Water demineralization system

The LNI demineralizators HLP series are able to supply purified water for instrumental and analytical purposes 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. Our demineralizators are equipped with a microprocessor control and measurement system. The LCD interface provides simple and user-friendly management of all functions on the unit.
