4D Series Microsphere Size Standards

1.00

Calibrate airborne optical particle counters (OPC) to comply with ISO 21501-4 regulations with the Thermo Scientific™ 4D Series Dry Microsphere Size Standards. Ideal for instrument manufacturers, as well as QA/QC managers in pharmaceutical, biotech and electronics manufacturing, these microsphere reference beads feature a calibration uncertainty—the range of values within which the actual mean diameter will lie—that is less than or equal to 2.5% of the mean diameter. 4D Series are available in 4 different nominal sizes: 3, 5, 7 and 10µm.

Description

(NIST) traceable particle size standards enable laboratories to validate or calibrate their particle sizing instruments or methods in order to comply with ISO, GMP, GLP and other international standards. They are traceable to certified reference materials from international standard organisations through an unbroken chain of measurement leading back to the standard meter.

The ISO 21501-4 standard describes a calibration method designed to improve the repeatability and reproducibility of airborne particle counters. It deals comprehensively with statistical uncertainty and defines limits to a set of performance parameters which must be covered in routine periodic calibration. Conformance to ISO 221501-4 ensures that air particle counter instruments size particles correctly to an acceptable uncertainty level and count particle accuracy to a defined counting efficiency level.
The 4D series Particle Count Standards meets ISO 21501-4.
