Product Overview
Sodium thiosulfate, anhydrous, in granular form is a highly purified BAKER ANALYZED™ reagent designed for critical laboratory applications. This compound is widely recognized for its role in redox titrations, particularly in iodometry, where its precise stoichiometry ensures accurate analytical results. The anhydrous form eliminates moisture-related variability, making it ideal for applications requiring consistent performance. The granules are free-flowing, which enhances ease of handling and minimizes clumping during storage or use. The reagent grade ensures minimal impurities, providing reliable and reproducible results in quantitative analyses. Its stability under standard laboratory conditions further enhances its utility as a primary standard in volumetric analysis. The compound is also effective in neutralizing chlorine, making it valuable in water treatment simulations or related experimental setups. The granular form dissolves rapidly in aqueous solutions, ensuring quick preparation of standardized solutions without residual particulates. This product is manufactured under stringent quality controls to meet the exacting standards of analytical chemistry, ensuring batch-to-batch consistency for long-term research projects.
FAQs
1. What is the shelf life of anhydrous sodium thiosulfate granules?
The shelf life is typically 2-3 years when stored in a tightly sealed container away from moisture and direct sunlight. Always check the label for the exact expiration date.
2. Can this product be used for photographic development?
While sodium thiosulfate is commonly used in photography as a fixer, this reagent-grade product is optimized for laboratory applications rather than photographic processes.
3. How should I store these granules to maintain purity?
Store in an airtight container in a cool, dry place. Exposure to humidity can cause the anhydrous form to absorb moisture, potentially altering its properties.
4. Is this product compatible with standard laboratory glassware?
Yes, it is fully compatible with borosilicate glass and most common laboratory plastics. Avoid prolonged contact with metals to prevent potential corrosion.
5. What alternatives exist if I need a hydrated form?
Sodium thiosulfate pentahydrate is the most common hydrated alternative, though it requires adjustments in calculations due to its water content.
