  COUNT-CAL Count Precision Standards


COUNT-CAL™ is a cost effective and convenient product for validating liquid particle counters.  Packaged in single-use bottles and intended to be sampled directly from the bottle, it eliminates the need for serial dilutions and extensive sample handling, thereby minimizing contamination.  It was developed for manufactures of parenteral drugs and ophthalmic solutions seeking interim verification of USP <788> and <789> (Particulate Matter in Injections and Particulate Matter in Ophthalmic Solutions).

   Product Detail


COUNT-CAL is a ready to use precision standard designed for regular use in liquid particle counters to verify instrument calibration before each use.  This assures the reproducibility of the particle counter by permitting a continuous record of its performance using a NIST traceable microsphere suspension with a precise concentration.

To be used in liquid particle counting and sizing calibration.  Product can assist in USP <788> and <789> interim verification.

The particles are suspended in an ultra clean diluent.  The concentration is optimized for use in light obscuration particle counters and other low concentration counting applications.  The particle diameters are traceable to the Standard Meter through the National Institute of Standards and Technology (NIST).

CC10 and CC25 are ideal for USP <788> and <789> interim testing.  See the PHARM-TROL™ product page for the proper 15 µm count precision standard.
