Abstract

The Invention is an apparatus and method for selectably sealing wells in a plurality of well plates. A plurality of lids and a plurality of gaskets are adapted to cover the wells of each well plate. A compression device is adapted to receive and to selectably compress the plurality of well plates, gasket and lids and to thereby selectably seal the wells of the well plate.

Claims

1. An apparatus for selectably sealing a plurality of wells in a plurality of well plates, the apparatus comprising:

a. a plurality of lids, each of said plurality of lids having a lower side and an upper side, each of the plurality of well plates having an upper surface and a lower surface, said upper side of each of said plurality of lids being adapted to engage said lower surface of one of the plurality of well plates;

b. a plurality of gaskets, each of said plurality of gaskets being adapted to engage said lower side of one of said plurality of lids, each of said plurality of gaskets further being adapted to engage said upper surface of one of said plurality of well plates;

c. a pressure plate;

d. a pressure surface in a spaced-apart relationship with said pressure plate;

e. a well-plate receiving space defined by said spaced apart relationship of said pressure plate and said pressure surface, said well-plate receiving space being adapted to receive the plurality of well plates, said plurality of gaskets and said plurality of lids, said pressure plate being adapted to selectably apply a pressure to the plurality of well plates, said plurality of gaskets and said plurality of lids thereby compressing each of said plurality of gaskets and sealing each of the wells in the plurality of well plates.

2. The apparatus of claim 1, further comprising:

a case, said case having a case bottom side and a case top side, said case bottom side defining said pressure surface, said case top side supporting said pressure plate.

3. The apparatus of claim 2 wherein said pressure plate has a first position and a second position, said pressure plate when in said second position applying said pressure to said plurality of well plates and lids, said pressure plate when in said first position not applying said pressure to said plurality of well plates and lids whereby the plurality of well plates and said plurality of lids may be removed from the apparatus when said pressure plate is in said first position.

4. The apparatus of claim 3, further comprising:

a lever cam, said case top side supporting said lever cam, said lever cam engaging said pressure plate, said lever cam adapted to select said first pressure plate position or said second pressure plate position.

5. The apparatus of claim 4 wherein said lever cam has a first lever cam position and a second lever cam position, said lever cam when in said first lever cam position selecting said first pressure surface position, said lever cam when in said second lever cam position selecting said second pressure surface position.

6. The apparatus of claim 5, further comprising:

a. said pressure plate comprises a plurality of said pressure plates, each of said plurality of pressure plates being supported by said case top side;

b. said case bottom side defines a plurality of said pressure surfaces, said plurality of pressure plates in combination with said plurality of said pressure surfaces defining a plurality of well plate receiving spaces.

7. The apparatus of claim 6 wherein each of said lids is configured so as to be sufficiently stiff to provide adequate distribution of said pressure to each of the wells of each of the well plates such that each of said gaskets seals each of said wells.

8. The apparatus of claim 7 wherein said lid is composed of a polystyrene plastic.

9. The apparatus of claim 8, further comprising:

said adaptation of said upper lid side to engage said lower well plate surface comprising a metal plate.

10. The apparatus of claim 9 wherein said metal plate is composed of a stainless steel bonded to said polystyrene by a pressure sensitive adhesive.

11. An apparatus for selectably sealing the wells in a well plate stack where each of the plurality of well plates within the well plate stack is covered with a gasket and a lid, the apparatus comprising:

a. a pressure plate;

b. a pressure surface in a spaced-apart relationship with said pressure plate;

c. a well-plate receiving space defined by said spaced apart relationship of said pressure plate and said pressure surface, said well-plate receiving space being adapted to receive the stack of well plates having the gasketed lids, said pressure plate being adapted to selectably apply a pressure to the stack of well plates having gasketed lids, thereby sealing each of the wells in the plurality of well plates.

12. The apparatus of claim 11, further comprising:

a case, said case having a case bottom side and a case top side, said case bottom side defining said pressure surface, said case top side supporting said pressure plate.

13. The apparatus of claim 12 wherein said pressure plate has a first position and a second position, said pressure plate when in said second position applying said pressure to said stack of well plates and gasketed lids, said pressure plate when in first second position not applying said pressure to said stack of well plates and gasketed lids.

14. The apparatus of claim 13, further comprising:

a lever cam, said case top side supporting said lever cam, said lever cam engaging said pressure surface, said lever cam adapted to select said first pressure surface position or said second pressure surface position.

15. The apparatus of claim 14 wherein said lever cam has a first position and a second position, said lever cam when in said first lever cam position selecting said first pressure surface position, said lever cam when in said second lever cam position selecting said second pressure surface position.

16. The apparatus of claim 15, further comprising:

a. said pressure plate comprises a plurality of said pressure plates, each of said plurality of pressure plates being supported by said case top side;

b. said case bottom side defines a plurality of said pressure surfaces, said plurality of pressure plates in combination with said plurality of said pressure surfaces defining a plurality of well-plate receiving spaces.

17. A method for selectably sealing a plurality of wells in a plurality of well plates, the method comprising:

a. providing a plurality of lids and a plurality of gaskets, said plurality of lids and said plurality of gaskets having a number, said number of said plurality of lids and said plurality of gaskets equaling a number of the plurality of well plates;

b. placing a one of said plurality of gaskets and a one of said plurality of lids on each of said plurality of well plates so that each of said lids and each of said gaskets covers an upper well plate surface, said plurality of well plates, said plurality of gaskets and said plurality of lids forming a plurality of covered well plate assemblies;

c. stacking each of said plurality of covered well plate assemblies so that a top side of one of said plurality of lids supports a lower surface of one of said plurality of well plates to form a well plate stack;

d. placing said well plate stack between a pressure plate and a pressure surface;

e. applying a pressure by said pressure plate to said stack of well plate assemblies whereby each of said plurality of gaskets is compressed and each of the plurality of wells in each of the well plates is sealed.

18. The method of claim 17, further comprising the additional step of:

a. releasing said pressure;

b. removing said stack of well plate assemblies from between said pressure plate and said pressure surface.

19. The method of claim 18 wherein said case has a case top side and a case bottom side, said pressure surface is defined by said case bottom side and said pressure plate is actuated by a lever cam supported by said case top side.
