Definition: Specific gravity is the ratio of the weight of a liquid, to that of an equal volume of water at the same temperature and barometric pressure.
Specific gravity is commonly used in industry as a simple means of obtaining information about the concentration of solutions, and when using weight to control volume. A specific gravity of greater than 1 means the solution is heavier than water, and conversely a specific gravity of less than 1 means the solution is lighter than water. A solution with and specific gravity of 1.0234 would mean that 100mL of the solution would weigh 102.34gms.
DYNALABS employs digital density meter technology for testing specific gravity. Test protocols are developed in accordance to USP <841> Specific Gravity. Samples are assayed in triplicate and results are reported to 4 decimal places.
