Suitable for the most demanding laboratory applications, this system delivers 18.2 megohm-cm water with consistent quality. Gain flexibility with the dispenser that reaches up to 24″ (60cm) from the unit. It can be used on a laboratory bench or on a wall. Integrated feed water monitoring helps to maximize cartridge life. Easily change cartridges within seconds with Aquastop quick-connects.

Dispensing for a variety of tasks

  • New flexible dispenser offers a radius of 24 inches (60cm) from the system for filling larger vessels or glassware washing

Leak Detection

  • Internal leaks can be detected and an error displayed

Integrated feed water monitoring

  • An additional measuring cell monitors feed water conductivity. Any exceeding of the limiting value is immediately displayed to maximize cartridge life.

Online TOC measurement with UV intensity monitoring

  • Real-time TOC monitoring for continual measurement of organic substances present in the water
  • Continuous monitoring of UV intensity removes the risk of false TOC values due to diminished UV intensity
  • Fault message alerts user when the UV lamp intensity is no longer sufficient for accurate TOC measurements

UV Photo-oxidation 185/254nm

  • High performance UV assembly reliably reduces the content of microorganisms and their metabolites
  • UV oxidation also reduces organic compounds in the water to ultra-low levels

Ready-to-use

  • Feed water pressure switch, wall bracket, UV lamp, ultrapure cartridge, sterile filter, all included in one part number
  • Leak detection standard and will alert user to leaks

Measurement of conductivity/resistivity

  • Conductivity cells are carefully calibrated prior to each measurement via built-in reference resistance with cell constants at 0.01 cm-1
  • Temperature measurements are made by a platinum chip sensor with ±0.1°C accuracy

Quick-connect cartridge replacement

  • Aquastop quick-connect capability enables cartridge replacement within seconds even mid-operation

Exact dosing

  • High precision POM draw-off valve for dispensing with sterile filter
  • Electronic dosing for fully automatic volume control of 0.01-65.0L with <2% accuracy

GLP-compliant documentation

  • Real-time clock and code-protected operating system prevents unauthorized changes to system settings
  • RS-232 interface with adjustable send interval for safe data transfer of all measured data, faults, date and time to a PC computer or log printer
  • Digital microprocessor control automatically monitors and stores faults from the last four weeks
  • USP-compliant conductivity measurement with temperature compensation can be switched on or off

Tilting Control Panels for Easy Viewing

  • Ergonomically designed controller tilts for ease-of-use and better visibility
  • Illuminated four-line alpha-numeric display
