A lid for a well plate, which has pins that penetrate the lid and project downwardly into the wells of the well plate. Thermal energy is applied to the upper end of the pin to regulate the temperature of liquid samples. Ultrasonic energy is applied to the upper end of the pin to sonicate the liquid sample. An electrical charge is applied to the upper end of the pin to attract charged materials, such as DNA, and to selectably segregate charged materials from the liquid sample.

I claim: 1. An apparatus for manipulating a liquid sample stored in at least one well of a well plate, the apparatus comprising: a. a lid having an upper side and a lower side, said lower side of said lid engaging the well plate; b. at least one pin having an upper end and a lower end, said upper e
I claim: 1. An apparatus for manipulating a liquid sample stored in at least one well of a well plate, the apparatus comprising: a. a lid having an upper side and a lower side, said lower side of said lid engaging the well plate; b. at least one pin having an upper end and a lower end, said upper end of said at least one pin penetrating said upper side of said lid, said lower end of said at least one pin extending through said lid into the at least one well of the well plate, c. energy transfer means for selectively applying thermal energy, sonic energy, and/or electric charge in any sequence to or from said upper end of said at least one pin, said at least one pin transferring said applied energy or charge to or from the liquid sample. 2. The apparatus of claim 1, further comprising: a. said lower end of said at least one pin being in physical contact with the liquid sample; b. said energy transfer means comprising means to apply sonic energy to said upper end of said at least one pin, said at least one pin transmitting said sonic energy through said lid to the liquid sample, said sonic energy sonicating the liquid sample. 3. The apparatus of claim 2, said means to apply sonic energy to said upper end of said at least one pin comprising a sonic horn. 4. The apparatus of claim 3 further comprising: a. said sonic horn applying a mechanical pressure to said at least one pin; b. said at least one pin being resiliently connected to said lid such that said pin may move in response to said mechanical pressure by said sonic horn. 5. The apparatus of claim 4 said resilient connection of said at least one pin to said lid further comprising: a. said lid defining a hole conforming generally to said at least one pin; b. said hole having a cross-sectional area operably the same as or larger than a cross-sectional area of said pin, said pin being disposed within said hole; c. a resilient layer being disposed on the upper side of said lid; d. said upper side of said lid defining a plane, said at least one pin engaging said resilient layer such that said mechanical pressure applied to said at least one pin causes said at least one pin to move in a direction normal to said plane, said motion being resiliently opposed by said resilient layer. 6. The apparatus of claim 5, further comprising: said engagement between said lower side of said lid and the well plate being a sealable engagement, said degree of sealable engagement being selected so as to prevent escape of the liquid sample from the well when said means to apply sonic energy is sonicating the liquid sample. 7. The apparatus of claim 6 further comprising: a resilient gasket disposed between said lower side of said lid and the well plate, said sealable engagement between said lower side of said lid and the well plate comprising said gasket sealably engaging said well plate and said gasket sealably engaging said lid. 8. The apparatus of claim 7 further comprising: said energy transfer means comprising means to regulate the temperature of the upper end of said at least one pin, thereby regulating the temperature of the lower end of said at least one pin and regulating the temperature of the liquid sample. 9. The apparatus of claim 8, said means to regulate the temperature of the upper end of said at least one pin comprising a peltier device, a heat block, or a stream of heated or cooled air. 10. The apparatus of claim 9, further comprising: a. said at least one pin being capable of supporting an electrical charge; b. said energy transfer means comprising means to selectively apply an electrical charge to said at least one pin. 11. The apparatus of claim 10, further comprising: a. said means to selectively apply an electrical charge to said at least one pin comprising applying an electrical charge to said upper end of said at least one pin; b. said electrical charge being of sufficient magnitude and duration so as to cause electrical charge segregation of the liquid sample. 12. The apparatus of claim 1 further comprising: said at least one pin being resiliently connected to said lid such that said pin may move in response to a mechanical pressure applied to said upper end of said pin. 13. The apparatus of claim 12 said resilient connection of said at least one pin to said lid further comprising: a. said lid defining a hole conforming generally to said at least one pin; b. said hole having a cross-sectional area operably the same as or larger than a cross-sectional area of said pin, said pin being disposed within said hole; c. a resilient layer being disposed on the upper side of said lid; d. said upper side of said lid defining a plane, said at least one pin engaging said resilient layer such that said mechanical pressure applied to said at least one pin causes said at least one pin to move in a direction normal to said plane, said motion being resiliently opposed by said resilient layer. 14. A method for manipulating a liquid sample in a well of a well plate comprising the steps of: a. placing the liquid sample in the well of the well plate; b. placing a lid on the well plate, said lid having an upper side and a lower side, said lid having at least one pin having an upper end and a lower end, said pin penetrating said lid, said upper end of said pin extending to said upper side of said lid, said lower end of said pin extending into the well of the well plate, said lower end of said pin physically contacting the liquid sample; c. selectively and in any sequence applying thermal, sonic, and/or electrical energy to said upper end of said at least one pin, said pin transmitting said energy to said lower end of said at least one pin. 15. The method of claim 14, further comprising: said sonic energy being transmitted by said at least one pin to the liquid sample, said sonic energy sonicating the liquid sample; said lower side of said lid sealably engaging the well plate with a degree of sealable engagement selected so as to prevent an escape of the liquid sample during sonication of the liquid sample. 16. The method of claim 15 further comprising: said thermal energy being applied or removed by adding heat or removing heat from said upper end of said at least one pin, thereby adding or removing heat from the liquid sample. 17. The method of claim 15 further comprising: said applying of said electrical energy comprising applying an electrical charge of a sufficient magnitude and duration to said upper end of said at least one pin to attract an ion having an opposite charge from the liquid sample and reversibly binding said ion to said lower end of said pin. 18. The method of claim 17 further comprising: a. removing said lid from the well plate while said ion is bound to said at least one pin; b. engaging said lid with a second well plate, said second well plate having a well containing an appropriate reagent, said reagent physically contacting said lower end of said at least one pin; c. adjusting said electrical charge applied to said pin to selectably release said ion from said pin into said reagent.
