Duo™-i Type 3 and Type 1 | RO and Ultrapure Water System

Efficient Dual Quality Water Purification System

Type 3 / RO Water Applications

Type 3 water is required for sensitive laboratory applications:

• Hydroponics
• Steam Generators
• As feed water for:
  - Type I ultrapure water systems
  - Automated glassware washers
  - Autoclaves

Type 1 / Ultrapure Water Applications

Type 1 Water from this system meets or exceeds Type 1 water standards as specified by ASTM, CAP, ISO 3696, CLSI, JIS K0557 and high-purity water as described in USP, EP and ChP. Type 1 water is required for critical laboratory applications such as:

• Analytical instrumentations: HPLC, UPLC, AA, ICP, LC-MS, GC-MS, ICP-MS, Ion Chromatography, Electrochemistry, Particle Counter, TOC Analysis
• Life science instrumentations: PCR, DNA sequencing, electrophoresis
• Preparations for cell culture, molecular biology and monoclonal antibody applications

System Features

Integrated Reverse Osmosis Technologies

• Patented 2-stage reverse osmosis technology enables superior and stable output quality
• Output conductivity of 5μs/cm is typical from tap water as challenging as 2,000μs/cm
• Superior RO purification with up to 99% ion rejection rate which improves the life expectancy of cartridges and final filters

Flexible dispensing options

Draw Type 3 water in three ways: directly from the reservoir tap, from a flexible dispenser on the system, or from two additional remote dispensers each placed up to 2.9m away (up to 5.8m in serial)

• Real-time Resistivity and Total Organic Carbon (TOC) levels are monitored and displayed on screen
• Dispense rates of >2 L/min from the tap, or up to 2 L/min from the remote dispenser, ensure >120 liters availability for peak hour usage
• Routine system control functions are fully available on the dispenser including a “Print Report” function for Good Laboratory Practices. This allows for maximum bench space utilization as the main system, pre-treatment module and reservoir can be placed under the bench

Draw Type 1 water either directly from a flexible dispenser on the system, or from two additional remote dispensers each placed up to 2.9m away (up to 5.8m in serial). Each dispenser may also be placed on a stand or used freely from up to 0.8m away.

• Real-time Resistivity and Total Organic Carbon (TOC) levels are monitored on the display
• Choice of dispensing modes:
  - Constant flow rates with choices from drops to 2.0L/min
  - Fixed volume (up to 90L)
• Routine system control functions are fully available on the dispenser, including “Print Report” function for Good Laboratory Practices. This allows maximum bench space utilization.

Choice of final filters to match your application needs:

• 0.2μm for bacteria removal
• 0.1μm for particulate removal
• Positively-charged capsule for RNases, DNases and endotoxin removal

Integrated controls

Enable Type 3 water to be always available from the reservoir. Water quality is maintained by UV sterilization and vent filtration to minimize
re-contamination from CO2, volatile organic compounds, bacteria and particles.

Integrated Pre-treatment Module

• Integrated controls on inlet water pressure and monitoring of flow rates to optimize system operations. Optional booster pump available
• 3.2” screen displays color-coded operating condition of each component
• Choice of cartridges based on local tap water condition:
  - Silt Density Index (SDI)
  - Chlorine
  - Bacterial
• IC chip onboard the cartridges ensures proper installation and operation
• Easy cartridge replacement

Integrated Reservoir

• Reservoir controls such as UV exposure timing and conductivity levels are integrated with the main system
• Vent filter is fitted to reduce environmental contaminants such as CO₂, particles, bacterial and volatile organic compounds
• Dual level sensing mechanism offers additional system protection when water exceeds critical levels (10% and 110%)

Integrated Polishing Technologies

• Choice of deionization cartridges with IC tag to meet your applications:
  • Standard high volume polishers
  • Low TOC for sensitive analysis
  • Low Boron for ICP analysis
• UV technology offers effective oxidation of organic materials and enables rapid water quality recovery upon system restart
• Total Organic Carbon (TOC) monitoring option offers reliable real time results

Integrated System Monitoring

• Complete monitoring of conductivity, pressure and flow rate at up to 6 stages
• System conditions are visibly displayed with graphics and color codes
• Automated disinfection processes ensure complete system sanitization
• Multiple data management options including RS232 and SD card

Integrated Water Leak Protection

• Unique base cover channels any potential water leak to a drainage point. Leak sensor located at the drainage point will detect presence of a water droplet 1mm from the discharge point
• An additional leak sensor may be placed inside the pre-treatment module

7” touch screen offers friendly and intuitive user experience:

• “Touch” sequences similar to smart phones encourage new users to operate with ease
• Color-coding (Red, Amber, Blue) and Flashing indicators offer guidance to any non-routine actions needed and their urgency/criticality
• Unmatched “width” and “depth” of system control

Operating Screen provides comprehensive operating parameters at one glance:

• Water quality data from dual output: conductivity, TOC, temperature and dispensing rate
• Reservoir water level
• On-line alerts

Displayed languages are selectable in English, Chinese, Japanese, or Korean

Monitor screen provides scientific criteria for consumables management based on:

• Flow rate and pressure sensing
• Usage time
• Water quality monitoring
