Particle Size Standards

Calibration, Validation and Testing

Particle Technology Ltd works closely with the world-leading manufacturer of particle size standards, Thermo Fisher Scientific (formerly Duke Scientific/Duke Standards), and can supply their full range of Certified Particle Size Standard Microspheres.

NIST traceable polymers

Available as highly uniform microspheres in a range of materials, colours and sizes from 20nm to 3000µm – these particle standards can be used by manufacturers and users for calibration, verification and validation of all types of particle sizing systems and instruments, as well as being used extensively in the life sciences, biotechnology and pharmaceutical industries.

Each standard is supplied with a Certificate of Calibration and Traceability. The certificate includes a description of the calibration method, a table of its chemical and physical properties and a Safety Data Sheet which includes handling and disposal instructions.
