Product Overview
Silicic acid, n-hydrate, powder from the BAKER ANALYZED™ reagent line is a high-purity silica source designed for demanding laboratory applications. This amorphous, fine white powder offers excellent adsorption properties, making it a preferred choice for chromatographic separations, silica gel preparation, and other analytical processes requiring consistent particle size and purity. The reagent-grade classification ensures minimal impurities, providing reliable and reproducible results in sensitive procedures. Its hydrated form enhances solubility in alkaline solutions while maintaining stability under standard lab conditions. The powder’s uniform texture allows for easy handling and precise dosing, reducing waste and improving workflow efficiency. Whether used as a stationary phase in column chromatography or as a raw material for synthesizing specialized silica products, this silicic acid delivers exceptional performance. The BAKER ANALYZED™ certification guarantees strict quality control, with each batch tested for heavy metals, chloride, sulfate, and other common contaminants. This product is particularly valued in research settings where trace impurities could compromise experimental outcomes. The 500g packaging provides an optimal balance between bulk efficiency and freshness preservation, with a resealable container that protects against moisture absorption during storage.
FAQs
1. What is the particle size range of this silicic acid powder?
The powder typically falls within the 5-40 micron range, though exact particle distribution may vary slightly between batches. For applications requiring specific particle sizes, additional sieving may be necessary.
2. Can this product be used for thin-layer chromatography?
While primarily designed for column chromatography, the fine particle size makes it suitable for TLC when properly prepared with an appropriate binder. The adsorption properties remain consistent across applications.
3. How does this compare to silica gel for chromatography?
This silicic acid powder serves as the raw material for silica gel production. Unlike pre-activated silica gel, it requires additional processing but offers greater flexibility in creating custom stationary phases with specific pore sizes.
4. What is the recommended storage method to prevent clumping?
Store in the original container with the lid tightly sealed at room temperature. For extended storage, consider adding a desiccant packet to the container to absorb any ambient moisture.
5. Does this product contain any crystalline silica?
The amorphous nature of this silicic acid means it contains negligible crystalline silica content, making it safer for handling compared to crystalline forms while maintaining similar chemical properties.
