Description
PharmaCount 3M set: six 25 mL bottles of the same ready-to-use monodisperse microsphere suspension at 3,000 particles/mL, to set or check channel thresholds and count precision of liquid optical particle counters, with no dilution. The microspheres are polystyrene cross-linked with divinylbenzene (refractive index 1.59 at 589 nm, density 1.05 g/cm³), in an aqueous medium with dispersing agents that prevent clumping and adhesion to flow surfaces. Certified diameters are traceable to SI, including NIST, and every bottle has its own magnetic stir bar for direct sampling.
Applications
- Setting and checking channel thresholds of liquid optical particle counters
- Count precision verification
- Routine checks in contamination control laboratories

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.
How do I see the prices?
List prices per pack, excluding VAT, are shown after signing in to the customer area. With the quote request we confirm price, availability and delivery time.
