Count Precision Standards 3000/ml

Count Precision Size Standards are divided in 3 series: COUNT-CAL Count Precision Size Standards / Validex Count Precision Standards / PHARM-TROL Count Precision Size StandardsCOUNT-CAL Count Precision Size Standards is to minimize contamination by eliminating the need for serial dilutions and extensive sample handling. With counts of 3000 particles per mL
COUNT-CAL is a cost-effective
convenient and ready-to-use product for validating liquid particle counters. They are packaged in single-use bottles in an ultraclean diluent and intended to be sampled directly from the bottle. COUNT-CAL was developed for manufacturers of parenteral drugs and ophthalmic solutions.CC10 and CC25 are particularly useful for interim verification for USP 788 and 789 (Particulate Matter in Injections and Particulate Matter in Ophthalmic Solutions) compliance. Concentrations are optimized for light obscuration particle counters and for other low counting applications. Mostly pharmaceutical applications and partly for matching the pharmacopiea USP.Validex Count Precision Size Standards have 1000 particles per mL
the lowest count per mL in the count controls product line. This makes the Validex ideally suited for validating the performance of liquid particle counters at low counting levels. Excellent for instrument calibration and monitoring in the the drinking water industry. These standards contain NIST-traceable polymer particles suspended in ultrapure water at optimal concentrations for single particle light obscuration instruments. Validex Count Precision Size Standards also meet the regulations of the Japanese and Korean Pharmacopeia
so suitable for use in the pharmaceutical industry as well.PHARM-TROL Count Precision Size Standards is for monitoring the precision and reproducibility of liquid particle counter instruments by keeping a continuous record of its performance. They are ready-to-use precision standards designed for regular use in liquid particle counters for USP and verification. Data are generated for internal or customer audits by using these NIST-traceable microsphere suspensions with a known concentration.PHARM-TROL Particle Count Control is ideal for parenteral drug manufacturers seeking interim verification of USP Particulate Matter in Injections
Light Obscuration Particle Count Test. PHARM-TROL is prepared with the same exacting procedures as the USP Count Reference Standard. The product is a 15µm polystyrene microsphere suspension
packaged at 3800 particles per mL of NIST traceable microspheres in 25mL single-use quantities. It is supplied in 6 or 20 bottle sets.The product was developed to provide process control data for particle counting consistency and verification of size calibration. The ready-to-use precision standard is designed for regular use in liquid particle counte
