An apparatus and method of forming a solid-fibrin web. The apparatus includes a centrifuge ( 600 ) having a housing ( 604 ), and actuator ( 648 ), a wheel ( 660 ), and a flange ( 664 ). The housing includes a recessed area ( 616 ) and a base ( 608 ) supportable on a surface. The wheel is coupled to the actuator and extends into the recessed area and is adapted to contact a first end of a container ( 620 ). The flange extends into the recessed area opposite the wheel and defines an adjustable distance between the wheel and the flange. The flange is adapted to contact a second end of the container and the actuator is operable to rotate the container. The container is oriented substantially parallel with respect to the base.
