    Advanced Instruments 3900 Osmometer

    Advanced Instruments 3900 Osmometer

    Cambridge ID #: 10789

    The Advanced Instruments Model 3900 Multi-Sample Osmometer determines the osmolality of solutions using freezing point depression (FPD). It is ideal for serum, urine or other bodily fluids in clinical applications, and media or formulations in pharmaceutical, biotech or industrial applications.Automated and multi-sample, it is designed to process a 200-300 μL sample, 90 second test time, and approximately 30 samples per hour. The Model 3900 provides the best accuracy and precision in the market today.

     

    • Sample Volume: 0.2 to 0.3 mL (glass or disposable plastic tubes)
    • Low Range: Less than ±0.5% from a straight line between 0 and 1500 mOsm/kg H2O
    • High Range: Less than ±1.0% from a straight line between 1500 and 4000 mOsm/kg H2O
    • Repeatability: 0 to 400 mOsm: ±2 mOsm/kg H2O (1 S.D.)  400 to 4000 mOsm: ±0.5% (1 S.D.)
    • Drift: Less than 1 mOsm/kg H2O per month
    • Test Time: 90 seconds per sample (typical)
    • Sample throughput: 30 samples per hour at 23ͦ C (73 ͦ C); less in higher ambient  temperature and in high range
