Advanced® Model 3250 Single-Sample Osmometer

Advanced® Model 3250 Single-Sample Osmometer

Advanced Instruments Osmometer, Model 3250, for Osmolality Measurement

The Advanced Instruments Model 3250 Micro Osmometer determines the osmolality of solutions using freezing point depression (FPD). Ideal for serum, urine or other bodily fluids in clinical applications; and media or formulations in pharmaceutical, biotech or industrial applications.

Automated, single sample, designed to process a 200-250 mL sample, and two-minute test time. The Model 3250 provides the best accuracy and precision in the market today.

  • 0 to 4000 mOsm/kg H2O measurement range offers ideal versatility
  • 200-250 mL provides the greatest precision in a variety of applications.
  • Multi-language operation
  • Unparalleled ease of use
  • Internal diagnostics
  • On-board statistical analysis
  • Results recall up to the last 30 tests
  • Automated calibration
  • On-board printer
  • Hot-Line® Technical Service available 24/7

Advanced Instruments also supplies ControLine Products

  • ClinitrolTM 290 mOsmol Reference Solution<
  • Protinol® Protein-based Controls
  • RenolTM Urine Osmolality Contols
  • Linearity Osmolality Controls

Method – Freezing Point Depression Osmometry
Osmometry measures the total molar concentration of dissolved solids in any solution. The freezing point of a solution is depressed in direct relation to the amount of solute in solution. Click here for a more detailed explanation.

Uses and Applications – Emergency Medicine, Internal Medicine/Endocrinology, Urology/Renal Function, Surgery/Critical Care, Obstetrics/Gynecology, Pharmacy, General Quality Control. Click here for a more detailed explanation.
