Product Overview
This 0.1N potassium hydroxide (KOH) volumetric solution in ethanol represents a premium-grade analytical reagent designed for applications requiring exceptional precision. Formulated using BAKER ANALYZED™ standards, it delivers certified normality with minimal variability, ensuring reliable results in critical laboratory procedures. The ethanol-based solvent system enhances solubility for organic compounds while maintaining solution stability over extended periods. Each batch undergoes rigorous quality control to meet strict titrimetric specifications, with traceability documentation available upon request. The solution’s low carbon dioxide absorption characteristics prevent concentration drift during storage or use. Packaged in high-density polyethylene containers with tamper-evident seals, it maintains integrity during transport and storage. The reagent’s clarity and absence of particulate matter eliminate the need for filtration before use. Compatible with automatic titrators and standard glassware, this solution minimizes calibration requirements while maximizing reproducibility. Its neutral packaging prevents leaching of contaminants that could affect analytical accuracy. The ethanol base also provides excellent miscibility with organic samples, making it particularly suitable for non-aqueous titrations where water-based KOH solutions would be ineffective.
FAQs
1. What is the shelf life of this 0.1N KOH ethanol solution when unopened?
The unopened solution maintains its certified normality for 12 months from the date of manufacture when stored at room temperature in its original container. After opening, we recommend using within 6 months for optimal accuracy.
2. Can this solution be used with automatic titrators?
Yes, the solution is fully compatible with most automatic titrators. Its consistent viscosity and absence of particulate matter prevent clogging of titration systems while ensuring precise volume delivery.
3. What alternatives exist for non-aqueous titrations if ethanol is unsuitable?
For applications where ethanol interferes, consider KOH solutions in isopropanol or methanol as alternatives. These maintain similar alkalinity properties while offering different solubility profiles for specific analytes.
4. How should this solution be stored to maintain its certified concentration?
Store the tightly sealed container at 15-25°C away from direct sunlight and moisture. The ethanol base minimizes CO₂ absorption, but keeping the container closed when not in use prevents concentration changes.
5. Does this solution require standardization before use?
While the solution is pre-standardized to 0.1N, we recommend periodic verification using primary standard acids like potassium hydrogen phthalate, especially for critical applications or after prolonged storage.
