The SUR-NE Clinical Refractometer from Atago: an essential tool for reliable and instant diagnoses
Designed to meet the needs of healthcare professionals, the SUR-NE clinical refractometer from Atago is a high-precision optical device that allows for quick and reliable assessment of several biological parameters. It combines three essential measurement scales: specific gravity of urine, serum protein concentration, and refractive index. This refractometer stands out for its ease of use, portability, and accurate and reproducible results, making it ideal for hospitals, clinical laboratories, and medical practices.
Its technology is based on the correlation between the concentration of a solution and its refractive index, a fundamental principle used in many diagnostic tests. Measuring the refractive index of serum or plasma allows for an accurate estimation of protein concentration, while urine density is assessed using a method similar to that of a hydrometer. The integrated serum protein scale was developed following clinical analyses of more than 1,400 cases, ensuring a high level of reliability based on robust empirical data.
The device is calibrated dailyusing distilled water to maintain the accuracy of its readings. It has a simple adjustment system via a scale adjustment screw. Thanks to its ergonomic design and low weight, the SUR-NE can be easily handled with one hand, making it a practical tool for rapid interventions. Its observation lens, high-quality optical glass prism and daylight plate ensure optimal reading comfort even in variable lighting conditions.
The SUR-NE is particularly recommended for analysing common clinical solutions such as urine, serum and specific biological fluids. It is also suitable for demanding environments thanks to its robust housing, resistance to moderate shocks and tolerance to storage temperature fluctuations (0 to 40°C). In addition, maintenance is simplified by the ease with which the prism can be cleaned with a soft cloth and water. When analysing oily substances or substances containing residues, it is recommended to clean the prism with ethyl alcohol.
The SUR-NE refractometer offers a winning combination of cutting-edge technology and ease of use. It represents a sound investment for healthcare professionals looking for a reliable device for clinical diagnosis, while ensuring easy handling and consistent accuracy. With its triple scale, the SUR-NE condenses essential features for common medical analyses into a single portable instrument, while guaranteeing analytical rigour worthy of the most demanding laboratories.
