Compounds

This section details the large range of inorganic compounds for R&D and production environments.

Most compounds are supplied in a variety of forms: powders, pieces, tablets, liquids and in a range of purities and sizes.

The purities stated are based on total metallic impurities, unless otherwise stated.

Small R&D quantities are available, along with larger production quantities, enabling Testbourne to work with customers from the beginning of research right through the development stage to full production scale-up.

All materials are supplied with the appropriate Material Safety Data Sheets and Certificate of Analysis, relevant to the lot number supplied. The Certificate of Analysis typically lists metallic impurities only. For non-metallic impurities, please enquire.

PowdersParticle Size Measurement for Powders

Typically three procedures are employed to measure particle size: sieve, Microtrac Laser Diffraction and Fisher Sub-Sieve Sizing.

Almost all particle sizes listed in the section are based on Fisher Sub-Sieve Sizing, however, please bear in mind that the Fisher size must be looked upon only as a general guide to powder fineness and not as a measure of actual particle size distribution.

Should a particle size be expressed as -325 mesh, this powder will pass through a 325 mesh sieve and the particles will be smaller than 325 mesh. If a powder is defined as -200, +325 mesh, the powder will pass through a 200 mesh sieve but will be retained by a 325 mesh. Please note that the material that is less than 200 mesh but greater than 325 mesh in size, may vary in size, depending upon the position of the particle relative to the sieve openings as it passes through.
