Product Overview
This 1 mol/L (1N) potassium hydroxide (KOH) volumetric solution is a high-purity, pre-standardized reagent designed for precise analytical applications. Formulated under stringent quality controls, it adheres to AVS TITRINORM® standards, ensuring minimal carbonate contamination and exceptional batch-to-batch consistency. The solution is stabilized to prevent absorption of atmospheric CO₂, maintaining its molarity over extended storage periods. Its clarity and homogeneity eliminate the need for filtration or additional standardization, saving valuable lab time. The aqueous formulation is optimized for compatibility with automatic titrators and manual burettes, reducing systematic errors in volumetric analysis. Packaged in a high-density polyethylene (HDPE) bottle with a tamper-evident seal, it guarantees integrity during transport and storage. Ideal for laboratories requiring traceable, ready-to-use reagents, this KOH solution meets the demands of pharmacopeial assays, environmental testing, and industrial quality control where accurate alkalimetric determinations are critical. The absence of preservatives ensures interference-free results in sensitive applications, while the certified concentration simplifies compliance with GLP/GMP documentation requirements.
FAQs
1. Is this KOH solution carbonate-free, and how is this verified?
The solution undergoes rigorous testing to ensure carbonate levels remain below 0.2%, verified through acid-base titration against a primary standard. The AVS TITRINORM® certification includes this parameter in its quality assurance protocol.
2. Can this 1N KOH solution be used with non-aqueous titrations?
While primarily designed for aqueous titrations, it can be employed in non-aqueous systems if the solvent is miscible with water. However, you may need to re-standardize the solution in such cases, as solvent polarity can affect the effective concentration.
3. What is the shelf life of this volumetric solution after opening?
When stored in its original HDPE bottle with the cap tightly sealed, the solution remains stable for 12 months after opening. Use a CO₂-absorbing trap in the bottle neck to extend stability further, especially in high-humidity environments.
4. How does this compare to solid KOH pellets for preparing solutions?
This pre-standardized liquid eliminates the risks of incomplete dissolution, hygroscopicity-related weight errors, and carbonate formation that occur when preparing solutions from solid KOH. It also saves time by removing the need for standardization procedures.
5. Are there any compatibility issues with specific titrator models?
The solution is compatible with most automatic titrators, including Metrohm, Mettler Toledo, and Hach systems. For models with sensitive electrodes, rinse the dosing system with deionized water before use to prevent potassium ion carryover.
