YETUO YTUP-20 Basic Ultrapure Water Purifier
Model: YTUP-20
Product Overview:
The YETUO YTUP-20 Basic Ultrapure Water Purifier features dual RO pure water and UP ultrapure water outlets, with a water production capacity of 20 L/h. It provides both reverse osmosis pure water and ultrapure water for different laboratory applications. UP water resistivity is 18.25 MΩ·cm at 25°C, with total organic carbon (TOC) below 10 ppb. RO water TDS is less than 4% of the feed-water TDS. The system adopts a multi-stage PP+UDF+CTO+RO+DI+UP purification process and is equipped with LCD online water-quality monitoring, automatic alarms and automatic RO membrane flushing. It is suitable for laboratory applications including environmental analysis, physical and chemical experiments, high-precision instrument analysis, molecular biology, cell culture, protein purification and amino acid analysis.

YETUO YTUP-20 Basic Ultrapure Water Purifier — Product Features
1. Fully Automatic Control System
Automatic pressure sensors and microcomputer control enable automatic purified water production. The system features a user-friendly operation and display interface with audible and visual alarm functions.
2. Quick-Connect Piping and Flexible Water Supply
The entire piping system adopts quick-connect fittings and comes standard with an external equipment water-supply outlet. External water storage tanks can be added, with various capacities available to meet different requirements.
3. NSF-Certified Piping
All pipelines are NSF-certified and adopt a modular quick-connect design, making installation, maintenance and servicing more convenient.
4. Adaptable Feed-Water Pretreatment
The system has relatively low feed-water quality requirements. Its carefully designed pretreatment system can process different types of raw water from various regions.
5. High Water Production and Low Operating Costs
High water production capacity, long consumable service life and low operating costs support economical daily operation.
6. Multiple Alarm Functions
The system provides no-water alarms, full-tank alarms and ultrapure water quality alarms. The ultrapure water alarm threshold can be freely configured.
7. Automatic RO Membrane Flushing
The fully automatic RO membrane anti-scaling flushing program helps reduce scale buildup and extend the service life of the RO membrane.
8. Multiple Safety Protection Features
The system adopts water-electricity separation and is equipped with overcurrent protection, inlet protection and anti-burst safety devices to provide comprehensive protection during operation.
9. Portable TDS Test Pen
The portable battery-powered TDS test pen can measure the total dissolved solids (TDS) of tap water and RO water at any time, providing an approximate indication of conductivity.
10. Online Water-Quality Monitoring
A high-brightness backlit LCD monitoring instrument provides real-time monitoring of resistivity, conductivity, TDS and water temperature, with a stated measurement accuracy of 0.01 MΩ·cm.
11. Electronic-Grade Mixed-Bed Resin
Electronic-grade mixed-bed resin and a large-capacity purification tank help maintain stable water quality and a consistent water supply.
12. Optional Terminal Sterilizing Filter
An optional pharmaceutical-grade terminal capsule sterilizing filter is available to ensure sterile water quality.
