What’s the difference between an absorbance spectrophotometer and a microplate reader?

A standard spectrophotometer measures the absorbance of one sample at a time. The sample is typically placed in a cuvette through which light is sent horizontally. An absorbance plate reader offers higher throughput and can measure the absorbance of samples in microplates (typically 96-well or even 384-well) by sending light through each well vertically.
