Product Overview & Quality

Product Name: Sodium thiosulfate solution 0.1N
Brand: Kemaus (Product Code: KA-638)
Grade: Volumetric Standard Solution / Analytical Grade. Prepared and standardized under Kemaus strict laboratory quality control systems to ensure exact normative precision of 0.1 Normal. This ready-to-use matrix eliminates intensive formulation steps, completely removing manual weight or titration variance errors, and provides quick, accurate baselines for operational workflows.
Physical Properties: Odorless, clear, colorless liquid.
Key Use: Heavily utilized as a primary standard titrant solution in analytical chemistry, specifically for redox systems involving iodometric titrations (Iodometry). Commonly applied to determine free residual chlorine in water, evaluate dissolved oxygen (DO) content via the standard Winkler process, and assess iodine value metrics in food, oil, and lipid quality control assays. Also functions as an effective chemical quenching agent to neutralize active oxidizers or residual halogens in microbiological sampling setups.

Safety & Hazards

Classification: Not classified as a hazardous substance according to GHS regulations due to its stable, dilute aqueous profile. It features exceptional chemical safety and low systemic toxicity.
Health Risks: Direct eye contact triggers temporary minor mechanical irritation, watering, or short-term redness. It is benign and non-irritating to intact dermal tissues under normal laboratory handling conditions. Ingestion of very large quantities may cause minor gastrointestinal discomfort.
First Aid Measures: Flush affected eyes or skin immediately with plenty of flowing water. Seek medical advice if irritation develops or persists.

Handling & Storage

Storage: Light and Microbially Sensitive. Extended exposure to direct environmental sunlight or airborne biological contamination can steadily degrade the chemical balance and alter the specified 0.1N normality tier over time. Must be stored in its original, tightly sealed Kemaus container. Keep in a cool, strictly dry, and dark dedicated chemical storage space at stable room temperature (below 30 degrees Celsius).
Precautions: Wear standard personal protective equipment (PPE), including laboratory chemical gloves and safety glasses. Ensure all analytical pipettes and volumetric glassware are thoroughly cleaned before extraction to avoid cross-contaminating the main stock container.
