Retentate plate

FIG. 1 is a front view of the retentate plate in a first aspect of the present invention.

FIG. 2 is a rear view thereof.

FIG. 3 is a top view thereof. The bottom view on the opposite side thereof is a mirror image of the top view.

FIG. 4 is a right side view thereof.

FIG. 5 is a left side view thereof.

FIG. 6 is a front upper side perspective view thereof; and,

FIG. 7 is a rear lower side perspective view thereof.

The retentate plate of the present invention allows retentate to be conveniently collected at the end of a single-pass tangential flow filtration (TFF) process. Optional handles allow for ease of set-up of the assembly but can be removed to allow for use in a multilevel assembly where the handles would interfere with the next level. Fluid exiting the assembly is sufficiently concentrated after a single pass through the series of cassettes that retentate recycle is not necessary.

The broken lines in the Figures are for illustrative purposes only, and form no part of the claimed design.
