The Terminator is a device for cost-efficient high-throughput homogenization of plant material and sample preparation. Protein and DNA samples can easily be prepared from large numbers of crude material for further analysis such as protein electrophoresis or polymerase chain reaction (PCR) followed by DNA electrophoresis. The functioning of the device is based on vibration of 96 stainless steel pegs in wells of a standard 96-well micro plate. Using the Terminator all types of plant tissue, including seeds, can be homogenized in standard micro plates in 3 min.
