ABSTRACT:
A method and apparatus for cutting cylinders of gelatinous material such as polyacrylamide gels into discs of precise thickness comprises a cutting surface which is placed in contact with the entire circumference of the cylinder. Cutting force is then applied from all points on the circumference at once, resulting in cutting the gel cylinder towards the center from all points on the circumference. This is accomplished by the use of a multi-bladed diaphragm similar to an iris diaphragm used for camera aperture control. The edges of the blades of the diaphragm form a variable dimension cutting surface.
