Abstract
A thin multiwell plate for use in the transportation of microbes, animal cells, DNA, etc. The multiwell plate of the present invention comprises a sheet laminate, wherein the laminate has multiple hollow parts in which a water adsorbent material is retained. A multiplicity of microbe samples, etc. can be transported conveniently and safely by causing the water adsorbent material to retain a microbe-containing solution, a DNA sample solution, etc. In particular, an ultrathin multiwell plate can be provided due to construction with a sheet laminate, thereby rendering the transportation thereof extremely easy.
Claims5
A multiwell plate comprising:
- a body of laminated sheets and water adsorbent materials, wherein said body has plural hollow portions, each of which holds one of said water adsorbent materials,
- wherein said body of laminated sheets comprises,
- (a) a bottom sheet;
- (b) a removal sheet adhered on said bottom sheet and having plural through-holes;
- (c) a spacer sheet adhered on said removal sheet, having matching through-holes, wherein said through-holes of said removal sheet and said matching through-holes of said spacer sheet overlap with respect to each other,
- (d) a water adsorbent material fixing sheet adhered on said spacer sheet, having matching through-holes whose diameter is smaller than said through-holes of said spacer sheet, wherein said through-holes of said removal sheet and said spacer sheet;
- and said matching through-holes of said water adsorbent fixing sheet overlap with respect to each other, and further wherein said water adsorbent materials having diameters larger than the diameter of said through-holes of said water adsorbent material fixing sheet is adhered to said water adsorbent material fixing sheet and covers said through-holes of said water adsorbent material fixing sheet;
- and
- (e) a coversheet covering said water adsorbent material fixing sheet.
A multiwell plate comprising:
- a body of laminated sheets and water adsorbent materials, wherein said body has plural hollow portions, each of which holds one of said water adsorbent materials,
- wherein said body of laminated sheets comprises,
- (a) a bottom sheet;
- (b) a first spacer sheet having plural through-holes, in which each of said through-holes has a smaller diameter on a first face of said first spacer sheet and a larger diameter on a second face defining a stepped side wall within each of said through-holes, wherein said bottom sheet is adhered to said first face of said first spacer sheet;
- (c) a second spacer sheet having plural through-holes, in which each of said through-holes has a smaller diameter on a first face of said second spacer sheet and a larger diameter on a second face defining a stepped side wall within each of said through-holes, wherein said second face of said second spacer sheet is adhered to said second face of said first spacer sheet, further wherein said through-holes of said first and second spacer sheet overlap with respect to each other;
- and
- (d) a coversheet covering said first face of said second spacer sheet;
- wherein said water adsorbent materials having diameters larger than the smaller diameter of said through-holes is sandwiched between said spacer sheets.
