Xinrui Laboratory ultrapure water treatment equipment is a water purification device for laboratory use. It removes all solid impurities, salt ions, bacteria, viruses, etc., from water through methods such as filtration, reverse osmosis, electrodialyzers, ion exchangers, and UV 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 a laboratory ultrapure water machine involves pretreatment of tap water 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 reverse osmosis for water purification and desalination. The purified water is stored in a storage tank, meeting the national三級 water standard, while the wastewater from the reverse osmosis system 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, UV sterilization or microfiltration, ultrafiltration, etc., are added after ultrapure water production 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 feed water 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 the ultrapure water output of similar imported products, with a water production cost one-fiftieth of other products.
3. If the feed water quality is less than 2000 μS and hardness ≦450 ppm, it ensures stable output water quality below 5 μS/cm, with feed water utilization rates reaching 60%-80%.
4. Users can also quantitatively draw pure water and ultrapure water. Once the water volume is set, the ultrapure water machine automatically produces the appropriate amount of water. The draw volume can be freely set from 10 ml to 200 liters, with quantitative accuracy up to ±2 ml.
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 multi-language modes and multi-user operation, 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 external computer storage. Data storage capacity exceeds one year.
7. Reasonable placement of consumables in the purification unit and plug-and-play components make calibration, maintenance, cleaning, disinfection, and sampling during system validation easier.
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, automatic stop of water production when the 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 can be modified by the user.
■ Uses low-voltage 24V DC power supply, complies with safety standards, suitable for humid environments, and poses no harm to personnel.
■ Equipped with timed standby and automatic shutdown functions. After the shutdown time is reached, all outputs automatically stop, entering shutdown mode.
■ The instrument has comprehensive alarm functions, including low-pressure alarm, feed 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.
■ Simultaneous online monitoring of three water quality parameters, real-time monitoring of source water, RO water, and ultrapure water quality.
■ Fully automatic RO membrane anti-scaling flushing program extends RO membrane life.
■ Ultrapure water circulation system that can be freely started and stopped maintains low bacterial contamination levels.
■ Integrated water circulation mode allows users to set minimum water quality standards. Water that does not meet user requirements enters circulation mode until it meets standards.
■ The instrument has automatic event recording and statistics functions, including the status and data at the time of the event. After the event is resolved, the controller records the data in memory for future user review.
■ Special timed water drawing and quantitative water drawing functions.
■ Multiple specifications of water storage tanks are available to meet different needs.
■ Users can choose constant-pressure tank water storage or water drawing without a water tank.
■ Chassis designed with ergonomics, 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, fully descending flow ultrapurification column design, ensuring excellent water quality at all times.
□ Equipped with USB HOST interface and micro-printer interface for real-time storage and printing of historical data.
□ Dual-wavelength (185nm & 254nm) imported UV lamp effectively sterilizes, reduces TOC, and enhances system applicability (optional).
□ Original imported 0.45μm PES polyethersulfone composite membrane terminal sterilization filter ensures sterile water quality (optional).
