• Micro-osmomètre


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 down time.

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