Quantity/Pack Size – 500 g
Form – Crystalline powder
Grade – ARS, ACS
Application – Analytical reagent, calibration standards, inorganic synthesis

Product Overview

Sodium fluoride (NaF) in ARS (Analytical Reagent Standard) and ACS (American Chemical Society) grade represents the highest purity available for laboratory applications. This crystalline powder is meticulously processed to ensure a minimum assay of 99.0%, with tightly controlled trace impurities (≤0.005% heavy metals, ≤0.01% insolubles). The ACS certification guarantees compliance with stringent specifications for moisture content, pH stability, and chloride/sulfate residuals, making it indispensable for quantitative analysis. Its hygroscopic nature necessitates careful handling, though the product remains stable under recommended storage conditions. The fine, free-flowing powder dissolves readily in water (42 g/L at 20°C) while exhibiting negligible solubility in organic solvents. Packaged in airtight HDPE containers with tamper-evident seals, this reagent maintains integrity during transit and storage. The product’s low heavy metal content and precise stoichiometry make it particularly valuable for gravimetric analysis and fluoride ion standardization procedures.

FAQs

1. What is the difference between ARS and ACS grades for sodium fluoride?

ARS grade meets Indian analytical reagent standards, while ACS grade follows American Chemical Society specifications. Both ensure high purity but may have slight variations in impurity limits.

2. Can this sodium fluoride be used for fluoride ion selective electrode calibration?

Yes, the high purity and precise fluoride content make it suitable for preparing calibration standards for fluoride ion selective electrodes.

3. What is the typical shelf life of this product?

When stored in the original, unopened container at room temperature, the product maintains its specifications for at least 3 years from the date of manufacture.

4. Is this product compatible with glass containers for long-term storage?

While glass is chemically resistant, we recommend using the original HDPE container as fluoride ions can slowly etch glass surfaces over extended periods.
