Punches designed for automated cutting of several disc samples from a dry sample. These punches can usually cut simultaneously several samples of similar or different diameters (e.g., 1/16 to 1/4 inch, 1.6 to 6 mm) following a pre-chosen pattern, the disc samples are usually intended for insertion in titration plates. These punches typically consist of a computerized benchtop unit with a camera and a display to show the dry sample board and adjust the size and pattern of the punch holes, controls, and a dedicated firmware used to manage the operation of the machine using an external computer. Automated dry sample disc punches are mainly used to obtain disc samples from dry blood cards frequently obtained from dried blood spot samples taken from infants.
