Product Overview
This sodium thiosulfate volumetric solution is standardized at 0.01 mol/L (0.01 N) concentration, offering exceptional accuracy for redox titrations in analytical laboratories. Formulated under NORMADOSE® quality control, it ensures consistent molar concentration with minimal variability, making it ideal for precise iodine titrations and other redox-based analyses. The solution is stabilized to prevent oxidation, maintaining its potency over extended storage periods when kept under recommended conditions. Its clear, colorless appearance allows for easy visual endpoint detection during titrations, while the pre-diluted format eliminates the need for manual preparation, reducing procedural errors. The solution is compatible with standard glassware and automatic titrators, providing seamless integration into existing lab workflows. Each batch undergoes rigorous testing to confirm its normality, with certification documentation available for traceability. The 60 ml pack size offers sufficient volume for multiple titrations while minimizing waste, making it cost-effective for routine laboratory applications.
FAQs
1. What is the shelf life of this sodium thiosulfate solution when unopened?
The unopened solution maintains its specified normality for 12 months from the date of manufacture when stored at 15-25°C in its original packaging, protected from light.
2. Can this solution be used with automatic titrators?
Yes, the solution is fully compatible with most automatic titrators, though you may need to adjust the electrode calibration settings for optimal performance with your specific instrument.
3. How does the NORMADOSE® standardization differ from regular volumetric solutions?
NORMADOSE® solutions undergo additional quality control measures including multi-point verification of concentration and stricter tolerance limits, resulting in ±0.5% accuracy compared to typical ±1% standards.
4. What precautions should be taken during storage to maintain accuracy?
Store the bottle tightly sealed in a cool, dark place (preferably below 25°C) and avoid exposure to air which can lead to oxidation. Use the original container to prevent contamination.
5. Is this solution suitable for micro-scale titrations?
While primarily designed for standard titrations, the solution can be used for micro-scale work by employing precision microburettes, though you may need to account for minor surface tension effects at very small volumes.
