A fat harvesting container, having a transparent container assembly with a top edge, a base, an exterior wall with first and second sections, and an incline wall. The first section extends from the top edge to the base. The second section extends from the top edge to the inclined wall, and the inclined wall extends from the second section to the base. The transparent container assembly also comprises a first outlet. The fat harvesting container also comprises a lid assembly, a tubing assembly, and a first valve assembly. The inclined wall biases liquid matter towards the first outlet, thus facilitating its exit therethrough with minimum movement of liquid matter and fat matter within the transparent container assembly. This way liquid matter and fat matter remain separate and a probability of remixing is reduced and prevented.
