Fiske® 210 Micro-Sample Osmometer

When you need precise, rapid results from an extremely small sample, the only answer is the Fiske® 210 Micro-Sample Osmometer.
The Fiske 210 continues our 50-year commitment to osmometry - a commitment that is well known to thousands of users around the world.

The Fiske® 210 freezing-point osmometer requires only a 20µL sample size, which provides accurate osmolality results in less than 90 seconds. For convenience, the fully accessible probe design is easy to clean and service. The Fiske 210 is not only your most reliable option, it’s the easiest to use. Just pipet 20µL of sample into a disposable sample tube, then place the tube into the test chamber. Lower the probe into the sample and push the “Test” button. Results are displayed in ninety seconds.

Microprocessor control ensures repeatability and accuracy. The Fiske 210 calibrates automatically at the push of a button, with no user adjustments. Because calibration is highly stable, however, the procedure is seldom required. Self-diagnostics alert the operator to any malfunctions or abnormal test conditions through messages on the display.

Since the Fiske 210 Osmometer doesn't use a liquid cooling bath, you'll have minimal routine maintenance. In fact, you don't have to worry about preventive maintenance, either. All these features save you costly operator labor and downtime.


  1. Determine Osmol Gap – actual versus calculated osmolality is a rapid indicator for toxicology and trauma cases. Remember, only the freezing- point method is sensitive to alcohol and ketones.
  2. Hydration Status for Athletes – weight class and endurance events are conducive to dehydration, with performance and health consequences.
  3. Mannitol Treatment – maintain, without exceeding, critical level of therapeutic infusion.
  4. Glycine Ingestion – monitor the absorption of irrigation fluids in surgical procedures.
  5. Renal Function – evaluate concentrating ability and monitor ADH therapy.
  6. Differentiate DKA and NKH – only a measured osmolality can make this determination and guide effective therapy.
  7. Sample Authentication for Drug Screens – low urine osmolality is indicative of tampering.


  1. Automatic calibration
  2. Alphanumeric display - Results, user prompts, and instrument diagnostics are clearly displayed.
  3. No fine-tuning or user adjustments during calibration. The instrument’s microprocessor automatically makes calibration adjustments at the push of a button.
  4. Easy push-button operation - Requires minimum operator training.
  5. Smallest sample size -  Only 20 microliters of sample needed.
  6. Printer, RS232C and barcode scanner ports - A full range of data handling options are available. Unit connects easily to printer, computer, and scanner.
  7. Solid-state cooling - The 210 has no liquid cooling bath; no maintenance required.
