Method for purifying adipose tissue and associated purified adipose tissue

A method for purifying adipose tissue, comprising:

• addition of a washing liquid to an adipose tissue to be purified comprising contaminants and present in a treatment volume delimited by means of retention of the adipose tissue and filtration of the contaminants,
• filtration of a fraction of the contaminants of the adipose tissue contained in the washing liquid by centrifuging the contents of the treatment volume by rotating the retaining and filtering means, and
• a discharge of the washing liquid containing the filtered fraction of contaminants,
• wherein a preliminary filtration of a fraction of the contaminants present in an interstitial liquid of the adipose tissue to be purified in the treatment volume is carried out before the addition of the washing liquid, by centrifuging the contents of the treatment volume by rotating the retaining and filtering means.
