Product Overview
Nitric acid (HNO₃) at 67-70% concentration is a highly pure reagent-grade solution designed for demanding laboratory applications where precision and reliability are critical. This BAKER INSTRA-ANALYZED™ Plus grade ensures minimal impurities, making it suitable for trace metal analysis, sample digestion, and other analytical procedures requiring strong oxidizing properties. The high concentration provides efficient reaction kinetics, reducing preparation time while maintaining consistency across experiments. Packaged in a 500 ml bottle, this nitric acid solution offers convenience for both small-scale and bulk laboratory workflows. The reagent is stabilized to prevent degradation, ensuring long-term storage stability without compromising performance. Its low heavy metal content and strict quality control during production make it a preferred choice for applications where contamination could skew results. The solution is compatible with most laboratory glassware and standard analytical instruments, though proper handling protocols should be followed due to its corrosive nature.
FAQs
1. What is the shelf life of this nitric acid solution when stored properly?
When stored in its original tightly sealed container at room temperature, away from direct sunlight and moisture, this nitric acid solution maintains its specified purity for up to 24 months from the date of manufacture. Always check the label for the exact expiration date.
2. Is this nitric acid compatible with plastic containers for dilution?
This concentrated nitric acid should only be diluted in containers made from borosilicate glass or PTFE-coated materials, as it can degrade most plastics. Always add acid to water slowly to prevent violent reactions.
3. What alternatives exist for applications requiring lower nitric acid concentrations?
For applications needing diluted solutions, you can prepare working concentrations from this stock or opt for pre-diluted nitric acid solutions available at 10%, 20%, or 30% concentrations, depending on your specific requirements.
4. How should this nitric acid be disposed of after use?
Neutralize with a compatible base like sodium hydroxide or sodium bicarbonate until the pH reaches 6-8, then dilute with water before disposal according to local environmental regulations. Never pour concentrated acid down drains.
5. What certifications or quality documents accompany this product?
This BAKER INSTRA-ANALYZED™ Plus reagent comes with a Certificate of Analysis (CoA) detailing its purity, heavy metal content, and other critical parameters, ensuring traceability and compliance with analytical standards.
