Abstract: Disclosed herein are tissue digesters and methods of operation. In some examples, a tissue digester includes a fluid container having an upper region and a lower region; a first drain extending from within the fluid container at the lower region and in selective fluid communication with a first drain conduit; a second drain extending from within the fluid container at the upper region and associated with a second drain conduit; and a divider within the fluid container projecting from an inner sidewall of the fluid container from a first elevation at or beneath that of the second drain to a second elevation above the second drain thereby to form, with the inner sidewall, a trough, wherein fluid within the fluid container is permitted to enter the trough thereby to exit the second drain only when at least a level of the fluid in the fluid container exceeds the second elevation.

Abstract: A sealable body bag is disclosed. The sealable body bag comprises a soluble component configured to be impermeable to body fluids, a leak-resistant sealing component; a permeable insoluble component, and an insoluble identification tag configured to identify the insoluble component.
