how is specific gravity measure with refractometer|how does the refractometer work : wholesalers A urine specific gravity test compares the density of urine and water. It can help doctors diagnose a variety of conditions, including dehydration. When inoculating from glycerol stocks, do not thaw up the whole tube. Keep the tube on ice and withdraw sample with a sterile inoculation loop only from the top part of the frozen solution.

Cl inical refractometers are common in-house screening tools for measuring urine specific gravity (USG) with a minute volume of urine. 1 Veterinarians use USG to determine the concentrating ability of the kidneys, pinpoint the anatomic location of any abnormalities, and assess hydration status. 1-3 This article describes how refractometers work . A urine specific gravity test compares the density of urine and water. It can help doctors diagnose a variety of conditions, including dehydration.
Specific gravity is typically measured with a refractometer when determining the concentration of a solution. A refractometer is an instrument that uses light and a prism to measure the angle of refraction or bending of light when it passes through a sample. This angle of refraction is then used to measure the concentration of a solution.Measuring urine specific gravity is a non-invasive and relatively simple method to evaluate fluid status and guide interventions to maintain optimal hydration levels. It has been shown to be the most valid and reliable method for determining moderate changes in fluid balance. Clinical refractometers have a readout that gives serum albumen and urine specific gravity, which can be used to test for urine sample tampering. Using a Handheld Analog Refractometer. To take a measurement with a handheld analog refractometer, follow these steps and read the manufacturer's instructions:
The refractive index of urine correlates closely with the specific gravity. It is a ratio of the velocity of light in air to the velocity of light in solution, and is directly proportional to the number of dissolved solids in urine.

Alternatively, the specific gravity of a liquid can be determined using a pycnometer, which is a glass container with a specified volume and a special stopper that allows the container to be filled completely and the gas bubbles to escape. A refractometer is an optical device that, like a hydrometer, measures the specific gravity of your beer or wort. It does so by sampling a small amount of liquid, and looking at its optically. The main advantage over a hydrometer is the small sample size needed – . Refractometer is an optical device that can be used to measure the refractive index of a substance (usually fluid) and, by converting the refractive index, one can get the specific gravity, sugar content (Brix, or Plato).

To my knowledge and experience it's enough to autoclave or UV sterilise for DNAse denauration. But for RNAse denaturation autoclaving is not enough.
