1. A method for separation of components of a fluid mixture, the method including the steps of:
loading a vial with the fluid mixture, the vial having a first end opposite a second end, and with a collapsible sidewall extending at least partially between the first end and the second end, and with an inlet spaced from the first end;
rotating the vial in a centrifuge about a rotational axis, with the first end further from the rotational axis than the second end, until the fluid mixture is at least partially separated into at least two components, including a first component and a second component, the first component closer to the first end of the vial than the second component;
ejecting at least a portion of the second component of the fluid mixture from the vial through the inlet by collapsing the sidewall of the vial to reduce vial volume; and
wherein said loading step includes the vial having a bulb adjacent to the first end, and with a neck extending from the bulb toward the second end, said bulb having a larger cross-sectional area perpendicular to a long axis, extending between the first end and the second end, than a cross-sectional area of the neck.
