The Advanced Instruments Model 2020 Micro 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. The Model 2020 can process up to 20 samples at one time.

Automated, multi-sample, designed to process a 20uL sample with a 90-second test time. The Model 2020 provides maximum productivity, accuracy and reliability.

• Up to 20 samples at one time
• 20 uL sample size is ideal for applications where the sample quantity is limited.
• Stat sample capability
• Multi-language operation
• On-board statistical analysis
• Results recall up to the last 200 tests
• On-board printer
• Connects easily to external barcode scanner
• Internal diagnostics
• Ergonomic, compact design
• Automated calibration
• 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.

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