Breaking Down the Features of Elga Labwater Reverse Osmosis Module LC161

Specifications

The Elga Labwater Reverse Osmosis Module LC161 is classified as an INST/EQUIP 1500+ type unit, with catalog number 89204-366 and supplier number LC161. Its primary function is to remove molecular weight compounds from water. This process is achieved by leveraging reverse osmosis principles to intercept and retain specific ions and solutes before they reach the subsequent ion exchange stage.

This pre-filtration capability is crucial because it protects the ion exchange resins from fouling, thereby extending their operational life and maintaining the purity of the final water output. The absence of conventional membrane components in this specific module design means there are no parts prone to clogging and requiring frequent maintenance or replacement, a key selling point for lab managers seeking operational simplicity.

Performance & Functionality

The primary job of the Elga Labwater RO Module LC161 is to act as an advanced pre-filter, specifically targeting molecular weight removal.
