Osmometry, a measurement of osmolality by the freezing point method, is an important diagnostic method used in a broad range of clinical applications not currently available by any other means.

For example, osmometry is critical in improving patient care by its direct measurement of body fluid osmolality, thus providing clinical information not available by any other means. Clinicians can make more timely diagnoses and institute more appropriate patient care which can translate to decreased health care costs of the institution.

Freezing-point depression osmometry is capable of measuring all osmotically active solutes within the range of 0-4000 mOsmol/kg H2O, including volatile substances, making it the most sensitive and accurate technology available.

Practical Applications for:
• Emergency Medicine
• Internal Medicine/ Endocrinology
• Urology/Renal Care
• Obstetrics/Gynecology
• Pharmacy/Quality Control
