CAS 9003-53-6 — Jeu de comptage de particules (2 blancs (28 mL chacun) et 2 suspensions (25 mL chacune) – USP CRS)

The Particle Count Set (USP CRS) is a standardized reference material used for calibrating and validating particle counting instruments in pharmaceutical manufacturing and quality control. It consists of two empty blanks and two suspensions of known particle concentrations to ensure accurate measurement of particulate contamination in injectable drugs and other sterile products. This set complies with USP standards for particle counting, with each blank and suspension meeting USP <788> and <789> specifications. The blanks are 28 mL glass vials, and the suspensions are 25 mL aqueous solutions containing non-viable particles of defined size and quantity. No signal word applies, and it is stored at ambient conditions. Molekula supplies this Particle Count Set from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
