Abstract
Apparatuses and methods for cutting a sample piece, having a shape and an outer dimension, out of a porous substrate, comprising: a puncher having an outermost dimension at a punch head; a stripping sleeve; a die having an innermost dimension that is larger than the outermost dimension of the punch head; and a fixture that holds the die in a fixed position relative to the puncher and stripping sleeve.
Claims20
An apparatus for cutting a sample piece, having a shape and an outer dimension, out of a porous substrate, comprising:
- a puncher having an outermost dimension at a punch head;
- a stripping sleeve;
- a die having an innermost dimension that is larger than the outermost dimension of the punch head;
- and
- a fixture that holds the die in a fixed position relative to the puncher and stripping sleeve,
- wherein the apparatus further comprises one or more guides and one or more channels corresponding to the one or more guides and
- wherein the fixture comprises a pillar that comprises a seat for the one or more guides, and the one or more channels are located on the stripping sleeve.
An apparatus for cutting a sample piece, having a shape and an outer dimension, out of a porous substrate, comprising:
- a puncher having an outermost dimension at a punch head;
- a stripping sleeve;
- a die having an innermost dimension that is larger than the outermost dimension of the punch head, wherein the die has an upper end and a lower end and an inner diameter that is larger on the lower end than an inner diameter on the upper end, wherein the inner diameter of the die increases gradually from the upper end to the lower end;
- and
- a fixture that holds the die in a fixed position relative to the puncher and the stripping sleeve.
