Abstract

Systems and methods are provided for sample processing. A device may be provided, capable of receiving the sample, and performing one or more of a sample preparation, sample assay, and detection step. The device may be capable of performing multiple assays. The device may comprise one or more modules that may be capable of performing one or more of a sample preparation, sample assay, and detection step. The device may be capable of performing the steps using a small volume of sample.

First claim

What is claimed is:

1. A sample processing apparatus for use with a biological sample and/or a reagent, comprising:
a housing; and
a display screen mounted on the housing;
said housing containing the following:
at least one centrifuge;
at least one cytometer;
at least one optical detector;
a control unit having a processor that is programmed to execute non-transitory computer-readable commands; and
a sample handling system comprising at least a first pipette body and a second pipette body, wherein each of the first pipette body and the second pipette body is independently movable relative to each other and each comprises: a pipette nozzle, a motor, a geartrain, a valve, a lead screw, and a piston wherein each of foregoing is movable with said each of the pipette bodies together as a single unit.

2. The apparatus of claim 1 that is configured to dispense and/or aspirate 1 μL to 5 mL of fluid with a coefficient of variation of 5% or less.

3. The apparatus of claim 1 , further comprising at least one pipette body having a pipette nozzle configured to connect with a tip that is removable from said pipette nozzle, wherein the pipette has a height, width, and length each of which dimension does not exceed 20 cm.

4. The apparatus of claim 3 wherein the pipette body has a height which does not exceed 7 cm.

5. The apparatus of claim 1 , wherein the processor of the control unit is programmed to regulate the independent movement of at least one of said first pipette body and said second pipette body.

6. The apparatus of claim 1 , wherein both the first pipette body and the second pipette body are independently movable and independently controllable in relation to the other.

7. The apparatus of claim 3 , wherein the apparatus further comprises a processor programmed to regulate the independent movement of at least one of a positive displacement pipette body and an air displacement pipette head body.

8. The apparatus of claim 1 wherein at least one of the pipette body exhibits a coefficient of variation of 5% or less when handling a fluid volume of 5 μL or less.

9. The apparatus of claim 1 , wherein the processor of the control unit is programmed to regulate the independent movement of at least one of said first pipette head body and said second pipette body.

10. The apparatus of claim 1 , wherein said first pipette body is of a type that is different from said second pipette body.

11. The apparatus of claim 1 , wherein said first pipette body is of a size that is different from said second pipette body.

12. The apparatus of claim 1 , wherein the first pipette body is configured to aspirate a fluid having a volume no more than 100 μL.

13. The apparatus of claim 1 , wherein the pipette nozzle is configured to connect with a tip that is removable from the pipette nozzle, and wherein the tip is configured to hold a sample having a volume no more than 100 μL.

14. The apparatus of claim 1 , wherein the housing further contains a cartridge receiving location.

15. The apparatus of claim 1 , wherein the display screen comprises a touch screen.

16. A sample processing apparatus for use with a biological sample and/or a reagent, comprising:
a housing; and
a display screen mounted on the housing;
said housing containing the following:
at least one centrifuge;
at least one cytometer;
at least one optical detector;
a control unit having a processor that is programmed to execute non- transitory computer-readable commands; and

a sample handling system comprising at least a first pipette body and a second pipette body, wherein each of the first pipette body and the second pipette body is independently movable relative to each other and each comprises: a pipette nozzle, a motor, a geartrain, a valve, a lead screw, and a piston wherein each of foregoing is movable with said each of the pipette bodies together as a single unit;
wherein each pipette body has a pipette nozzle configured to connect with a tip that is removable from said pipette nozzle, wherein at least one of said first pipette body and second pipette body is configured to transport a fluid volume no more than 250 μL within or amongst a preparation station, assay station and/or detection station within the housing.

17. A sample processing apparatus for use with a biological sample and/or a reagent, comprising:
a housing; and
a display screen mounted on the housing;
said housing containing the following:
at least one centrifuge;
at least one cytometer;
at least one optical detector;
a control unit having a processor that is programmed to execute non- transitory computer-readable commands; and

a sample handling system comprising at least a first pipette body and a second pipette body, wherein each of the first pipette body and the second pipette body is independently movable relative to each other and each comprises: a pipette nozzle, a motor, a geartrain, a valve, a lead screw, and a piston wherein each of foregoing is movable with said each of the pipette bodies together as a single unit
wherein at least one of said first pipette body and second pipette body is configured to transport a fluid volume within or amongst a preparation station, assay station and/or detection station within the housing,
wherein the control unit executes computer-executable commands to monitor and evaluate performance of the one or more stations at any given addressable location, and based on said evaluation send instructions to said system to alter or maintain the performance of the one or more stations.

18. The apparatus of claim 17 wherein said evaluation identifies malfunctioning of the one or more stations wherein sending said instructions to said system effects correction of said malfunctioning.
