A tissue processing apparatus, a filter and a method for processing tissue therefrom #! The problem to be solved is to provide a portable apparatus for processing harvested fat to form a good quality graft that does not clog syringes, and the problem is solved by providing an apparatus as in the present invention with a filter that is inclined to the base of the apparatus and comprises of plurality of elongated protrusion that are structured at an angle on the surface of the filter and blocks the fibres when the harvested fat moves on the inclined surface of the filter, thereby filtering the harvested fat and avoiding clogging of syringes.
