An apparatus (100) configured to simultaneously sample a plurality of seeds is provided. The apparatus (100) may include a grinder (110) configured to grind each of the seeds of a first plurality of seeds to produce a powder comprising a plurality of seed particles. A sample container (142) may be configured to receive the powder. Further, a cleaning device may be configured to introduce a neutral media to the grinder (110) to substantially prevent cross-contamination with a second plurality of seeds, which may be ground thereafter. The apparatus (100) may further comprise a mixing device (150) configured to mix the powder. Thereby a sample portion of the powder may be tested for the presence of a genetically modified organism, or other tests may be conducted thereon. A related method for high throughput simultaneous sampling of a plurality of seeds is also provided.
