Abstract
A system performs a non-destructive measurement of a density gradient to automatically replicate and dispense the density gradient. The system obtains measurements at points along a length of the density gradient and generates a profile of the density gradient based on the measurements. The system uses the profile to replicate the density gradient of components in a second container. The system inserts a distal end of a probe into the second container, and pumps separate components into a manifold and mixing chamber connected to a proximal end of the probe to automatically dispense the density gradient in the second container.
