  • LOGIN FOR MORE INFO

The Large Direct-Pure EDI lab water system produces Type II water from tap water directly. Resistivity of product water is above 5 MΩ·cm (25 ℃), which meets or exceeds Type Ⅱ water quality standard defined by ASTM, CAP, CLSI and ISO 3696/BS 3997, the European and U.S. Pharmacopoeia. The System is designed for users who need 400 to 1800 liters of Type II water per day.

  • 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
  • For ophthalmics
