The LipoCollector® 3 is used to collect the lipoaspirate harvested in liposuctions, preferably water-jet assisted liposuctions (WAL), and to separate the ideally intact fat cells from the residual liquid for laboratory purposes or autologous fat transfer. The amount that can be collected in the LipoCollector® 3 under sterile conditions in a gentle and time-saving way is up to 1000 ml.
