A sample holder for positioning and locking film for sample materials for spectroscopic analysis comprising a holder body having a cylindrical outer wall forming a cell adapted to contain the sample material and a ring member for biasedly pressing the film skirt against the cylindrical outer wall of the holder body in a first locking position. A locking bead around the ring member presses the film skirt into a locking groove around the cylindrical wall of the holder body in a second locking position. An optional third locking position is attained by a second locking bead around the biasable ring member pressing the film skirt into a second locking groove around the holder body. A method of assembling the film with the holder body and the ring member is also described.

A film handling, positioning, and locking system for a sample holder for sample materials for spectroscopic analysis, comprising, in combination: a body having a cylindrical wall comprising a cylindrical outer wall surface and a cylindrical inner wall surface defining therein a cell adapted to contain the sample material, said cylindrical wall having a circumferential first edge defining an open face of said cell, said cylindrical wall of said body having an outer diameter of a first predetemined value, film means positioned around said first edge and across said open face of said cylindrical wall for sealing said open face for the sample analysis, said film means including a film skirt for engagement with said cylindrical wall outer wall surface of said body, and cylindrical ring means having a cylindrical inner wall surface, the inside diameter of said cylindrical ring means having a second predetermined value less than said first predetermined value, when in its unbiased mode, said cylindrical ring means for biasedly pressing said film skirt against said cylindrical outer wall surface of said cylindrical wall of said body in a first locking position wherein said film skirt is tightly held between substantially the entire cylindrical outer wall surface of said cylindrical wall of said body and substantially the entire inner wall surface of said cylindrical ring means, said biasedly pressing being created by the attempted return of said ring means to its unbiased cylindrical mode to an inside diameter of said second predetermined value after said inside diameter has been increased to at least said first predetermined value to place ring means in its biased mode by the assembly of said ring means over said body and said film means; said ring means also positioning said film skirt relative to said cylindrical wall at a second locking position that prevents said ring means from moving axially from its position around said cylindrical wall of said body; said ring means also maintaining said film means across said open face of said cell sufficient to maintain a taut surface of said film means across said open face without imposition of undue strain upon said film.
