    Principle of laboratory ultrapure water equipment:

    It is usually composed of three parts: raw water pretreatment system, reverse osmosis purification system, and ultra-purification post-treatment system. The purpose of pretreatment is mainly to make the raw water reach the reverse osmosis membrane.

    Separation of the inlet water requirements of the components to ensure the stable operation of the reverse osmosis purification system. Reverse osmosis membrane systems are the most cost-effective purification method for removing more than 98% of ions, organics, and (theoretically) 100% of microorganisms from raw water in one go. The ultra-purification post-treatment system further removes the remaining trace ions, organic matter and other impurities in the reverse osmosis pure water through a variety of integrated technologies to meet the final water quality index requirements of different uses.

    Standard configuration of laboratory ultrapure water equipment:

    1.Integrated PPF precision filter element: filter sediment and particulate matter;

    2.Integrated activated carbon filter: adsorption of organic matter and residual chlorine.

    3.Reverse osmosis membrane device: the first step is desalination and removal of bacteria and organic matter from tap water;

    4.Pressure Pure Water Bucket: Stores reverse osmosis pure water and provides water intake power at the same time;

    5.Ion exchange column: the second step of desalination, the resistance is more than 10 megaohms;

    6.Nuclear-grade ultra-purification column: the third step is deep desalination, with resistance of more than megaohms;

    7.Terminal 1 micron microfiltration: filters fine particulate matter;

    8.Micron pore size terminal filter for ultrapure water (optional): remove bacteria and impurities;

    There are many brands of laboratory ultrapure water machines on the market, and there will be no unified pricing, so there will be no more accurate answers to this kind of questions, and I can only say that there is an approximate domestic high-end brand equipment** in 4-160,000 + (Dohe DHT-Bio, German research and development), imported high-end brand equipment ** in about 7-250,000 + (Merck Millipore, Thermo Fisher Thermo), and low-end domestic brands can also be bought in 2-60,000, specific** It is still determined according to the needs of users, and let's take a look at the factors that affect the ultra-pure socks guessing water machine in the laboratory

    1. Water requirements: water consumption (in the case of homogeneity, the greater the water production), water quality requirements (pure water level, resistivity, TOC value, bacteria, heat source and other indicators), the more demanding the requirements, the greater the technical difficulty, and the higher the price of ultrapure water.

    2. Equipment functions: multi-channel water quality monitoring, TOC** monitoring, EDI module, resistivity monitoring, consumables life reminder, data traceability, connectivity, etc.; Generally, TOC** monitoring (optional) will be used in the first-class ultrapure water machine, and the addition of a TOC monitoring can be tens of thousands; The application of continuous electrodeionization EDI technology can greatly reduce the cost of consumables; In short, the more advanced the technology and the more functions, the higher the ** will naturally be.

    3. National standard European standard: short-term use customers with low requirements for water quality, simple equipment function requirements and limited budget will generally choose the national standard laboratory ultrapure water machine, as long as it meets the national standard, use it first, and then change the equipment when there is a higher demand later. However, universities, pharmaceutical industries, clinical and first-class laboratories will still prefer high-end products with excellent quality (the purification process is designed and manufactured in accordance with the requirements of European standards with relatively high requirements), requiring the preparation of ultrapure water with different water quality specifications, and to be able to continuously and stably provide reliable water quality; It has high requirements for equipment stability, low failure rate, and professional and efficient after-sales technical services to ensure the quality of experiments and the reliability of results.

    The price difference between the ultrapure water machine of the European standard laboratory and the national standard equipment is generally 2-80,000 yuan, which should be determined according to the technical requirements of the equipment.

    The above three points are important factors affecting the laboratory ultrapure water machine, of course, there are other factors, such as different equipment accessories, different manufacturers, etc. In fact, what users are entangled with is not the specific ** of the laboratory ultrapure water machine, but which price to choose, the procurement personnel can choose a few more manufacturers with strong production strength and excellent research and development technology, strictly control the quality, and set a suitable budget, in order to choose a high-performance tanji price ratio equipment.

    How to choose an ultrapure water machine for laboratory, it is recommended that you consider and choose from the following three aspects:

    1. Analysis of self-water demand: including raw water quality analysis, effluent water quality analysis, self-water consumption analysis, equipment floor area, installation site confirmation, pipeline layout, etc., on the basis of careful analysis of the above points, we can correctly select the appropriate pure water equipment.

    2. Analysis of the strength of the manufacturer: the current water treatment manufacturers are particularly many, many businesses are not practical, and need to consider before choosing: the actual plant area of the manufacturer, the number of companies, the technical team, the brand influence, the installation case, various qualification certifications, etc., and the choice of powerful manufacturers can ensure product quality and after-sales service.

    3. Product analysis: the same water output, will also be differentiated because of different manufacturers, first of all, we need to understand where the differentiation is, the selection of pure water equipment needs to pay attention to the core components of the product, and there is no need to choose cheap to poor manufacturers to affect the use of shoddy products.

    Ultrapure water is used in almost every lab, whether it is for high-performance liquid chromatography and mass spectrometry, as well as protein purification and DNA extraction. Laboratory ultrapure water system is a commonly used ultrapure water preparation system in the laboratory, and there are many domestic and foreign water purifier manufacturers, such as: Millipore, Pall, etc., and the domestic Lefeng Rephile

    Wait a minute. So how to chooseHow to choose a laboratory ultrapure water system? It is believed that the following aspects need to be considered when choosing the right water purification equipment:

    1. Water quality should be stable.

    Due to the influence of region, climate and other factors, the quality of tap water is very unstable, which requires the water system to be able to produce pure water that meets specifications consistently, regardless of the influence of incoming water. Therefore, the reverse osmosis device must be a secondary reverse osmosis, which cannot be achieved by the primary or secondary reverse osmosis of an ordinary water system.

    2.Save on consumables.

    Frequent replacement of consumables keeps water systems costly. If a water system with more purified resin is selected in the purification column, the increased exchange capacity will greatly increase the amount of treated water, and the cost of use will be relatively reduced. Ultrapure water consumables generally need to be replaced once in 2-3 years, if you want to reduce the later investment cost estimate, it is relatively cost-effective to choose a domestic pure water meter.

    3. Real-time data transmission system.

    In order to ensure that the water machine can always run smoothly and stabilize the water production, it is necessary to monitor and transmit real-time data to the water machine system.

    To sum up, if the ultrapure water system selected by the laboratory can monitor and record the operation status of the water machine, the use of consumables, the date of delivery, the batch, the quality of the effluent, etc., the user can clearly know the quality of the produced water, the frequency of replacement of pure water consumables, which parts of the pure water meter need to be repaired and replaced, etc.
