Equipment used for water purification and
distillation includes deionized (DI) water systems, water distillers, reagent-grade water
systems, and laboratory filters.
DI and distilled water are the most common types
of purified water used in the lab, but techniques also used to produce high-purity water include:
- Carbon filtration
- Ion exchange
- Reverse osmosis (RO)
- UV oxidation
Ultrapure water systems are used to produce Type I water, 18.2 MO cm at 25
°C, with low levels of TOC.
How is Pure and Distilled Water Used in the Lab?
Purified water is a necessity in PCR, DNA sequencing, protein research, chromatography,
media prep, in the formulation and manufacture of pharmaceuticals, in molecular biology, and
in the semiconductor industry.
