La présente invention concerne un appareil et un procédé de purification d'une substance à particules fines, l'appareil consistant en un appareil permettant d'améliorer la pureté d'une substance biochimique sous la forme d'une pluralité de particules fines et comprenant : un contenant externe présentant un volume prédéfini ; un premier élément comportant un trou traversant à travers lequel une substance complexe comprenant une substance biochimique peut passer, le premier élément étant formé à partir d'un matériau de filtre doté d'une pluralité de pores d'une taille inférieure à la substance biochimique ; et un moyen de transfert qui utilise une pression positive au niveau d'une extrémité et/ou une pression négative au niveau de l'autre extrémité de sorte que la substance complexe puisse passer à travers le premier élément, du gaz, un liquide, et des particules de taille inférieure aux particules de la substance chimique pouvant être évacués dans le contenant externe au moyen de la gravité et/ou de la gradation de pression lors du passage de la substance complexe à travers le premier élément.
