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 closed end defining a smaller footprint than said open end, 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.
2. A plate as in claim 1 , wherein said plate body is unitarily formed.
3. 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.
4. 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.
5. 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 generaly parallel.
6. 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 rectangular panel is formed with two side edges that extend between said closed end and said open end, said side edges being generally parallel, and
wherein each of said corners defining varying radiuses at different locations between said open end and said closed end including a first radius at a first location and a second radius at a second location, said first and second radiuses being different, and said first and second locations being different wherein said corners are disposed to be tapered at a constant taper angle between said open and closed ends.
