Product Overview
Calcium carbonate powder from BAKER ANALYZED™ reagent series is a high-purity chemical designed for laboratory applications where precision and consistency are critical. This fine, white powder is chemically inert under normal conditions, making it suitable for use in analytical procedures that require reliable reactivity. The reagent-grade classification ensures minimal impurities, allowing for accurate results in titration, precipitation, and other quantitative analyses. Its uniform particle size distribution enhances solubility and reaction efficiency, while the stable composition prevents variability between batches. The powder form facilitates easy weighing and dispensing, reducing preparation time in lab workflows. Compatible with most standard laboratory equipment, this calcium carbonate variant maintains integrity across a wide pH range, though it decomposes under acidic conditions to release carbon dioxide. The 500 g packaging provides an optimal balance between bulk supply and freshness preservation, with a resealable container that protects against moisture absorption. As a fundamental chemical in many protocols, this product meets the stringent requirements of research environments where trace contaminants could compromise experimental validity.
FAQs
1. What is the particle size range of this calcium carbonate powder?
The powder typically features a fine particle distribution with most particles falling between 1-10 microns, though exact sizing may vary slightly by production batch. This range ensures good dispersibility in aqueous solutions while maintaining flowability for accurate weighing.
2. Can this reagent be used in food or pharmaceutical applications?
While chemically identical to food-grade calcium carbonate, this reagent-grade product is not certified for human consumption or pharmaceutical use. It is specifically processed for laboratory applications where analytical purity takes precedence over regulatory compliance for ingestible products.
3. How should this powder be stored to maintain its purity?
Store the container tightly sealed in a cool, dry environment away from direct sunlight and moisture sources. Exposure to humid conditions may cause partial conversion to calcium bicarbonate or clumping. The original packaging is designed to minimize air exchange when properly closed.
4. What alternatives exist if I need a higher purity grade?
For applications requiring ultra-high purity, consider ACS-grade or primary standard calcium carbonate products. These variants undergo additional purification steps to reduce trace metal contaminants below parts-per-million levels, though they come at a higher cost per gram.
5. Does this product contain any anti-caking agents or additives?
This BAKER ANALYZED™ reagent contains no added anti-caking agents or flow enhancers. The pure calcium carbonate composition is maintained to prevent interference with analytical procedures, though this may result in slightly reduced flowability compared to industrial-grade variants.
