Elga Purelab Ultra Analytic Water Purification System

The PURELAB Ultra water purification unit has been specifically designed to provide a supply of ultrapure water with very low levels of impurities for laboratory, medical and industrial applications.

Feedwater requirements
Source – Originally from potable supply, then pre-treated: Preferably reverse osmosis (RO) or filtered service deionisation (SDI) or distilled.
Fouling Index (max): A 0.2 micron membrane prefilter is recommended for all non-RO feeds
Service Deionisation (SDI) – MΩ-cm: 1 MΩ-cm minimum resistivity at exhaustion
Reverse Osmosis (RO) – µS/cm: Recommended < 30 µS/cm
Free Chlorine: 0.05 ppm max.
TOC Recommended: 50 ppb max.
Carbon Dioxide: 30 ppm max.
Silica: 2 ppm max.
Particulates: Filtration down to 0.2 micron advisable to protect internal and/or point of use filters
