Culligan Commercial Industrial - Commercial Water Treatment Solutions for Montana, Wyoming and Colorado


Culligan Lab -- Commercial Water Treatment Solutions for Montana, Wyoming and Colorado

Whether you need USP Purified Water, WFI, or high purity water, Culligan Water can provide the water technologies and services that meet your water requirements. Several standards-setting organizations publish standards governing ultrapure water purity. Examples include USP, ASTM, CAP, NCCLS, ANSI and AAMI. Our systems incorporate such technologies as reverse osmosis, deionization, ultrafiltration, ultraviolet systems and absolute cartridge filtration.

Laboratory use

One need of all laboratories is pure water. Without the proper conditions, tests can be contaminated by particulates in the source water. We understand laboratories special needs and concerns regarding the high purity of their water source.

Water quality guidelines for purified water have been established by a number of professional organizations, including the American Chemical Society (ACS), the American Society for Testing and Materials (ASTM), the National Committee for Clinical Laboratory Standards (NCCLS) which is now CLSI, and the U.S. Pharmacopeia (USP). The ASTM, NCCLS, and ISO 3696 classify purified water into Types I-III depending upon the level of purity. These organizations have similar, although not identical parameters for Type I-III water.

Regardless of which organization's water quality norm is used, even Type I water may require further purification depending upon the specific laboratory application. For example, water that is being used for molecular biology experiments needs to be DNase or RNase-free, which requires special additional treatment or functional testing. Water for microbiology experiments needs to be completely sterile, which is usually accomplished by autoclaving. Water used to analyze trace metals may require elimination of trace metals to a standard beyond that of the Type I water norm.

The highest grades of ultrapure water should not be stored in glass or plastic containers because these container materials leach (release) contaminants at very low concentrations. Storage vessels made of silica are used for less demanding applications and vessels of ultrapure tin are used for the highest purity applications.
