Direct-Pure UP Ultrapure & RO Lab Water Systems

The Direct-Pure UP Ultrapure & RO Lab Water System is an integrated system that produces ultrapure and reverse osmosis (RO) water from tap water directly. Quality of ultrapure water meets or exceeds ASTM, CLSI, CAP, and ISO Type I water standards.
- Electrical and water compartments are completely segregated, thus safer to operate.
- The fully automated control system contains pre-rinse, RO membrane fouling preventing flush, RO membrane and cartridge 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.
- Two sets of dual-column purification cartridges work sequentially to ensure thorough removal of ions and organics in water.
- The system recirculates automatically every hour to prevent microbial from growing
- Resistivity is measured by a high-precision resistivity meter.
- The system is equipped with a 30-liter PE tank (upgradable to a 60-liter) and a liquid level sensor.
- A 0.2 μm final filter or ultrafiltration filter (optional) removes final contaminants.
- RephiLe can provide full document support to meet users’ GMP, GLP, FDA and other certification requirements.

* If water hardness is less than 180 ppm, RephiLe suggests using RephiTEKT RW50211KT.

If water hardness is greater than 180 ppm, RephiLe suggests using an additional water softening device to protect the RO membrane in your system.

** Product water quality may vary depending on local feed water conditions.
