EZY-CAL Count and Size
Standards
A series of ready to use, certified standards
for validating particle counters with an absolute
minimum of dilution or handling. They are suspensions
of polymer microspheres in water with a concentration
of 2000 particles per mL. A magnetic stir-bar
is enclosed in each 100mL bottle for clean, convenient
and direct sampling.
EZY-CAL standards consist of polymer microspheres
with a density of 1.05 g/cm3 and refractive index
of 1.59 at 540nm. Mean diameters from 2 to 70µm
are available, all with narrow size distributions.
The aqueous medium contains dispersing agents
to keep particles from flocculating or adhering
to surfaces within the instrument system.

COUNT-CAL
Count Precision Standards
A
cost-effective and convenient range of products
for validating particle counter developed for
manufacturers of parenteral drugs and ophthalmic
solutions seeking interim verification to USP
<788> and <789>.
Available
in mean sizes from 2 to 70 µm, they are
optimised for use with light obscuration particle
counters and other low concentration applications.

Particle
Counter Size Standards
A new series of NIST traceable size standards
for calibration and validation of counters used
for monitoring air- or liquid-borne particle contamination.
They consist of a dilute suspension of polymer
microspheres in low-residue aqueous suspension
and are supplied in dropper-tipped 15mL bottles
and accompanied by a certificate of calibration.
Mean diameters range from 0.1 to 100 microns.

PHARM-TROL
Particle Count Control
PHARM-TROL™ Particle Count Control is a
product containing NIST traceable size standards
with a measured particle count. The product was
developed for manufacturers of parenteral drugs
and ophthalmic solutions seeking interim verification
of USP <788> and <789> (Particulate
Matter in Injections and Particulate Matter in
Ophthalmic Solutions). The particle diameters
are traceable to the standard meter through the
National Institute of Standards and Technology
(NIST).
PHARM-TROL™ is prepared with the same exacting
procedures as the USP Count Reference Standard
and provides process control data for particle
counting consistency and verification of size
calibration.
