The Robot Coupe U.S.A., Inc. the inventor of sample prep machines over 35 years ago, has been the market leader and leading innovator of these machines through its Scientific/Industrial division (RSI). Robot Coupe offers a family of sample batch processors at significantly lower prices than comparable batch processors in the marketplace.

Bowl capacities for Robot Coupe sample prep machines range from 3 liters to 60 liters. Mixers are available as single, two-speed and variable-speed units. The variable speed mixers are used to blend, emulsify or homogenize food products; while the single and two-speed machines are used for size reduction of various products. The "S" blades for these processors are available with either 2- or 3-blade configuration depending on use and bowl size, and with smooth or serrated blades. All products placed in the Robot Coupe are fully processed due to the unique flat bottom bowl design. The bowl, lid and blade assembly are easily disassembled for cleaning; the bowl assembly can be place in a lab dishwasher for cleaning.
