Description

PC series sets with the same composition and use as PharmaCount 3M: ready-to-use monodisperse microsphere suspensions at 3,000 particles/mL to check channel thresholds and count precision of liquid optical counters. Only the packaging differs: three bottles of suspension and three of blank, 25 mL each, so each test has its own background control. Polystyrene cross-linked with divinylbenzene, diameters traceable to SI and NIST.

Applications

  • Checking channel thresholds and count precision of liquid optical counters
  • Routine checks with a blank paired with each suspension

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.
