Multiwell plate
View Patent ↗A well geometry for multiwell plates is provided, wherein a well is formed with an open end, a closed end and a side wall extending therebetween, the side wall including four spaced-apart rectangular panels and four rounded corners. The corners are each located to join, and extend between, a pair of adjacent panels. With rounded corners, less wicking is experienced than with flat corners designs. In addition, the rectangular panels provide relatively larger perimeters than with comparable-sized trapezoidal-shape panels as viewed in various planes cutting through the well, particularly at the bottom of the well.
1. A multiwell plate comprising a plate body having a plurality of wells formed therein, at least a portion of said wells each being formed with an open end, a closed end and a side wall extending therebetween, said side wall including four spaced-apart rectangular panels and four rounded corners, each of said corners located to join, and extend between, a pair of adjacent said panels, wherein said corners each convergently taper towards respective said closed end.
2. A plate as in claim 1 , wherein said rectangular panels taper inwardly toward respective said closed end.
3. A plate as in claim 1 , wherein said plate body is unitarily formed.
4. A plate as in claim 1 , wherein said closed ends of said wells are at least partially formed by a separate base portion joined to said side walls.
5. A plate as in claim 1 , wherein said closed ends of said wells are at least partially formed by base portions unitarily formed with said side walls.
6. A plate as in claim 1 , wherein each said rectangular panel is formed with two side edges that extend between said closed end and said open end, said side edges being generally parallel.
7. A plate as in claim 1 , wherein each said corner includes two side edges that extend between said closed end and said open end, said side edges converging towards said closed end.
8. A multiwell plate comprising a plate body having a plurality of wells formed therein, at least a portion of said wells each being formed with an open end, a closed end and a side wall extending therebetween, said side wall including four spaced-apart rectangular panels and four rounded corners, each of said corners located to join, and extend between, a pair of adjacent said panels, wherein each said corner includes two side edges that extend between said closed end and said open end, said side edges converging towards said closed end.
9. A plate as in claim 8 , wherein at least a portion of said wells each converge toward respective said closed end.
10. A plate as in claim 9 , wherein said rectangular panels taper inwardly toward respective said closed end.
11. A plate as in claim 9 , wherein said corners each convergently taper towards respective said closed end.
12. A plate as in claim 8 , wherein said plate body is unitarily formed.
13. A plate as in claim 8 , wherein said closed ends of said wells are at least partially formed by a separate base portion joined to said side walls.
14. A plate as in claim 8 , wherein said closed ends of said wells are at least partially formed by base portions unitarily formed with said side walls.
15. A plate as in claim 8 , wherein each said rectangular panel is formed with two side edges that extend between said closed end and said open end, said side edges being generally parallel.
