Water demineralization system

The LNI demineralizators HLP UV series are able to supply purified water for instrumental and analytical purposes through the technique of ultraviolet (UV) lamp, matching requirements of every modern laboratories. Conductivity of obtained water does not exceed 0.06 µS/cm, so it is applicable for PN-EN ISO 3696:1999, ASTM, CLSI, FP standards.

The system is the ideal water purification system for AAS, ICP/MS, IC, HPLC, GC instrumental analyses, bacteria cultures, biochemical analyses and for general-purpose research. Our demineralizators are equipped with a microprocessor control, a measurement system and  2 independ water intake points:

  • Second purity class (ISO 3696:1999, ASTM, CLSI).
  • First purity class (ISO 3696:1999, EP)

The LCD interface provides simple and user-friendly management of all functions on the unit.
