Product Overview

Sodium sulfate anhydrous AnalaR NORMAPUR® is a high-purity, ACS-grade reagent designed for critical laboratory applications where precision and consistency are paramount. This analytical-grade sodium sulfate meets the stringent standards of the American Chemical Society (ACS) and European Pharmacopoeia (Ph. Eur.), ensuring exceptional quality for demanding procedures. Its anhydrous form eliminates moisture interference, making it ideal for use as a drying agent in organic solvent purification and other moisture-sensitive reactions. The fine, free-flowing powder dissolves readily in water, providing a reliable source of sulfate ions without introducing impurities. Manufactured under strict quality controls, this reagent delivers consistent performance batch after batch, reducing variability in experimental results. The NORMAPUR® designation indicates it has undergone rigorous testing for trace metal impurities and other contaminants, meeting the exacting requirements of modern analytical laboratories. Its neutral pH and stable chemical properties make it suitable for a wide range of applications where chemical inertness is required. The 500g packaging provides an optimal balance between bulk efficiency and freshness preservation, with a resealable container that maintains product integrity during storage.

FAQs

1. What is the difference between anhydrous and hydrated sodium sulfate?

Anhydrous sodium sulfate contains no water molecules in its crystal structure, while the hydrated form (typically decahydrate) includes water of crystallization. The anhydrous form is preferred for drying applications as it can absorb moisture from solvents without introducing additional water.

2. How should I store this reagent to maintain its quality?

Store in a tightly sealed container in a cool, dry place away from direct sunlight. Keep the container properly closed when not in use to prevent absorption of atmospheric moisture, which could affect its anhydrous properties.

3. Is this product compatible with all organic solvents?

While sodium sulfate is generally compatible with most organic solvents, it’s recommended to verify compatibility for specific applications. It’s particularly effective with solvents like diethyl ether, hexane, and toluene where it serves as an excellent drying agent.

4. What quality certifications does this product have?

This sodium sulfate meets both ACS reagent grade specifications and European Pharmacopoeia (Ph. Eur.) standards. The AnalaR NORMAPUR® designation indicates it has passed additional purity tests for analytical applications.

5. Can this be used for food or pharmaceutical applications?

While this product meets Ph. Eur. standards, it’s primarily intended for laboratory use. For food or pharmaceutical applications, you would need to verify compliance with specific regulatory requirements for those industries.
