Abstract
Sample disks are excised from a membrane by a cutting apparatus that includes a cutting tool terminating in a hollow cylinder with an exposed cutting edge, the tool slidably retained within a sleeve or otherwise slidably mounted to a mounting body, with a spiral cam in either the tool or the mounting body. A rider is included in the construction and arranged to engage the cam such that sliding movement of the cutting tool translates into rotational movement of the cylinder and its cutting edge.
