Centrifuge containment system

A containment system for a centrifuge comprising:

• a housing having a bottom and side walls extending therefrom terminating in a opening, said opening having a periphery positioned opposite to said bottom;
• a bowl disposed within said opening, defining a chamber, said bowl having a side portion extending from said periphery toward said bottom wall forming a terminus disposed opposite to said opening;
• a lid movably attached to said housing to selectively cover said opening;
• seal means, disposed between said lid and said periphery, for providing fluid-tight containment therebetween, upon said lid being positioned to cover said opening;
• a first annular member extending from said periphery inwardly toward the interior of said bowl, terminating in a free end and a second annular member inward of the side of the housing and spaced apart from the free end of the first annular member;
• and
• the first and second annular members having a spaced apart region extending toward said bottom wall with the second annular member extending downwardly from near the side portion of the bowl and the free end of the first annular member forming a trap effective as a decelerating means for decelerating matter traveling outwardly from said chamber toward said housing.

A containment system for a centrifuge having a lid, a rotor, a bowl and a housing, with said housing having side walls and a bottom wall extending between said side walls perpendicular thereto, defining a chamber with an opening, said opening disposed opposite to said bottom wall and having a periphery, with said bowl disposed within said chamber proximate to said periphery and having a side portion extending therefrom toward said bottom wall forming a terminus disposed opposite to said opening, said rotor being disposed within said bowl with said lid movably attached to said chamber to selectively cover said opening, said system comprising:

• seal means, disposed between said lid and said side walls, for providing said chamber with fluid-tight containment between said lid and said periphery upon said lid being positioned to cover said opening, defining a final seating position;
• an annular member extending from said periphery inwardly toward an interior of said chamber, terminating in an angled member, said angled member extending toward said bottom wall in spaced relation with respect to said side walls forming a gap therebetween, with said annular member, said angled member and said gap defining a trap means, disposed between said rotor and said lid, for preventing debris traveling away from said bottom wall toward said trap means from impinging upon said seal means;
• and
• an annular baffle extending downwardly from said lid, with said baffle adapted to seat proximate to said angled member upon said lid reaching said final seating position.
