Microtitation plate

1. A microtitration plate, comprising:

a frame ( 2 , 8 ) which is made of at least one laser-inscribable plastic in at least one area ( 13 ), and

a multiplicity of receptacles ( 9 ) arranged in the frame and having an opening ( 10 ) on one side of the frame ( 2 , 8 ) which are made of a plastic other than the laser-inscribable plastic

wherein the frame ( 2 , 8 ) has a plate ( 2 ) in which the receptacles ( 9 ) are formed or to which the receptacles ( 9 ) are connected,

wherein the microtitration plate has at least one laser-made inscription ( 14 , 15 ) on the frame ( 2 , 8 ) in the at least one area ( 13 ), wherein the receptacles ( 9 ), a central area ( 12 ) of the plate ( 2 ) that is connected to the receptacles ( 9 ), a jacket ( 8 ) of the frame that surrounds the plate, and webs ( 18 ) connecting the central area ( 12 ) to the jacket ( 8 ) are made of the same plastic other than the laser-inscribable plastic and one area ( 13 ) of the frame ( 2 , 8 ) that is disposed between the central area ( 12 ) of the plate ( 2 ) and the jacket ( 8 ) is made of the laser-inscribable plastic completely or at least in part,

further wherein one area ( 13 ) of the plate ( 2 ) that surrounds all of the receptacles ( 9 ) in a frame-like manner is made of the laser-inscribable plastic completely or in at least one area.

2. The microtitration plate according to claim 1 wherein the plate ( 2 ) is made of the laser-inscribable plastic in at least one area ( 13 ).

3. The microtitration plate according to claim 1 wherein an upper layer of the frame ( 2 , 8 ) is made of the laser-inscribable plastic completely or in at least one area.

4. The microtitration plate according to claim 1 wherein the laser-inscribable plastic is of a color other than that of areas of the frame ( 2 , 8 ) that cannot be inscribed by a laser, and/or that of the receptacles ( 9 ).

5. The microtitration plate according to claim 1 which comprises a plurality of areas ( 13 ) made of a laser-inscribable plastic of different colors.

6. The microtitration plate according to claim 1 wherein the laser-inscribable plastic has an adhesive bond and/or a joint via counterdrafts and/or a latched joint with adjacent areas of the frame ( 2 , 8 ) and/or the receptacles ( 9 ).

7. The microtitration plate according to claim 6 wherein the adhesive bond is a fusion of various plastics or a bond of various plastics via an adhesive substance.

8. The microtitration plate according to claim 1 wherein the laser-inscribable plastic comprises a basic material including a laser additive.

9. The microtitration plate according to claim 8 wherein the basic material essentially is the same as the plastic of frame areas which cannot be inscribed by a laser and/or the plastic of the receptacles ( 9 ).

10. The microtitration plate according to claim 8 wherein the basic material of the laser-inscribable plastic is PP or PS or another thermoplastic substance or thermoplastic elastomer.

11. The microtitration plate according to claim 1 wherein the laser-inscribable plastic is PC or PVC or another plastic which can be inscribed by a laser not including laser additives.

12. The microtitration plate according to claim 1 wherein the plastic of areas of the frame ( 2 , 8 ) is PP, PS, or another thermoplastic substance or thermoplastic elastomer.

13. The microtitration plate according to claim 1 wherein the receptacles ( 9 ) are made of a transparent plastic at least in part.

14. The microtitration plate according to claim 1 which has a laser-made inscription ( 14 , 15 ) the color of which is different from that of areas of the frame ( 2 , 8 ) and/or that of the receptacles ( 9 ) that cannot be written by a laser.

15. The microtitration plate according to claim 1 wherein the laser-made inscription is a receptacle identifier ( 14 , 15 ) including a series of numbers and a series of letters for an identification of each receptacle ( 9 ) of the microtitration plate and/or a plate identifier ( 18 ) for an identification of the entire microtitration plate and/or a manufacturer's identifier ( 17 ) or position identifier ( 16 ) to mark the orientation of the microtitration plate.

16. The microtitration plate according to claim 15 which has the position identifier ( 16 ) at a corner of the frame ( 2 , 8 ).

17. The microtitration plate according to claim 15 which has the series of numbers of the receptacle identifier ( 14 , 15 ) at one side of an area ( 12 ) of the frame ( 2 , 8 ) that surrounds a central area ( 12 ) of the frame ( 2 , 8 ) in a frame-like manner and has the identifier consisting of letters at a side perpendicular thereto of the area ( 13 ) of the frame ( 2 , 8 ) that surrounds the central area ( 12 ) of the frame ( 2 , 8 ) in a frame-like manner.

18. The microtitration plate according to claim 15 wherein the plate identifier ( 18 ) is a line code (bar code) or a two-dimensional dot code (Dot Matrix Code).
