Ultrafiltration apparatus employing collodion bag dialyzing means. This apparatus provides a means for accelerating the dialysis process and a cooperative means for obtaining samples of the concentrate from the collodion bag. A displacement body with an axial bore is attached to a tube and positioned within the collodion bag. By displacing fluid volume in the bag, the speed of dialysis is increased. The combination of the tube and displacement body also facilitates removal of samples of the concentrated fluid from the bag.
