The invention concerns a v-bottomed sample plate, a frame for sample plates and a kit and method for processing biological samples. The kit comprises a tray assembly and a plurality of sample plates designed to fit into the tray assembly. The tray assembly comprises a frame having a central plate receiving portion having a width and length, whereby said tray assembly is capable of accommodating the sample plates side by side in the plate receiving portion. Each of the sample plates contains a plurality of individual sample wells arranged in a grid, the dimension of the plate in a first direction being at maximum the width of the frame and the dimension of the plate in a second direction being at maximum half of the length of the plate receiving portion of the of the frame, and means for enabling automated handling of the plates. The invention enables more efficient biomedical processing of samples.

1. A kit for processing biological samples comprising a tray assembly and a plurality of sample plates designed to fit into the tray assembly, wherein the tray assembly comprises a generally rectangular frame having perpendicularly connected frame elements defining a central plate-receiving portion having a width and a length, whereby said tray assembly is capable of accommodating the sample plates side by side in the plate-receiving portion; andeach of the sample plates contains a plurality of individual sample wells arranged in a grid, the dimension of the plate in a first direction being at maximum the width of the frame and the dimension of the plate in a second direction being at maximum half of the length of the plate-receiving portion of the frame,wherein the sample plates are microtiter plates suitable for thermal cycling according to the PCR process, thus being of a v-bottom-type, whereby the sample wells are adapted to at least partially protrude through the plate-receiving portion of the frame,wherein the frame elements of the tray assembly comprise slots,wherein the sample plates comprise extensions on opposing ends thereof, each of the extensions further comprising a horizontal part and a vertical part extending from the horizontal part, wherein each of the extensions extends beyond the exterior edge of the tray assembly horizontally and beyond the bottom edge of the tray assembly vertically, andfurther wherein each of the vertical parts comprises a tip which is adapted to lock the plate into the tray assembly by slipping the tip into one of the slots. 2. A kit according to claim 1, wherein the plate-receiving portion comprises a central opening or central recess. 3. A kit according to claim 2, wherein the opening or recess is defined by the frame elements. 4. A kit according to claim 1, wherein the plate-receiving portion comprises a perforated plate having apertures for the individual sample wells. 5. A kit according to claim 1, wherein the sample plates completely cover the plate-receiving portion of the tray assembly when placed adjacent in the tray along the length of the recess. 6. A kit according to claim 1, wherein there are four sample plates. 7. A kit according to claim 1, wherein the tray assembly and the sample plates comprise mounting means for assisting positioning and immobilizing of the sample plates in the frame. 8. A kit according to claim 7, wherein the frame elements have wave-shaped inner edges for tightly fitting against the walls of the wells of the sample plates on at least some part of the frame. 9. A sample plate for holding a plurality of biological samples, the plate comprising a plurality of wells arranged in a grid having a predetermined pitch;extensions on opposing ends of the plate, each of the extensions further comprising a horizontal part and a vertical part extending from the horizontal part; anda tip being arranged on each of said vertical parts, with the tip arranged on one of the vertical parts extending in a direction toward the tip arranged on the other vertical part of the plate, with each tip being adapted to lock the plate into a plate-receiving frame by slipping into a slot provided on the plate-receiving frame,wherein the sample plate is a v-bottom type microtiter plate suitable for thermal cycling according to the PCR process. 10. A sample plate according to claim 9, wherein the outer dimensions of the plate correspond to the outer dimensions of a slide-sized microarray for enabling simultaneous compatibility with microfluidics devices and microarray handling equipment. 11. A sample plate according to claim 10, wherein the plate is, approximately, 75 mm by 25 mm in size. 12. The kit according to claim 1, wherein the means for enabling addition of the plates to the frame in an automated fashion by a robotic system also enables removal of the plates from the frame. 13. The kit according to claim 12, wherein said means for enabling addition of the plates to and removal of the plates from the frame in an automated fashion by a robotic system comprise slots arranged on extensions provided on opposite ends of the sample plates.
