Fisherbrand Handheld Analog Clinical Refractometer #12-561-340

Features

• Refractometers have been used for measuring the concentration of solutions for more than a century. Their primary purpose is to measure the degree at which light bends as it passes through a medium, and is used in a wide range of applications and industries as a quality control and diagnostic tool.
• Fisherbrand Analog Refractometers are designed for simple operation and built with an all-metal construction for durability. Its industrial design is the most commonly used design among refractometer manufactures as it is a cost-effective model to build.
• Each unit is inspected in the United States by a factory qualified technician under a rigid quality control process to ensure its accuracy, and performance.



Key Features:



• Quickly calibrate the instrument with a turn of a screw, and distilled water
• Comfortable eyecup blocks out ambient light and allows for crystal clear viewing of readings
• Automatic temperature compensation prevents the need for constant re-calibration of the instrument. As the ambient temperature changes, the scale will automatically compensate for the difference in the degree of refraction. This ensures an accurate reading every time
• All metal construction creates durability. NOTE: Model 12-561-340 comes without ATC
• Footrest allows the instrument to be set on a flat surface without the worry of it rolling off working surfaces
• Rubber hand grip is comfortable, easy to grasp. Its non-slip pattern grip reduces that chance of accidentally dropping the instrument
• Double hinged daylight plates create two points of movement to allow for greater flexibility in movement; making it easy to add samples and clean
• Portable, easy to use design.



Clinical Models:



• Quickly and accurately get an indication of basic health parameters such as dehydration and blood plasma protein levels. Fisherbrand Analog Clinical Refractometers use three-scales to measure Total Serum Protein, Urine Specific Gravity, and Refractive Index. They are ideal for use in quality control, research, and clinical laboratories.
• Urine Specific Gravity: 1.000ppt to 1.050ppt with granularity to measure down to 0.001ppt at a 0.002ppt degree of accuracy
• Serum Protein: 1g to 12g with granularity to measure down to 0.2g/100mL at a 0.2g/100mL degree of accuracy
• Refractive Index: 1.334nD to 1.360nD with granularity to measure down to .0005nD at a 0.0005nD degree of accuracy.
