A method and device for processing mammalian adipose tissue such that the vascular rich fraction is separated from the vascular poor fraction, Mammalian adipose tissue in the form of morselated surgical biopsies and/or lipoaspirate from liposuction is placed within a novel syringe attached to a detection device measuring either color, light saturation, infra-red light, heme, iron or oxygen saturation. This process involves no label and minimal manipulation and handling of the tissue. This process and device may also be used intra-operatively under sterile conditions for immediate use within the same individual receiving liposuction or surgery.
