LID FOR A MICROTITER PLATE

1 - 15 . (canceled)

16 . A lid for a microtiter plate, which has a plurality of cavities, which are arranged on a top of the microtiter plate and serve for receiving samples,

wherein the lid is securable on the microtiter plate in such a manner that it covers at least the top of the microtiter plate,

wherein the lid has a basic body, which is embodied in such a manner that at least in regions, which are located above the cavities when the lid is on the microtiter plate, it is transmissive at least for light of at least one predeterminable wavelength, and

wherein the lid includes at least one closure element, which is embodied and/or arranged in such a manner that it closes at least one of the cavities in the microtiter plate when the lid is on the microtiter plate.

17 . The lid as claimed in claim 16 ,

wherein the basic body of the lid has a number of holes, wherein the holes are arranged in such a manner on the basic body that when the lid is on the microtiter plate they are located at least partially above the cavities.

18 . The lid as claimed in claim 17 ,

wherein an optical element is arranged in at least one of the holes.

19 . The lid as claimed in claim 16 ,

wherein the closure element is at least in regions, which are located above the cavities in the microtiter plate when the lid is on the microtiter plate, transparent at least for light of at least one predeterminable wavelength.

20 . The lid as claimed in claim 16 ,

wherein the closure element is a film.

21 . The lid as claimed in claim 16 ,

wherein the closure element is secured on a face of the basic body, which faces the microtiter plate when the lid is on the microtiter plate.

22 . The lid as claimed in claim 16 ,

wherein the closure element has an adhesive- or clinging layer on a face facing the microtiter plate when the lid is on the microtiter plate.

23 . The lid as claimed in claim 16 ,

wherein the basic body is embodied pot shaped in such a manner that the basic body has a floor portion, which is matched to the dimensioning of the top of the microtiter plate, and wherein the basic body has extending essentially perpendicularly to the floor portion a lateral portion, which at least partially surrounds the microtiter plate when the lid is on the microtiter plate.

24 . The lid as claimed in claim 16 ,

comprising at least one spacer, which is embodied and/or arranged in such a manner that, in a spacing position of the spacer the lid is arranged at a predeterminable distance from the microtiter plate or an additional lid when the lid is on the microtiter plate or the additional lid, and

the spacer is transferable into a closure position, in which the predeterminable distance is subceeded.

25 . The lid as claimed in claim 24 ,

wherein the spacer is transferable from the spacing position into the closure position by exerting a force.

26 . The lid as claimed in claim 23 ,

wherein the space holder is arranged in the region of the lateral portion of the basic body and protrudes at least partially into an internal volume formed by the lateral portion.

27 . The lid as claimed in claim 28 ,

wherein the basic body has at least one formation.

28 . A system comprising a microtiter plate and a lid comprising:

a lid for a microtiter plate, which has a plurality of cavities, which are arranged on a top of the microtiter plate and serve for receiving samples,

wherein the lid is securable on the microtiter plate in such a manner that it covers at least the top of the microtiter plate,

wherein the lid has a basic body, which is embodied in such a manner that at least in regions, which are located above the cavities when the lid is on the microtiter plate, it is transmissive at least for light of at least one predeterminable wavelength, and

wherein the lid includes at least one closure element, which is embodied and/or arranged in such a manner that it closes at least one of the cavities in the microtiter plate when the lid is on the microtiter plate.

29 . An automatable laboratory working space comprising:

a lid for a microtiter plate, which has a plurality of cavities, which are arranged on a top of the microtiter plate and serve for receiving samples,

wherein the lid is securable on the microtiter plate in such a manner that it covers at least the top of the microtiter plate,

wherein the lid has a basic body, which is embodied in such a manner that at least in regions, which are located above the cavities when the lid is on the microtiter plate, it is transmissive at least for light of at least one predeterminable wavelength, and

wherein the lid includes at least one closure element, which is embodied and/or arranged in such a manner that it closes at least one of the cavities in the microtiter plate when the lid is on the microtiter plate.

30 . An automatable laboratory working comprising:

a lid for a microtiter plate, which has a plurality of cavities, which are arranged on a top of the microtiter plate and serve for receiving samples,

wherein the lid is securable on the microtiter plate in such a manner that it covers at least the top of the microtiter plate,

wherein the lid has a basic body, which is embodied in such a manner that at least in regions, which are located above the cavities when the lid is on the microtiter plate, it is transmissive at least for light of at least one predeterminable wavelength,

wherein the lid includes at least one closure element, which is embodied and/or arranged in such a manner that it closes at least one of the cavities in the microtiter plate when the lid is on the microtiter plate, and

an apparatus affecting temperature of a sample.
