Product Overview & Quality

Product Name: Sodium sulfate anhydrous
Brand: Kemaus (Product Code: KA-503)
Grade: Analytical Reagent (AR Grade) with premium purity of 99 percent or higher. Manufactured under strict Kemaus laboratory standards, ensuring an entirely moisture-free matrix with ultra-low trace background contaminants to maximize its chemical drying performance.
Physical Properties: Odorless, fine white powder or crystalline granules with a bitter-salty taste.
Solubility: Highly soluble in water; insoluble in most organic solvents.
Key Use: Widely utilized as a primary drying agent (desiccant) in organic chemistry laboratories to remove residual traces of water from organic extracts and solvent phases post-extraction. Also used as a high-purity reagent for formulating laboratory buffer solutions and preparing environmental analytical samples.

Safety & Hazards

Classification: Not classified as a hazardous substance according to GHS regulations. Acts as a mild physical and mechanical dust irritant.
Health Risks: Direct eye contact with fine dust may cause temporary mechanical irritation, watering, or redness. Inhalation of large amounts of dust may cause minor coughing, sneezing, or nasal tract discomfort.
First Aid Measures: Flush eyes immediately with plenty of water for at least 15 minutes. Wash affected skin with soap and water. Seek medical advice if irritation develops or persists.

Handling & Storage

Storage: Highly Hygroscopic. It aggressively absorbs atmospheric moisture, which can cause caking and loss of drying efficacy. Must be stored in the original, tightly sealed Kemaus container in a cool, strictly dry, and well-ventilated space at stable room temperature (below 30 degrees Celsius).
Precautions: Wear standard personal protective equipment (PPE), including laboratory gloves, safety glasses, and a particulate dust mask. Ensure the container is capped tightly immediately after each use to protect its anhydrous properties.
