Water Purifier LB-50WP

Name: Water Purifier LB-50WP
Brand: Labotronics
SKU: LB-50WP
Rating: 5 (559 reviews)

Labotronics Water Purifier LB-50WP produces 15 L/h of purified water, delivering ultrapure water at 18.25 MΩ·cm resistivity with TOC below 10 ppb. The RO stage removes 95–99% of divalent ions and over 99% of organics above 200 Dalton. As a compact laboratory water purification system, it dispenses RO water at up to 2 L/min and ultrapure water at up to 1.5 L/min through separate front outlets. It filters feed water through reverse osmosis and further purification to supply both RO and ultrapure water from one system.
