Water plays an essential role across industries, whether as a solvent, raw material, or for cleaning equipment and products. CARLO ERBA Reagents offers a range of high-quality, purified water types tailored to meet the specific needs of diverse applications.

Understanding Purified Water Types

The two primary categories of purified water are demineralized and distilled water. Each type has unique characteristics, making it suitable for different industrial uses:

Demineralized Water

Demineralized water is free or almost free of ionized impurities, such as cations (like calcium, sodium, magnesium) and anions (like chloride or sulfate). However, the processes used to produce it do not remove uncharged molecules, such as organic substances or bacteria.

It is produced through multiple purification techniques, which may include:

• Reverse Osmosis : This process is based on the principle of a semi-permeable membrane. When two liquids of different concentrations are separated by this membrane, the less concentrated liquid passes through the membrane to mix with the other. By applying a pressure greater than the natural osmotic pressure, the water passes through the membrane in the opposite direction, leaving behind the dissolved solids, which purifies the water.

• Electrodeionization:This technique combines reverse osmosis and ion exchange. Modules containing cationic and anionic resins are placed between selective membranes. Using an electric current, the ions captured by the resins are directed towards the membranes. This process, when coupled with reverse osmosis pre-filtration, makes it possible to achieve very high resistivity of demineralized water.

  

• Membrane Filtration : Impurities are filtered out as water passes through specialized membranes.

Distilled Water

Produced by heating and condensing water vapor, distillation removes not only ionized impurities but also microorganisms, offering very high purity levels ideal for applications where bacteria-free water is critical.

Why choose CARLO ERBA Reagents ?

As experts in solvent purification, we have the expertise and facilities to produce high-quality, demineralized water using advanced techniques. Our water undergoes additional bacteriological treatments, ensuring the highest levels of purity for our clients.

Our Advantages

• Flexibility : We offer various grades and packaging options, from 1L bottles to large IBCs.
• Quality : Qualified processes and pharmaceutical-grade water options enable us to meet strict specifications, with endotoxin control available upon request.
• Risk Control: We guarantee consistent quality through weekly bacteriological checks, disinfection cycles, and stringent monitoring. Unlike water produced by a standard lab osmosis unit, our water meets defined specifications for industrial reliability.

Our Product Range

Pure Water

• Analytical Grade : RPE and for Ph. Eur Ch 4.1.1 analysis

• Liquid Chromatography : HPLC gradient, LC-MS, UHPLC-MS, or acidified (e.g., 0.1% TFA) for specific applications

• Gas Chromatography : Headspace-compatible options

• Trace Metal Analysis : Available at ppb (Superpure) and ppt (Ultrapure)

Water mixtures :

We also produce water-based mixtures and dilutions, which can include corrosive agents (acids or bases), salts, or other liquids.
Custom formulations are available alongside catalog options.

Packaging Options

Our packaging includes 1L plastic or glass bottles up to large plastic IBCs.
Note: To prevent leaching, our glass bottles for HPLC-grade water and higher are DFE-coated.

Importante Information

We do not produce PPI (Preparation for Injectable) water, and although ozonated, it is not sterile.
