Product Overview
Distilled water LR is a high-purity solvent essential for laboratory applications where contamination must be minimized. Produced through a rigorous distillation process, this water is free from dissolved solids, ions, and organic impurities, ensuring reliable and consistent results in experiments. Its LR (Laboratory Reagent) grade designation indicates suitability for general lab procedures, including reagent preparation, dilution, and rinsing glassware. The absence of additives or stabilizers makes it ideal for sensitive analytical techniques where even trace impurities can interfere with accuracy. Packaged in durable, leak-proof containers, this distilled water maintains its purity during storage and handling. Whether used in qualitative analysis, microbiological studies, or routine lab maintenance, its standardized quality guarantees reproducibility across experiments. The 5 L pack size offers convenience for frequent use while reducing the need for repeated procurement. Store in a cool, dry place away from direct sunlight to preserve its integrity.
FAQs
1. What is the difference between distilled water LR and deionized water?
Distilled water LR is produced by boiling and condensing steam to remove impurities, while deionized water undergoes ion-exchange to eliminate charged particles. LR grade is suitable for general lab use, whereas deionized water is preferred for applications requiring ultra-low conductivity.
2. Can this distilled water be used for cell culture or molecular biology?
LR-grade distilled water may contain trace contaminants unsuitable for cell culture or molecular biology. For these applications, use sterile, nuclease-free, or cell culture-tested water to prevent interference with biological processes.
3. How long can distilled water LR be stored before use?
When stored in a tightly sealed container away from light and heat, distilled water LR remains stable for up to 12 months. However, check for cloudiness or particulate matter before use, as prolonged storage may risk contamination.
4. Is this water compatible with HPLC or spectroscopy?
LR-grade distilled water may not meet the purity requirements for HPLC or spectroscopy, which demand ultra-low organic and particulate levels. Opt for HPLC-grade or spectroscopy-grade water for these techniques to avoid baseline noise or instrument damage.
5. What alternatives exist for applications requiring higher purity?
For applications needing stricter purity, consider Milli-Q water, ASTM Type I water, or ultrapure water (UPW) systems. These options provide lower conductivity, TOC, and bacterial endotoxin levels compared to standard distilled water LR.
