Deep well microplates are designed for specific use with absorbance, fluorescence, or luminescence testing methods for the most accurate results. Flat bottoms to give more surface area, round bottoms for mixing, or the best sample recovering conical bottom surfaces may come untreated or treated for specimen binding requirements. The deep well microplates are offered in various working volumes, sterility, and coloring for additional modifications. Common formats allow the devices to be compatible with efficient robotic processing.
