When practical, affirm accuracy of measurements by weighing a volume with the calculated fluid, then calculating that quantity by dividing the load from the exact price of the density, or precise gravity, on the measured fluid. Suitable density or certain gravity values programmed in automated compounding products, which measure by fat utilizing the quotient with the programmed quantity divided because of the density or specific gravity, need to be confirmed to become precise ahead of and right after providing volumes from the liquids assigned to each channel or port.

Failures are indicated by visible turbidity (cloudiness) or "strings" or "clumps" in normally very clear media in almost any of the media-fill models on or just before 14 days.
