High-Purity Water Treatment Instrument RS-II

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 of 10–18.3 MΩ*cm. Ultrapure water is difficult to achieve with ordinary pure water equipment. Typically, industrial high-purity water equipment employs four major steps: pretreatment, reverse osmosis technology, high-purity treatment, and post-treatment, along with multiple filtration methods, high-performance ion exchange (polishing), ultrafiltration filters, UV lamps, TOC removal devices, and more, to achieve a resistivity of 18.25 MΩ*cm.
Detailed Introduction
Xinrui Laboratory High-Purity Water Analysis Instruments are commonly used in scientific laboratories to 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 tank, and performs an automatic rinsing function each time it starts.
Compared to traditional electric thermal water distillers, it produces water with higher purity and stability; it is easy to operate and does not require dedicated personnel to monitor; it has no electric heating tubes, no scaling issues, and ensures good safety.
Features of the Xinrui Laboratory High-Purity Water Analysis Instrument System:
· Uses silent pumps, ensuring no vibration, noise, or electromagnetic radiation during operation, with no impact on the working environment.
· Employs reverse osmosis membranes, offering stable performance, high desalination rate, and long service life.
· Uses exchange resin for (ultra) purification columns, providing high exchange capacity and superior water quality.
· Features an all-metal chassis with electrostatic spray painting, effectively preventing rust caused by moisture.
· Separates water and electrical circuits, avoiding the impact of humid environments on the electrical system.

Why Use a High-Purity Water Machine
· Stable water quality output, simple testing methods, no need for repeated experiments · High water output, basic models at 10L/H or 20L/H, up to 100L/H · Output water at room temperature, no cooling required, ready for immediate use, reducing experiment analysis time and avoiding secondary contamination during cooling · On-demand water production, avoiding time wasted during transportation and speeding up analytical experiment efficiency · Most importantly, the instrument operates at only 25 watts, significantly more energy-efficient compared to electric thermal water distillers, which typically consume 7–8 kW, often 10 kW, or even 15 kW, reducing daily operating costs · For more comparisons with traditional electric thermal water distillers, see the next section
