Technical specifications WSU 2 plus
• Economical and resource-saving production of ultrapure water for laboratory use and in-vitro diagnostics
• Simple and quick (< 1 min.) consumables replacement by the user
• Simple and safe sampling point
Operating principle
Multi-stage ion exchanger with UV disinfection reverse osmosis module and sterile filter units
Up to 10 times longer resin service life compared to conventional water treatment systems without a reverse osmosis module.
Output Conductivity
TOC-value (Total Organic Carbon)
Microbiological retention
<1.0 µS/cm
<500 ppb
<1 cfu/ml
Highlights
• Web-based interface for real-time data monitoring
• Mobile frame, trolley
• Recommended: Pre-filtration unit
- Pre-filtration unit for decent water quality, mountable on trolley
- Pre-filtration unit for pure and very pure water quality, on trolley
• Leakage sensor included
• WSU 2 plus: 70 L/h or 120 L/h withdrawal volume,
• WSU 2 mini: 20 L/h withdrawal volume
• Meets the Specification of all cobas instruments by Roche Diagnostics
• Temperature-compensated conductivity measurement
• Dynamic maintenance intervals depending on consumption and water input quality
(The device displays when something needs to be changed)
• Independent emergency supply function with conductivity monitoring
• 10 L reservoir tank included (up to 10 L of ultrapure water can be extracted, after failure of water or power supply)
• Quick exchange of consumables (resin, polisher, filters, UV-lamp) < 1 min.
• 10 times longer resin and polisher lifetime due to reverse osmosis membrane (compared to conventional systems)

-
Spectrum Pure Cartridge:
- The Spectrum Pure Cartridge is specifically designed for the WSU 2 plus device range to produce ultrapure water with a conductivity >18MOhm.
- The Spectrum Pure Cartridge is ready to use filled with a strongly acidic cation exchanger and a strong alkaline anion exchanging resin.
-
Spectrum Ultra Pure Cartridge:
- The Spectrum Pure Cartridge is specifically designed for the WSU 2 plus device range to produce ultrapure water with a conductivity >18MOhm.
- The Spectrum Pure Cartridge is ready to use filled with a strongly acidic cation exchanger and a strong alkaline anion exchanging resin. Both have a monodisperse particle size distribution based on a styrene divinylbenzene copolymer.
All water-wetted parts are made out of plastic or stainless steel, so that the WSU 2 plus can be operated with tap water as well as with deionized water.
