A seed crusher e.g. useful in methods for high throughput analysis of seeds, comprises a horizontal well plate with at least one well for receiving a tube; an open-topped tube for lining each well wherein each tube is oriented for receiving a vertical reciprocating pin; a horizontal die plate with a vertical pin located to reciprocate in each tube; a removable separator for use in each tube to separate a reciprocating pin from a seed at the bottom of said tube and a press for bringing together the die plate and well plate to allow a pin to enter each tube.
