Product Overview

Water, for analysis, is a high-purity solvent engineered to meet the stringent demands of laboratory applications. This grade of water undergoes rigorous purification processes, including reverse osmosis, deionization, and ultrafiltration, to eliminate ionic, organic, and particulate contaminants. The result is a product with exceptionally low conductivity (typically < 1 µS/cm) and minimal total organic carbon (TOC) content, ensuring it does not interfere with sensitive analytical techniques such as HPLC, spectroscopy, or electrochemistry. Unlike standard distilled or tap water, analysis-grade water is free from residual chlorine, bacteria, and endotoxins, making it suitable for critical procedures where even trace impurities can compromise results. Its neutral pH and lack of buffering agents ensure compatibility with a wide range of reagents and samples. Whether used for preparing standards, diluting samples, or rinsing glassware, this water provides consistent performance, reducing variability in experimental outcomes. The packaging in high-density polyethylene (HDPE) or borosilicate glass containers further preserves purity by minimizing leaching or environmental contamination during storage.

FAQs

1. What is the difference between analysis-grade water and distilled water?

Analysis-grade water undergoes additional purification steps beyond distillation, such as deionization and microfiltration, to remove ions, organics, and particles. Distilled water may still contain trace contaminants that can affect lab results.

2. Can this water be used for cell culture applications?

While it meets high purity standards, analysis-grade water is not sterile or endotoxin-free unless explicitly labeled as such. For cell culture, use water specifically graded for molecular biology or tissue culture.

3. How should I store analysis-grade water to maintain its purity?

Store the water in its original, tightly sealed container at room temperature, away from direct sunlight and chemical fumes. Avoid transferring to non-lab-grade containers to prevent contamination.

4. Is this water compatible with all analytical instruments?

Yes, its low conductivity and minimal impurities make it suitable for most instruments, including HPLC, GC, and spectrophotometers. However, always verify instrument-specific requirements for water quality.

5. What alternatives exist if analysis-grade water is unavailable?

In emergencies, Type I or Type II lab water (from a purification system) can substitute, but avoid tap or single-distilled water, as they may introduce contaminants.
