Labratory Refractometers

Refractometers are an excellent tool designed to measure a sample’s refractive index and offer suitability for various applications. Lab refractometers are available in multiple sizes, including benchtops, digital refractometers, and handheld refractometers for convenient movement around the lab. Refractometers are designed to measure a sample’s refractive index or polarization of light to help achieve clear and accurate results and can provide transparent liquid or solid substances. It is commonly used to identify a material by determining its purity. Quality control refractometers are created for different scales for specific purposes. Brix scales are perfect for measuring the sugar content of maple syrup, jam, honey, and plenty more and can be calibrated to measure glucose, fructose, and other sugars.

What does a refractometer tell you about a urine sample?

A refractometer measures the specific gravity of a urine sample, which provides information about the urine's concentration. Specific gravity indicates the amount of dissolved substances relative to water, such as salts and waste products. This measurement helps assess the kidney's ability to concentrate or dilute urine, which is critical for diagnosing conditions like dehydration, kidney dysfunction, or urinary tract issues.
