主权项

1. An automated bioprocessing device comprising:
a) a housing; b) a cover; c) one or more first sample holders, said first sample holder holds one or more biological samples; d) one or more removable washing basin assemblies on said housing, each washing basin assembly comprising at least 2 washing basins, each washing basin configured to store a processing fluid, each washing basin configured to receive said first sample holder, each washing basin configured to be of the same or different volume; e) one or more robot assemblies on said housing, each robot assembly configured to transport said first sample holder and said biological samples therein from one said washing basin to another said washing basin, and to agitate said biological samples within said washing basin; and f) a control system configured to operate said robot assembly according to a predetermined schedule, said control system comprising at least one bioprocessing controller; wherein said first sample holder is selected from a group consisting of a second sample holder and a third sample holder; said second sample holder comprises:
i) a cylinder chamber configured to hold said biological sample;ii) a plurality of bumps on an inside surface of said cylinder chamber;iii) a cap on an end of said cylinder chamber, said cap configured to connect said second sample holder to said robot assembly; andiv) a plurality of first openings on said cylinder chamber and said cap whereby the free flow of said processing fluid is allowed; and said third sample holder comprises:
i) a first chamber, said first chamber made from bendable materials and configured to hold said biological samples;ii) a plurality of second openings on said first chamber whereby the free flow of said processing fluid is allowed; andiii) a rotation reel inside said first chamber, said rotation reel configured to be controlled by said robot assembly to hold and rotate said first chamber.
