Scope of application of laboratory ultrapure water equipment

Laboratory ultrapure water equipment is used in a large number of pharmaceutical, electronics, chemical, biological, physical and chemical laboratories and other industries. Laboratory ultrapure water machine can usually produce pure water and ultrapure water two specifications of water. Mainly used for analytical tests with strict requirements, including the requirements of the particles of the test. Such as high-pressure liquid chromatography analysis of water. Primary water is commonly used in secondary water after quartz equipment distillation or reverse osmosis and ion exchange mixed bed treatment, and then filtered through a 0.2μm microporous membrane to produce. Secondary water, resistance requirements greater than 1MΩ (conductivity less than 1us/cm), mainly used for inorganic trace analysis and other tests, such as atomic absorption spectrometry analysis of water. Secondary water can be used for multiple distillation or reverse osmosis and ion exchange methods.

1: pretreatment system → reverse osmosis system → intermediate tank → coarse mixed bed → fine mixed bed → pure water tank → pure water pump → ultraviolet sterilizer → polished mixed bed → precision filters → water object (≥ 18MΩ.CM) (traditional process)

2: pre-treatment → reverse osmosis → intermediate tank → pump → EDI device → purified water tank → pure water pump → ultraviolet sterilizer → polished mixed bed → 0.2 or 0.2 MΩ. Polishing mixed bed → 0.2 or 0.5μm precision filter → water object (≥18MΩ.CM) (the latest process)

3.: Pre-treatment → first-stage reverse osmosis → dosing machine (PH adjustment) → intermediate water tank → second-stage reverse osmosis (positively charged reverse osmosis membranes) → purified water tank → pure water pump → EDI device → ultraviolet sterilizer → 0.2 or 0.5μm precision filter → water object ( ≥17MΩ.CM) (the latest process)

4: Pre-treatment → reverse osmosis → intermediate tank → water pump → EDI device → pure water tank → pure water pump → ultraviolet sterilizer → 0.2 or 0.5μm precision filter → water object (≥15MΩ.CM) (the latest process).

Ultra-pure water machine for laboratory

Ultra-pure water machine for laboratory is generally equipped with the following features:

1: With a complete purification unit to realize the use of tap water as the inlet, pure water and ultra-pure water as the outlet. Output of different standards of water to meet the water needs of various laboratories.

2: The new laboratory ultrapure water machine unit ultrapure water production is 40 times more than similar imported products, the cost of water is one-fiftieth of other products.

3: If the raw water quality is less than 2000μs, hardness ≦ 450ppm, this case can ensure that the quality of water production is stable at 5μs/cm or less, and the utilization rate of raw water up to 60% -80%

4: Users can also be purified water, ultrapure water, each rationing of water, as long as the amount of water set up to take, the ultrapure water machine will automatically produce the right amount of water, the amount of water from 10ml to 200 liters of free settings. 10 ml to 200 liters of water can be set freely, quantitative water withdrawal accurate to ± 2ml.
