Count-Cal Precision Standards

COUNT-CALCOUNT-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. Polystyrene microspheres are suspended in an ultra clean diluent.
Concentration is optimized for use in light obscuration particle counters and other low concentration counting applications
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 USP 789 interim testing. Storage Conditions: Store between 4° and 30°C. Do not freeze the particle suspension. Store upright and keep bottle tightly sealed to avoid contamination. Throughly disperse per protocol prior to use.
Includes: Certificate of Calibration and Traceability to NIST; Particle counting protocol; Material Safety Data Sheet. Certifications: NIST traceable

Count Precision Standards are easy-to-use liquid particle count controls.
COUNT-CAL* is a cost effective, 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 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).
