid solution needs to be added.
3. Start heating and distillation. When the distillate reaches 250ml, stop heating and dilute to 250ml with distilled water.
4. Open our company's extractor and check if the instrument is working properly. After the inspection is complete, transfer all 250ml of distillate to the 500ml separating funnel that comes with our extractor.
5. Add 2.0ml of buffer solution into the separating funnel, set the extraction intensity to 40Hz, time to 90s, and residence time to 0, extract once, and mix the solution evenly.
6. Add 1.5ml of 4-aminoantipyrine solution, maintain the same extraction intensity, time, and frequency, extract once, and mix the solution well.
7. Add 1.5ml of iron, maintain the same extraction intensity, time, and frequency, and extract once to mix the reagent with the water sample. Let it stand for 10 minutes.
8. Add 10ml to the above-mentioned separating funnel, set the extraction intensity to 35Hz, time to 60s, residence time to 30s, and extraction frequency to 3 times. After setting, press the start button to start extraction. After extraction, let it stand and separate into layers.
9. Wipe the inner wall of the neck tube of the separating funnel with dry defatted cotton or filter paper, insert a small ball of dry defatted cotton or filter paper into the neck tube, pass the layer through the dry defatted cotton ball or filter paper, discard a few drops of the initial filtered extraction solution, and directly place the remaining into a colorimetric dish with an optical path of 20mm.
10. Measure the absorbance at a wavelength of 460nm as a reference. 11. Blank experiment: Distilled water is used as a substitute for the sample, and its absorbance is measured according to steps 4-10. Simultaneously measure the blank and sample.
IIFully automatic distillerPrecautions
1. The buffer solution is prepared with ammonia water, so the extraction intensity should not be too high when mixing. It is necessary to ensure sufficient and uniform mixing at an appropriate intensity, otherwise it will cause a larger blank.
2. When releasing liquid, it should form droplets, not lines.
1. Model: JTZL-6
2. Heating method: using imported far-infrared ceramic heating furnace, infrared radiation heating (no open flame heating, waterproof);
3. Cooling method: Built in closed loop reflux system, automatic cooling, no need for external cooling water source;
4. Heating units: 4-6, can be individually controlled for a single hole;
5. Heating time: 5-8 minutes;
6. Distillation speed: 12ml/min;
7. Time control: adjustable from 0-200 minutes;
8. Distillation endpoint control: automatic detection of distillation endpoint function, dual control of weighing and time, automatic stop of heating;
9. Single furnace heating power: 0-800W (single hole adjustable);
10. Heating power: 2400W-4800W (adjustable);
11. Anti reverse suction: equipped with anti vacuum solenoid valve, with anti reverse suction function;
12. Distillation flask specifications: 500ml X6250 X6 or 500ml X4250 X4. More specifications are available;
13. Rated voltage/frequency: 220V/50HZ;
14. Rated power: 2400W adjustable;
Fuzhou fully automatic water quality detection distiller ammonia nitrogen distiller
Jinan Tongxin Tianbo Technology Development Co., Ltd. is a distributor of instruments and equipment. In early September 2021, we found Jutong Electronic Integrated Distillation Instrument. The end user is a testing company that often tests water samples and water quality. There are no excessive requirements for the equipment, so the salesperson recommended the simple integrated distillation instrument JTZL-6C This product, which uses far-infrared ceramic heating instead of high-power electric heating, is more energy-efficient and environmentally friendly. Each of the six integrated operations can be controlled separately, with a timing function. It is equipped with a six position distillation bottle, condenser tube, and recovery bottle, without the need for additional consumables. It can be used for conventional water quality ammonia nitrogen and volatile phenol distillation. If the temperature requirements are high, external circulating water can also be connected, which is very suitable for customers' requirements. The price is also very reasonable and cost-effective. Finally, the procurement contract was signed at the end of September.
Precautions for Intelligent Integrated Distillation Instrument
When using the instrument for the first time, it is recommended to use pure water or distilled water to prevent the formation of scale after long-term use. The liquid level should be raised to the red mark on the liquid level window, and it can be reused for more than six months. If the liquid level is below the yellow line and the cooling effect is poor, do not add water again beyond the red marked line.
2. The connection between the distillation flask and the condenser flask is well sealed, and the top sealing plug of the distillation flask is effectively connected to the solenoid valve through a hose to prevent air leakage.
During the experiment, it is forbidden to place other debris near the tray to avoid affecting the accuracy of weighing.
When the temperature in summer exceeds 25 ℃, the cooling effect will decrease. It is recommended to install an external cooling device or connect tap water for cooling.
When the room temperature is below 0 ℃ in winter, it is necessary to do a good job of keeping the instrument warm to prevent the condensation device from breaking and becoming unusable.
6. The weighing sensor has a range of 3kg. If there are other requirements, please use the time control mode.
7. For two consecutive distillation experiments, to ensure condensation effect, do not turn off the switch for cold water circulation after the initial experiment is completed.
