RS-II High Purity Water Machine for Water Treatment Laboratory

Xinrui Laboratory High-Purity Water Analysis Instruments can almost completely remove conductive media from water, as well as reduce colloidal substances, gases, and organic matter to very low levels. The resistivity exceeds the limit value of 10–15 MΩ·cm. Ultrapure water is a standard that is difficult to achieve with ordinary pure water equipment. It typically involves four major steps: pretreatment, reverse osmosis technology, high-purity treatment, and post-treatment, utilizing multiple methods such as multi-stage filtration, high-performance ion exchange (polishing), ultrafiltration filters, UV lamps, and TOC removal devices.
Detailed Introduction
Xinrui Laboratory High-Purity Water Analysis Instruments are commonly used in scientific laboratories and can meet the technical requirements for purified water in experiments.
Xinrui High-Purity Water Analysis Instruments are designed with different pretreatment functions, configured with various filtration units tailored to different water qualities, such as softening and strong activated carbon adsorption units for high hardness and high turbidity.
Small microcomputer control function; operated by a small microcomputer, the machine automatically shuts down in cases of water shortage or full water, and performs an automatic rinsing function each time it starts.
Compared with traditional electric thermal water distillers, it offers higher purity and stability of output water; simple operation, no need for dedicated personnel; no electric heating tube, no scaling, and high safety.
Features of Xinrui Laboratory High-Purity Water Analysis Instrument System:
· Uses silent pumps, no vibration, noise, or electromagnetic radiation during operation, with no impact on the working environment.
· Employs reverse osmosis membranes with stable performance, high desalination rate, and long service life.
· Uses exchange resin to make (ultra) purification columns with high exchange capacity and high output water quality.
· Features an all-metal chassis with electrostatic spray painting, effectively preventing water vapor corrosion.
· Separated water and electrical circuits to avoid the impact of humid environments on the circuitry.

Why Use a High-Purity Water Machine
· Stable water output quality, simple testing method, no need for repeated experiments · Large water output, basic models at 10L/H or 20L/H, up to 100L/H · Output water at room temperature, no cooling required,可以直接试用, reducing experiment analysis time and avoiding secondary pollution during cooling · Produce water on demand, avoiding time wasted during transportation, speeding up analysis experiment efficiency · Most importantly, the instrument operates at only 25 watts, compared to electric thermal water distillers which typically consume 7–8 kW,常规10 kW, or even 15 kW, making it more energy-efficient and reducing daily operating costs · For more comparisons with traditional electric thermal water distillers, see the next section
