Scientific Solutions

In today's laboratories, the availability of Pure Water is essential, and while domestic consumers consider tap water to be "pure", laboratory scientists regard it as highly contaminated. Analytical and experimental scientists are concerned with elements and compounds at concentrations in parts per billion (ppb) range or lower as many of these contaminants can have a negative effect in applications through their interaction with other substances, including the substance under analysis.

Scientists perform a vast range of applications in many different kinds of laboratories. Therefore, different grades of water must be purified and utilised to match the required procedures or appliances. Water is one of the major components in many applications, but the significance of its purity is often not recognised.

There are many water quality standards published throughout the world however only a few are relevant to specific research applications. This has resulted in the adoption of broad generic classifications defined by measurable physical and chemical limits.  

Type III

Is the grade recommended for non-critical work which may include glassware rinsing, water baths, autoclave and disinfector feed as well as environmental chambers and plant growth room. System can be used to feed Type I system.

Type II

Is the grade for general laboratory applications. This may include media preparation, pH solutions and buffers and certain clinical analysers. It is also common for Type II systems to be used as a feed for a Type I system.

Type II+

Is the grade for general laboratory applications requiring higher inorganic purity.

Type I

Often referred to as ultra pure, this grade is required for some of the most water critical applications such as HPLC mobile phase preparation, as well as blanks and sample dilution for other key analytic techniques such as GC (Gas Chromatography), AAS (Atomic Absorption Spectrophotometry) and ICP-MS (Inductively Coupled Plasma Mass Spectrophotometry). Type I is also required for molecular biology applications as well as mammalian cell culture and IVF.

Type I+

Goes beyond the purity requirements of Type I water.

Customer Quote

"Clinical analysis demands the highest possible levels of quality & accuracy each and every time. We need the assurance that the water we rely on is of the best possible quality for each stage of our analysis. ELGA have consistently delivered on the criteria we work to."
