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.

  • Type I ultrapure water and RO water are produced directly from tap water in one single system.
  • Electrical and water compartments are completely segregated, thus safer to operate.
  • System automatically reduces feed water pressure to within working range.
  • Pre-filtration system removes most particles, chlorine and organic compounds to protect RO membrane and EDI module to extend their usable lives.
  • Internal RephiDuo P Pack cartridge further removes oxidants, organics, particles and scaling ions to prevent them from fouling the RO membranes and the EDI module.
  • RO membrane removes over 99% large molecules and particles as well as 95% ions in water.
  • The automatic bypath sends the RO water to the drain if it does not meet preset quality standard.
  • The RO drain water is reused to increase the water yield. It is more environmentally friendly.
  • System automatically rinses a new RO membrane. User does not need to set special rinse program for a new RO membrane.
  • 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.
  • Ultra purification cartridge is filled with LeFilTM and OrganeFilTM media to remove trace ions and organics.
  • Built-in 185/254 nm dual wavelength lamp reduces TOC level in ultrapure water.
  • The system recirculates automatically every hour to prevent microbial from growing.
  • The system is equipped with a 30-liter PE tank (upgradable to a 60-liter) and a liquid level sensor.
  • Tank vent filter has CO2 scavenger to remove airborne contaminants, including carbon dioxide and keeps water in the tank at best quality possible.
  • A 0.2 μm final filter or ultrafiltration filter (optional) removes final contaminants.
  • Large LCD screen on the water system displays critical information for instant access of system operation and performance parameters.
  • 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.
