Understanding Water Purity Levels
In scientific and regulated environments, the quality of water used can significantly impact the accuracy of experiments, the reliability of results, and compliance with stringent standards. Recognising this, LAF tech is proud to partner with stakpure, a German-engineered leader in pure and ultrapure water systems.
But what are the options?
Laboratory water is categorised based on its purity, with classifications such as Type I, II, and III:
Required for highly sensitive applications such as HPLC, ICP-MS, and molecular biology. It has a resistivity of 18.2 MΩ·cm and TOC <10 ppb, ensuring minimal interference in analytical results.
Suitable for general laboratory applications, including buffer preparation and feeding autoclaves. It has a resistivity of ≥1 MΩ·cm and a TOC content of less than 50 ppb.
Typically produced by reverse osmosis, this water is used for non-critical applications like glassware rinsing and feeding water baths.
Stakpure's Advanced Purification Technology
Stakpure’s systems integrate multiple purification stages to achieve the desired water quality:
Pre-treatment: Removal of particulates, chlorine, and organic compounds using activated carbon filters and sediment filters.
Reverse Osmosis (RO): Eliminates up to 99% of dissolved salts, organic compounds, and microorganisms.
Electrodeionisation (EDI): Combines ion exchange resins and electricity to remove ionised species, ensuring continuous deionisation without chemical regenerants.
Ultraviolet (UV) Oxidation: Degrades organic compounds and inactivates microorganisms, reducing TOC levels.
Ultrafiltration (UF): Removes endotoxins, nucleases, and other macromolecules, crucial for molecular biology applications. (stakpure.de)
Polishing: Final purification steps, including mixed-bed ion exchange and 0.2 µm filtration, to achieve the highest purity levels.
