Abstract

A system for handling sample vials includes a vault for receiving a series of storage cartridges. Inside the cartridges are one or more discs providing vial recesses. In multidisc cartridges, through passages are provided to place and retrieve vials into and from the subjacent discs. A pick up device is moved until it aligns with a selected vial and the vial is pneumatically removed. A device is provided to reverse orientation of a vial moving through the system. A venturi operated system is provided including symmetrical bleed off ports to propel vials through the system without inducing excessive spinning of the vials. A piping system from a central bank to a multiplicity of analytical instruments includes a minimum number of through conduits and a diverter at each instrument location for sending the vial either to the instrument or downstream toward another diverter and instrument.

6. The combination vault and storage cartridge of claim 1 wherein the only paths of vial movement into and out of the storage cartridge being through the at least one entry/exit opening.

7. The combination vault and storage cartridge of claim 1 further comprising a plurality of the storage cartridges adapted to be stored in a rack, wherein each storage cartridge housing is configured to be received in said docking station and includes

a storage device, carried by the housing, including information about the vials,

a communication link from the storage device to deliver information away from the storage cartridge, and

whereby the storage cartridges are interchangeable between the vault and the rack.

8. The combination vault and storage cartridge of claim 7 further comprising memory, in the storage device, for storing data.

9. The combination vault and storage cartridge of claim 7 wherein the input/output device is mounted for movement between the at least one entry/exit opening and the reader for

retrieving a vial from the storage cartridge,

then delivering the vial to the conduit.

10. The combination vault and storage cartridge of claim 7 wherein the drive mechanism, the input/output device and the control system are in the vault and not in the storage cartridge.

11. The combination vault and storage cartridge of claim 7 wherein the only paths of vial movement into and out of the storage cartridge being through the at least one entry/exit opening.

12. The combination vault and storage cartridge of claim 7 wherein the arrangement of the at least one entry/exit opening and sample holders in the disc allows only one vial at a time to move through the at least one entry/exit opening.

13. The combination vault and storage cartridge of claim 1 wherein the sample holders are arranged in concentric circular rows and the at least one entry/exit opening overlies only one sample holder in any rotational position of the disc.

14. The combination vault and storage cartridge of claim 13 wherein the at least one entry/exit opening comprises at least one entry/exit opening for each row of sample holder.

15. The combination vault and storage cartridge of claim 13 wherein the at least one entry/exit opening comprises a slot intersecting a plurality of rows of sample holders.

16. The combination vault and storage cartridge of claim 1 wherein there is at least one rotational position of the disc where the at least one entry/exit opening is misaligned with all of the sample holders in the disc thereby preventing loss of a vial.

17. The combination vault and storage cartridge of claim 7 wherein the arrangement of the at least one entry/exit opening and sample holders in the disc allows only one vial at a time to move through the at least one entry/exit opening.

18. The combination vault and storage cartridge of claim 1 wherein the sample holders are arranged in concentric circles and the at least one entry/exit opening overlies only one sample holder in any one position of the disc.

19. The combination vault and storage cartridge of claim 7 wherein the sample holders are arranged in concentric circles and the at least one entry/exit opening overlies only one sample holder in any one position of the disc.

20. The combination vault and storage cartridge of claim 19 wherein the at least one entry/exit opening comprises at least one entry/exit opening for each row of sample holders.

21. The combination vault and storage cartridge of claim 19 wherein the at least one entry/exit opening comprises a slot intersecting a plurality of rows of sample holders.
