Microtiter is a word used in the field of biomedical research to describe a multi-well plate used for the simultaneous processing and analyzing of samples. It has a capacity of up to 384 wells per plate allowing for high throughput testing. Although this term is widely used, some synonyms for a microtiter include a microplate, a well plate, and a multi-well plate. These terms are often used interchangeably in research circles, but have the same function and refer to the same type of laboratory tool. Ultimately, the usage of any of these synonyms will indicate the use of a high throughput plate that can help accelerate biomedical research projects.
