A multi-well microfiltration apparatus and method are provided and feature a manual touch-off system for transferring pendent drops hanging from discharge-conduits of a discharge-conduit array to respective receiving wells or receiving holes of a corresponding receiving array, with minimum or no cross-contamination between the discharge conduits, or the receiving wells or receiving holes. The manual touch-off is achieved by manually shifting a carriage that supports one of the arrays, into a position whereat pendent drops of fluid hanging from the distal ends of the discharge conduits contact the inner sidewalls of the corresponding receiving wells or receiving holes of the receiving array.

What is claimed is: 1. An apparatus, comprising: (i) a discharge conduit array comprising discharge conduits; (ii) a receiving array comprising receiving wells or receiving holes; (iii) a carriage configured to carry the discharge conduit array and adapted for movement along a first, generally horizontal, axis from and to a neutral position whereat the discharge conduit array and the receiving array are substantially axially aligned; (iv) a vertical positioning assembly configured for supporting the discharge conduit array for movement along a second, generally vertical, axis between (a) a first position whereat the discharge conduits of the discharge conduit array clear the receiving wells or receiving holes of the receiving array, and (b) a second position whereat the discharge conduits extend down into the receiving wells or receiving holes of the receiving array; and (v) a manually-operable handle connected to the carriage and the vertical positioning assembly and configured such that a movement of the handle moves the carriage along the first axis, and a second movement of handle moves the vertical positioning assembly along the second axis. 2. The apparatus of claim 1, wherein the handle is configured for pivotal movement from a beginning position to a set position, from the set position to an intermediate position, and from the intermediate position to a release position. 3. The apparatus of claim 2, wherein the handle includes two or more levers. 4. The apparatus of claim 2, wherein the beginning position is an elevated position, the set position is a depressed position, and the intermediate position is intermediate the beginning position and the set position. 5. The apparatus of claim 4, wherein the release position is the same as the beginning position. 6. The apparatus of claim 4, wherein the carriage is connected to the handle such that: when the handle is in the elevated beginning position, the vertical positioning assembly is in the elevated position; and when the handle is in the set position, the vertical positioning assembly is in the lowered position. 7. The apparatus of claim 4, further including a releasable lock wherein when the handle is depressed into the set position, the releasable lock is adapted to activate and maintain the vertical positioning assembly in the set position until the lock is released. 8. The apparatus of claim 1, further comprising a vacuum system for drawing a vacuum through the discharge-conduit array when the carriage is in the second position. 9. The apparatus of claim 1, wherein the first position is an elevated position and the second position is a lowered position. 10. An apparatus, comprising: a platform having a first treatment station and a second treatment station, the first treatment station including a holder for securing a first receiving array of receiving wells or receiving holes, and the second treatment station including a holder for securing a second receiving array of receiving wells or receiving holes; a carriage configured to carry a discharge-conduit array comprising discharge conduits into a position above the first receiving array at the first treatment station, and configured to carry the discharge-conduit array into a position above the second receiving array at the second treatment station, the carriage being configured for: (1) movement between the first treatment station and the second treatment station; (2) movement at the first treatment station along a first, generally horizontal, axis from a neutral position whereat the discharge-conduit array and the first receiving array are substantially axially aligned; and (3) second movement at the second treatment station along a second, generally horizontal, axis from a neutral position whereat the discharge-conduit array and the second receiving array are substantially axially aligned; a vertical positioning assembly for supporting the discharge-conduit array for linear movement at the first treatment station along a third, generally vertical, axis between (a) an elevated position whereat the discharge conduits clear the receiving wells or receiving holes of the first receiving array, and (b) a lowered position whereat the discharge conduits extend down into respective receiving wells or receiving holes of the first receiving array; and a manually operable handle connected to the carriage and the vertical positioning assembly such that a movement of the handle at the first treatment station moves the carriage along the first axis, a second movement of the handle at the second treatment station moves the carriage along the second axis, and a third movement of the handle moves the vertical positioning assembly along at least the third axis. 11. The apparatus of claim 10, wherein the handle is configured for pivotal movement at the first treatment station from a beginning position to a set position, from the set position to an intermediate position, and from the intermediate position to a release position. 12. The apparatus of claim 11, wherein the beginning position is an elevated position, the set position is a depressed position, and the intermediate position is intermediate the beginning position and the set position. 13. The apparatus of claim 12, wherein the handle is connected to the carriage such that movement of the handle to the release position translates into movement of the carriage into a transfer position whereat the carriage can be moved horizontally from the first treatment station to the second treatment station. 14. The apparatus of claim 13, wherein a carriage guide track is provided on the platform for guiding the carriage through a predetermined path from the first treatment station to the second treatment station. 15. The apparatus of claim 10, wherein the first treatment station comprises a sample wash station, and the second treatment station comprises a sample collection station. 16. The apparatus of claim 10, wherein the vertical positioning assembly supports the discharge-conduit array for movement at the second treatment station along a fourth, generally vertical, axis between (d) an elevated position whereat the discharge conduits clear the receiving wells or receiving holes of the second receiving array, and (e) a lowered position whereat the discharge conduits extend down into respective receiving wells or receiving holes of a second receiving array. 17. The apparatus of claim 16, wherein the handle is connected to the carriage and the vertical positioning assembly such that when the carriage is at the second treatment station movement of the handle translates into the movement of the vertical positioning assembly along the fourth axis. 18. The apparatus of claim 16, further including a releasable lock wherein when the handle is depressed into the set position in the first treatment station, in the second treatment station, or in both the first treatment station and the second treatment station, the releasable lock is adapted to activate and maintain the vertical positioning assembly in the set position until the lock is released.
