Product Overview
This anhydrous magnesium sulfate powder is a BAKER ANALYZED™ reagent-grade desiccant engineered for critical laboratory applications requiring ultra-low moisture content. The ultra-fine, free-flowing particles provide maximum surface area for efficient water absorption, making it ideal for drying organic solvents and preparing moisture-sensitive reactions. With a minimum assay of 99.5% MgSO₄, this reagent meets stringent analytical standards, ensuring consistent performance in quantitative procedures. The anhydrous form eliminates hydration variability, while the powder consistency allows precise weighing and homogeneous mixing. Packaged in a resealable container to maintain purity during storage, this product undergoes rigorous quality control to guarantee batch-to-batch reliability. The reagent’s high solubility in water (35.1 g/100 mL at 20°C) and negligible solubility in organic solvents make it versatile for both aqueous and non-aqueous systems. Each 500g pack provides sufficient quantity for repeated use while maintaining cost-effectiveness for regular laboratory operations.
FAQs
1. What is the typical drying capacity of this anhydrous magnesium sulfate?
This reagent can absorb approximately 33% of its weight in water, though practical capacity depends on exposure conditions and residual moisture in the system being dried.
2. How does this compare to other common laboratory desiccants like silica gel?
Magnesium sulfate offers higher water absorption capacity per gram than silica gel and maintains its powder form when saturated, unlike silica gel which forms clumps when fully hydrated.
3. What is the recommended storage method to maintain anhydrous properties?
Store in the original tightly sealed container with the desiccant cap engaged, in a cool, dry place away from direct sunlight and moisture sources. For extended storage, consider adding a secondary desiccant packet inside the container.
4. Can this be used for drying gases in addition to liquids?
While primarily designed for liquid drying, the powder form can be used in gas drying tubes with proper packing, though specialized gas drying agents may offer better performance for high-flow applications.
5. What is the particle size distribution of this powder grade?
The ultra-fine powder typically passes through a 100-mesh sieve (150 micron), with 90% of particles between 75-150 microns for optimal surface area and handling characteristics.
