Assay Silica Flour/Sand 400 Mesh – 8 OZ

Discover the precision of the Assay Silica Flour/Sand 400 Mesh for lab-grade applications. This 40-micron ground silica (flour) sand is inherently bright, white, low in moisture, inert and at least 99.2% Si02, delivering unmatched fineness and a remarkably consistent particle size.

Formulated as silica flour with high purity, this lab-grade silica combines silica flour and silica sand in a uniform 400 mesh that supports precise weighing, mixing and quality control. It is bright, inert and low in moisture, ensuring minimal contamination in analytical workflows.

• Ultra-fine, 40 micron (400 mesh) particle size for consistent dispersion and measurement.
• High purity with at least 99.2% Si02 for reliable analytical results.
• Bright, white appearance minimizes color interference in optical or spectrographic work.
• Low moisture and inert formulation reduces contamination risk and drift.
• Lab-grade silica flour ideal for assays, calibration, and quality control.

With a minimum purity of 99.2% Si02, this assay-grade silica delivers high purity suitable for lab and industrial applications.
