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 μL 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 μL provides the greatest precision in a variety of applications.

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.

 

Uses and Applications – Emergency Medicine, Internal Medicine/Endocrinology, Urology/Renal Function, Surgery/Critical Care, Obstetrics/Gynecology, Pharmacy, General Quality Control.
