automated liquid handlers, or liquid handling robots, is in verifying the proper function of the device. Liquid handling operations, performed by these automated systems, can fail due to clogged pipette tips, failed solenoid valves, damaged labware, operator error and many other reasons. A variety of methods exist for performing quality control of liquid dispensing on automated platforms including gravimetric, fluorescent and colorimetric measurements. In addition to manual quality control methods, technologies have been developed which allow for the automated monitoring of quality control of liquid handling robots. References Robotic manipulation
