Comparing bottled water and a point-of-use system

Choose bottled molecular-biology water or a point-of-use polisher for PCR, chromatography, or cell-culture reagents, and see how each one fails after it leaves

Conductivity TOC and what each detects

Conductivity and resistivity report ions. TOC reports oxidisable organic carbon. Choose the test that matches the blank your assay can actually fail.

Laboratory water types and where they fail

Resistivity, organic carbon and endotoxin answer different questions. A water grade fails when the assay cares about a contaminant the meter cannot see.

Microbial growth in a water polisher

Define biofilm, colony-forming units, endotoxin, endotoxin units, a point-of-use filter, and a dead leg so a clean resistivity reading is not mistaken for clean
