-
SPECTRUM Pure Cartridge:
- The SPECTRUM Pure Cartridge is specifically designed for the WSU 2 plus device range to produce ultrapure water with a conductivity > 18 MΩ.
- 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 > 18 MΩ.
- 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.
