Liquid-Borne Particle Counter

Serves for measurement of insoluble particles in injections,for example at pharmaceutical plants.

  • Compliant with insoluble particulate matter testing for injections in accordance with the Japanese Pharmacopeia (JP), United States Pharmacopeia (USP),European Pharmacopeia (EP), Korean Pharmacopeia (KP) and Chinese Pharmacopoeia (ChP).
  • Supports small volume measurement (USP 787). Special small size sample stand available as option, for 10 mL syringes and ampoules etc.
  • Compliant with FDA’s 21 CFR Part 11. Comprehensive operator and password management functions, as well as electronic signature support.
  • Serial communication function allows output of measurement data to a Laboratory Information Management Systems (LIMS) etc.
  • Measurement results can be output as PDF or text file (tab delimited) format.
  • Large 10.4 inch LCD panel provides information in an easy to read format.
  • Integrated SSD storage improves data access speed.
  • Measurable particle size range 1.3 μm to 100 μm, flow rate 25 mL/min (10 mL/min available as factory option),with up to 20 particle size range settings.
  • Light source uses semiconductor laser with three-year guarantee. (under normal use and proper handling)
