We are experts in designing, implementing and maintaining high purity water systems for critical and non-critical appliactions.

We offer over 16,000 products for use in just about any purification application including :

• Complete lab and process water systems,
• Replacement filters for most laboratory water systems,
• Lab process filters
• Laboratory equipment of all types.

Because water purity is so important, several professional organizations have established water quality standards. Some of these influential groups are the American Chemical Society (ACS), the American Society for Testing and Materials (ASTM), US Pharmacopeia (USP), and the National Committee for Clinical Laboratory Standards (NCCLS). NCCLS specifies three types of water--I, II, and III--and water intended for Special Purpose use.

What are the contaminents

Contaminant is any substances you do not want in your water. These are also called impurities. Some common contaminants found in water are particulates, dissolved inorganic (solids and gases), dissolved organics, microorganisms, DNA, RNASE and pyrogens.

How can I get rid of contaminants?

There are a number of different ways to decontaminate (or purify) water.coarse filtration activated carbon filtration , reverse osmosis, Deionization, organic adsorption, microporous filtration, ultrafiltration, ultraviolet oxidation anddistillation are all technologies used in combination to production of laboratory, pharmaceutical or ultra pure water.

How do I know what method to use?

You need to consider your application, the quantity of the water you need for your application and the existing condition of your feed water. If you are performing HPLC, Atomic Absorption, Mass Spectrometry or Gas Chromatographic Analyses, you will probably need a system that uses activated carbon, organic absorption, and deionization technologies. If you need bacteria-free water, then microporous filtration or ultrafiltration are better methods for your application. Given this information a water purification system can be matched to your needs. A call to one of our knowledgeable technical representatives may be helpful in deciding which system is the best one for your company.
