Automating combinatorial chemistry: a primer on benchtop robotic systems

Benchtop robotic systems are inexpensive, flexible automation tools with potential applications in a wide array of disciplines such as combinatorial chemistry, high-throughput screening, and genomics. We explain the basic components of a benchtop system and explore factors to consider when purchasing or customizing a robot, such as automation benefits, vendor selection, and current system limitations. Issues involving system specification, software design, and hardware customization are then discussed. Additionally, system optimization, validation, and support are detailed. Given a properly designed and implemented system, the combinatorial laboratory can markedly increase compound synthesis and purification.
