Document the reproducibility of a particle counter by permitting a continuous record of its performance. Document the reproducibility of a particle counter by permitting a continuous record of its performance with Thermo Scientificâ„¢ PHARM-TROLâ„¢ Count Precision Size Standards, ready-to-use precision standards designed for regular use in liquid particle counters for USP <788> and <789> verification. Data is documented for internal or customer audits by using a NISTâ„¢-traceable microsphere suspension with a known concentration. Features: Contains NISTâ„¢-traceable size standards with a measured particle count Developed for manufacturers of parenteral drugs and ophthalmic solutions seeking interim verification of USP <788> and <789> verification (Particulate Matter in Injections and Particulate Matter in Opthalmic Solutions) Particle diameters traceable to the Standard Meter through the National Institute of Standards and Technology Prepared with the same exacting procedures as the USP Count Reference Standard, providing process control data for particle counting consistency and verification of size calibration
