Direct-Pure Water System, EDI 5
Click to enlarge image(s)

The Direct-Pure EDI lab water system produces Type II water from tap water directly. Resistivity of the product water is above 5 MΩ·cm at 25℃, which meets or exceeds Type II water quality as defined by ASTM, CAP, CLSI and ISO 3696 / BS 3997 and also complies with the Purified Water requirements from the European and U.S. Pharmacopoeia.
- The system incorporates the best in class Siemens EDI module to deliver high quality Type II water consistently at relatively lower cost.
- Automatic water quality control programs ensure EDI product water meeting or exceeding Type II water requirements.
- The fully automated control system contains pre-rinse, RO membrane fouling preventing flush, RO membrane life monitoring as well as many other programs for convenient operation.
- The pre-rinsing program starts automatically when a new RO membrane is installed so there is no need for users to set up additional cleaning procedures.
- Users can set water dispensing time for easy water collection.
- The system is equipped with a 30-liter PE tank (upgradable to a 60-liter) and a liquid level sensor and a tank vent filter with CO2 scavenger to prevent EDI water from carbon dioxide contamination. 
- RephiLe can provide full document support to meet users’ GMP, GLP, FDA and other certification requirements.
Main Applications:
- Type II Pure water can be used in many areas. Some of the typical applications are.
- Preparation of bio-reagents
- Preparation of culture media
- Preparation of solution for chemical analysis such as HPLC, ICP etc.
- For clinical analyzers
- Feed water for ultrapure water systems
- Medical device and equipment rinsing
- For serum and blood fractions

 Feed Water Quality
