Laboratory Ultrapure Water System for Water Filtration RUPC

The Xinrui Laboratory ultrapure water treatment equipment is a water purification device for laboratory use, which removes all solid impurities, salt ions, bacteria, viruses, etc., from water through methods such as filtration, reverse osmosis, electrodialyzer, ion exchanger, and ultraviolet sterilization.
Xinrui Laboratory ultrapure water equipment is widely used in industries such as pharmaceuticals, electronics, chemicals, and biological and chemical laboratories. Laboratory ultrapure water machines typically produce two types of water: pure water and ultrapure water. 
Working Principle of Xinrui Laboratory Ultrapure Water Treatment
The working principle of the laboratory ultrapure water machine is that tap water is pre-treated through precision filter cartridges and activated carbon filter cartridges to filter out particles such as sediment and adsorb odors, making the tap water cleaner. It then undergoes water purification and desalination via a reverse osmosis device. The purified water is stored in a storage tank, meeting the national tertiary water standard, while the wastewater from the reverse osmosis device is discharged. Reverse osmosis purified water undergoes deep desalination through a purification column to produce Grade 1 water or ultrapure water. If there are special requirements, ultraviolet sterilization or microfiltration, ultrafiltration, etc., devices can be added after the ultrapure water stage to remove residual bacteria, particles, pyrogens, etc. Precision filter cartridges, activated carbon filter cartridges, reverse osmosis membranes, and purification columns are materials with relative lifespans. Precision filter cartridges and activated carbon filter cartridges actually protect the reverse osmosis membrane. Product Features of Xinrui Laboratory Ultrapure Water Treatment Equipment
1. Equipped with a complete purification unit, it uses tap water as the input and produces pure water and ultrapure water as output. It produces water of different standards to meet the water needs of various laboratories.
2. The new laboratory ultrapure water machine produces 40 times more ultrapure water per unit than similar imported products, with a water production cost one-fiftieth of other products.
3. If the raw water quality is less than 2000μs and hardness ≦450ppm, the produced water quality can be stably maintained below 5μs/cm, and raw water utilization can reach 60%-80%.
4. Users can also quantitatively draw pure water and ultrapure water. By setting the desired water volume, the ultrapure water machine will automatically produce the appropriate amount of water. The draw volume can be freely set from 10 milliliters to 200 liters, with quantitative accuracy up to ±2ml.
5. Users can store and query data in real-time through the fully intelligent monitoring system, enabling trend analysis. The fully intelligent monitoring system supports multiple languages and multiple users, with separate data recording.
6. True-color LCD touch screen with a graphical human-machine interface enables one-step operation and online information query. All monitoring data of the entire system is collected in real-time and can be viewed online without the need for external computer storage. Data storage capacity can exceed one year.
7. The rational placement of consumables in the purification unit and the plug-and-play of components make calibration, maintenance, cleaning, disinfection, and sampling in system validation easier to perform.
Performance Features of the RUPC Series Ultrapure Water Machine
■ Large color touch screen display and user-friendly interface allow full monitoring of the instrument's working status and real-time data.
■ Fully automatic control, low-pressure alarm shutdown protection, and automatic stop of water production when the water tank is full.
■ Fully automatic microcomputer control system with multi-level menu operation. The controller uses a 32-bit low-power processor as the core, featuring ultra-high computing speed and low power consumption. It integrates analog sensor inputs, switch signal inputs, control outputs, and online monitoring of water conductivity, resistivity, water flow, water pressure, and tank level required for water treatment.
■ Four-digit user password protection, which users can modify themselves.
■ Uses low-voltage 24VDC power supply, complying with safety standards and suitable for humid environments without posing harm to personnel.
■ Features timed standby and automatic shutdown functions. After the shutdown time is reached, all outputs automatically stop, entering shutdown mode.
■ The instrument has a comprehensive alarm prompt function, including low-pressure alarm, raw water quality alarm, pure water quality alarm, ultrapure water quality alarm, and various consumable expiration alarms. When an alarm occurs, the alarm menu interface automatically pops up, displaying current alarm information.
■ Simultaneously monitors three water quality parameters online, real-time monitoring of source water, RO water, and ultrapure water quality.
■ Fully automatic RO membrane anti-scaling rinsing program extends the life of the RO membrane.
■ Ultrapure water circulation system that can be freely started and closed maintains low bacterial contamination levels in the system.
■ Integrated water circulation mode allows users to set the minimum water quality standard. Water that does not meet user requirements enters circulation mode until the water quality is qualified.
■ The instrument features automatic event recording and statistics, including the status and data at the time of the event. After the event is resolved, the controller records the data in the memory for user review later.
■ Special timed water drawing function and quantitative water drawing function.
■ Multiple specifications of water storage tanks are available to meet different needs.
■ Users can choose constant-pressure water tank storage or waterless tank water drawing.
■ Ergonomically designed chassis, compliant with GLP standards.
■ All pipelines are NSF certified, with new quick-connect fittings, making filter column replacement and maintenance more convenient.
■ Original imported nuclear-grade resin and full downflow ultrapurification column design ensure consistently high water quality.
□ Equipped with USB HOST interface and micro-printer interface for real-time storage and printing of historical data.
□ Dual-wavelength (185nm&254nm) imported ultraviolet lamp effectively sterilizes, reduces TOC, and enhances system applicability (optional).
□ Original imported 0.45µm PES polyethersulfone composite membrane terminal sterilizing filter ensures water quality—sterile (optional).
