The laboratory high-purity water machine is a water purification device with higher purity than ordinary water purifiers, primarily used for the final rinsing of laboratory glassware, preparation of buffer solutions and chemical reagents, preparation of microbial culture media, pure water for hydrogen generators, indoor humidifiers, high-pressure sterilizers, and drinking water for laboratory animals.
Detailed Introduction
The XINRUI laboratory high-purity water machine is equipped with a microcomputer controller, allowing manual and automatic operation switching. Its control functions include: no water, water full, automatic shutdown, low pressure, overpressure automatic protection, and customizable water output indicators. If the set value is not met, the water is recirculated through a backpressure valve until it meets the requirements, after which the water collection valve can be opened for use. The reverse osmosis (RO) elements, high-purity precision polishing resin, main components, machines, pumps, and instruments of this device can be selected as imported equipment, ensuring reliable quality.
The XINRUI laboratory high-purity water machine is designed with different pre-treatment functions, equipped with various filtration units tailored to different water qualities, such as softening and strong activated carbon adsorption units for high hardness and high turbidity water.
Small microcomputer control function; operated by a small microcomputer, the machine automatically shuts down in cases of water shortage or full water, and automatically runs a rinsing function each time it is started.
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 supervision; it has no electric heating tubes, no scaling issues, and ensures good safety.
Features of the XINRUI laboratory high-purity water machine system:
· Equipped with a silent pump, the system operates without vibration, noise, or electromagnetic radiation, having no impact on the working environment.
· Uses reverse osmosis membranes with stable performance, high desalination rate, and long lifespan.
· Utilizes exchange resin for (ultra) purification columns, offering high exchange capacity and superior 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.
Performance Features of the RS Series High-Purity Water Machine
Includes power indicator, pump operation indicator, low-pressure indicator, and system rinsing indicator functions.
2. Uses imported ion filtration membranes and high-pressure, silent pure water pumps for more reliable operation and broader water quality applicability;
3. Equipped with a system rinsing function: before water production starts each time, the system automatically rinses for 18 seconds, then begins water production;
4. Features system protection function: the device automatically shuts down when water pressure is too low or there is no water, and automatically starts when water supply resumes;
5. In addition to the above features, the RS-II high-purity water machine also has online monitoring functionality, allowing real-time detection of the output water quality, displaying water quality (conductivity online monitoring, higher precision) and temperature on an LCD background.
