![]() Urine specific-gravity measurements normally range from 1.002. A monochromatic light is led to the drop and the specific gravity can be measured depending on the angle of refraction of the light. Urine specific gravity is a measure of the ratio of the density of urine to the density of water. Refractometer: Only a drop of urine is needed.With a calibrated scale the specific gravity can be read depending on how much the test tube float in the distilled water. Urinometer: A test tube is filled with 10 or 20 ml of urine and then is placed in distilled water at 68-72✯ (20-22ªC).Specific gravity may be also measured at labs with other procedures. They comprise up to 10 or more different reagents or chemical pads to perform different urine tests at the same time. In laboratories, there are automated machines that perform the analysis very fast, but it is also possible to buy strips that let you analyze a urine sample at home. Specific Gravity (SG) is the ratio of the density of the substance to a reference density, usually deionized water. It reacts (change color) when it is dipped into the urine specimen. Specific Gravity Bottle with Ground in thermometer range 0 to 50☌,with works Certificate. The dipstick may comprise a reagent or chemical pad. Specific Gravity Bottles chemistry lab instruments, laboratory glassware equipments, Educational Lab instruments, Laboratory Equipment, lab measuring equipments, science equipments supplies. The urine gravity test is measured frequently using reagent strips or dipsticks. This sample will be sent to the lab for the analysis. The patient must collect a sample of the urine in a specific container using a special kit. This test is performed along with other urine tests in what is called a urinalysis.
