Watrex Praha, s.r.o. products

Well-proved NW series water purification system can be directly connected to water tap, providing you with optimum convenience. NW series water purification system meets all eminent international water quality standards like: ASTM Type 1, NCCLS Type 1 and ISO 3696 Type 1.

The ROP system produce high quality pure water of high resistivity and low TOC. The system`s product water is stored in a water tank with anti-contamination design and is ideal for routine laboratory applications. Combining several purification technologies including Reverse Osmosis, Deionization and UV-sterilizer, the ROP system removes all types of water contaminants (typically 95%- 99 %). The built in UV lamp is ideal for applications that require low bacteria levels. The consumable includes the pre-treatment, reverse osmosis membrane and ion-exchange resin. LCD display shows the system status,including the conductivity in uS/cm or the resistivity in M(Ohm)-cm , temperature and water level in water tank.

Column heater with separate electronic control module.
