1, water requirements: water consumption (homogeneous, the larger the price of the larger the price of the water production), water quality requirements (pure water level, resistivity, TOC value, bacteria, heat and other indicators), the more demanding, the greater the technical difficulties The more demanding the requirements, the greater the technical difficulty, the higher the price of ultrapure water machine.
2, equipment features: multi-channel water quality monitoring, TOC online monitoring, EDI module, resistivity monitoring, consumables life reminder, data traceability, connectivity and other functions; generally in the first level of ultrapure water machine will be used in the TOC online monitoring (optional), increase a TOC monitoring, the price can vary by tens of thousands of dollars; continuous electrodeionization of the use of EDI technology can greatly reduce the cost of consumables; in short, the more advanced technology, the more technically difficult, the higher the price of ultrapure water machine. Cost; in short, the more advanced technology, the more features, the price is naturally higher.
3, the national standard/European standard: the water quality requirements are not high, simple functional requirements of the equipment, the budget is limited to the short-term use of the customer will generally choose the national standard laboratory ultrapure water machine, as long as it meets the national standard can be used first, and then change the equipment when there is a higher demand. But like universities, pharmaceutical industry, clinical and government laboratories, etc. will still prefer excellent quality of high-end products (purification process in accordance with the higher requirements of the European standard requirements for the design and production), the requirements of the preparation of ultrapure water of different water quality specifications, and to be able to continue to provide a reliable and stable quality of water; the stability of the equipment requires a high degree of stability, low failure rate, after-sales technical service professional and efficient, in order to ensure that the quality of the experiments and the reliability of the results. European standard laboratory ultrapure water machine and the price of national standard equipment will generally be a difference of 2-8 million, depending on the technical requirements of the equipment.
The above three points are important factors affecting the laboratory ultrapure water machine offer, of course, there are other factors, such as different equipment accessories, different manufacturers. In fact, the user is not entangled in the specific price of the laboratory ultrapure water machine, but in the end to choose which price, purchasing staff can choose more than a few manufacturers with strong production strength, excellent R & D technology, strict quality control, set a suitable budget, in order to select cost-effective equipment.
