Product Overview
This 0.2N sodium thiosulfate volumetric solution is a high-precision reagent formulated under strict quality controls to meet AVS TITRINORM® standards, ensuring reliable and reproducible results in quantitative analyses. The aqueous solution is stabilized to prevent oxidation and degradation, maintaining its titer strength over extended storage periods. Its standardized normality (0.2N) eliminates the need for time-consuming preparation or standardization procedures, making it ideal for laboratories requiring immediate, accurate titration workflows. The solution’s clarity and homogeneity are optimized to minimize measurement errors, while its compatibility with standard glassware and automated titration systems enhances operational efficiency. Packaged in a 1 L format, it reduces frequent replenishment needs while maintaining solution integrity through airtight, light-resistant containers. The AVS TITRINORM® certification guarantees traceability and compliance with international analytical standards, providing confidence in critical applications where precision is non-negotiable. Its neutral pH and low impurity profile further ensure interference-free reactions, particularly in sensitive redox environments.
FAQs
1
What is the shelf life of this 0.2N sodium thiosulfate solution when stored properly?
The solution remains stable for 12 months from the date of manufacture when stored in its original sealed container at 15–25°C, protected from light and moisture. Regular titer checks are recommended after opening to confirm concentration. 2
Can this solution be used directly for iodometric titrations without further dilution?
Yes, the 0.2N concentration is pre-standardized for direct use in iodometric titrations, including chlorine content analysis and redox reactions, without requiring additional dilution or adjustment. 3
Is this solution compatible with automatic titrators?
The solution is fully compatible with most automatic titrators, provided the system is calibrated for 0.2N sodium thiosulfate and the dispensing components are resistant to aqueous solutions. 4
What precautions should be taken to prevent solution degradation?
Store the bottle tightly sealed in a cool, dark place and avoid exposure to air or metal contaminants, as oxygen and trace metals can accelerate decomposition. Use a dedicated pipette to prevent cross-contamination. 5
How does the AVS TITRINORM® grade differ from standard laboratory-grade sodium thiosulfate?
AVS TITRINORM® solutions undergo rigorous quality testing for normality accuracy, impurity limits, and batch-to-batch consistency, with certified traceability to NIST standards, unlike generic laboratory grades which may require in-house standardization.
