Water Purification Systems

  1. What is Pure Water?

    What is Pure Water?

    To understand PURE water, let's first discuss all of the impurities that can contaminate sensitive experiments, then we'll address how Thermo Scientific Barnstead water purificiation systems are engineered to remove them.  The table below illustrates the common impurities that impact the applications listed.

    H2O Select Analysis Kit - To Evaluate and Recommend

    Based on the results of a FREE Thermo Scientific Select Analysis, we will recommend the best water system for your application. We do all the thinking for you! Using our unique H20 SELECT* water analysis program, choosing the right water purification system is made simple. After reviewing the questionnaire included in each sample kit, and performing an analysis of the feed water sample you submit, our water experts will recommend the appropriate equipment and consumables based on your feed water quality, laboratory applications, daily water demand, and budget. The output of this FREE, no obligation service includes a brief summary report of the results of the feed water testing, a recommendation of the system we think will best meet your needs, and an estimated life expectancy of consumables to help you project system operating costs.

    Reverse Osmosis Water Systems

    Reverse osmosis is the most economical method to remove up to 99% of your water's impurities.  The RO membrane is semi-permeable with a thin microporous surface that rejects virtually all dissolved materials including dissolved inorganic solids, organics, particles and microorganisms. RO water is versatile. RO water can be used to prepare microbiological buffers and chemical reagents.  Additionally, it is a great option for use in general laboratory equipment, such as water baths, humidifiers, and autoclaves.  RO water is also an excellent pretreatment choice for our Type 1 systems.

    What is Type 2 Water?

    Pure water for a wide range of applications. Pure water is an essential part of creating chemical reagents, microbiological buffers and media that are consistently pure.  It is also an excellent source of water for glassware washing, and as feed water for laboratory equipment such as autoclaves, laboratory dishwashers, and water baths.  It is also a recommended source of pretreated water for your Type 1 ultrapure system.

  7. What is Type 1 Water?

    What is Type 1 Water?

    What does type 1 water mean? Reagent water has quantitative specifications that describe the level of purity for the water.  These specifications have been described by ASTM (American Socity for Testing and Materials) D1193, ISO (International Organization for Standardization) 3696, and CLSI®-CLRW. (Clinical and Laboratory Standards Institute-Clinical Laboratory Reagent Water). The most commonly used standards, ASTM D1193-6, are summarized in the tables below.
