Description

Size standards from the NanoStandards and MicroStandards lines whose mean diameter is certified by an independent ISO/IEC 17025 accredited metrology institute, on material from the original lots. Beyond NIST traceability, usually obtained by in-house measurements against SRMs, here the measurement is performed under accreditation: atomic force microscopy (AFM) from 0.1 to 5 µm and laser scanning confocal microscopy (LSCM) from 10 to 30 µm. The certificate is ISO/IEC 17025 compliant and meets the requirements for instrument calibration in an accredited laboratory. 5 mL vials; each code states the certified mean diameter of the lot.

Applications

  • Calibration of particle sizing instruments in ISO/IEC 17025 accredited laboratories
  • Metrological verification of DLS, laser diffraction and optical counters
  • Higher level reference to check working standards

Frequently asked questions

Are the standards traceable?

Yes: mean diameter, standard deviation and uncertainty are traceable to NIST and the International System of Units (SI) and stated on the certificate of every lot. The ISO/IEC 17025 series is certified by an accredited metrology laboratory.

Which control do I need for USP <788>?

For subvisible particle counting in injectables, use the PharmaCount controls: the USP <788> set for routine verification, the 3M and PC sets for single diameters. For USP <729> there is PharmaCount BiCal.

Can I order a diameter I do not see?

Yes: other diameters, concentrations and dyes are available on request. Tell us the value you need and we will send a quote.
