Application:

The OSM-BF3 osmometer is an instrument designed for determining the osmolality of solutions and various body fluids. It is suitable for the osmolality analysis and testing of intravenous injections, intrathecal injections (among other injections), eye drops, blood, urine, etc. Fully complying with the testing standards specified in the 2020 Edition of the Chinese Pharmacopoeia (ChP), United States Pharmacopoeia (USP), and European Pharmacopoeia (EP).

Advantage:

  • Intelligent design with strong anti-interference capability, excellent repeatability, and automatic probe lifting / lowering;
  • User-friendly full-color LCD touch screen with intuitive, easy-to-understand menus and rich interface content;
  • Wide measurement range and minimal sample volume requirement, suitable for osmolality testing of injections, eye drops, biological products, and trace pharmaceuticals;
  • Provision of multiple concentration calibration solutions, supporting two-point and multi-point linear calibration with high linearity and detection accuracy;
  • Built-in names of hundreds of ChP-listed injections for convenient sample information presets.
  • Equipped with a dual semiconductor refrigeration system (no refrigerant needed).
  • It features an anti-deviation cold needle guide design, ensuring pollution-free and noise-free operation.
  • Memory storage for calibrating parameters and 50,000 data sets (standalone, no expansion needed), supporting real-time date/time stamping on test reports;
  • Built-in microprinter for long-term preservation of measurement results;
  • Four-level password-protected permission management, fully meeting the GMP data integrity requirements.
