96-well BRANDplates are offered with four distinct well bottom shapes. A C-bottom is a flat bottom with curved edges. The C-bottom combines the advantages of U- and F-bottom. Because of the curved edges better sample mixing is obtained. The flat bottom in the middle of the wells at the same time allows the realization of precise optical measurements.
The C-bottom is widely used for immunological assays, as sample stirring has a major impact on precise assay results.
