Direct-Pure RO Lab Water Systems

The Direct-Pure RO lab water system produces reverse osmosis (RO) water from tap water directly.

  • 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 to extend its usable life.
  • Internal RephiDuo P Pack cartridge further removes oxidants, organics, particles and scaling ions to prevent them from fouling the RO membrane.
  • 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 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.
  • The system recirculates automatically every hour to prevent microbial from growing.
  • The system is equipped with a 30-liter PE tank (upgradeable to a 60-liter) with 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.
  • Large LCD screens on both the water system and the POU dispenser display 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.
  • Pure water can be used in many areas. Here are some typical applications
  • Manual cleaning and glassware rinsing
  • Buffer preparation
  • Glassware washers
  • Humidifiers
  • Water baths
  • Aging tester
  • Autoclave
  • Laboratory animal feed
  • Feed water for ultrapure water systems
