Abstract
An apparatus for providing pressure to a sample. The apparatus comprises a housing having a cavity, an elastomer within the cavity, and a means for providing pressure to the elastomer within the cavity. The housing and the elastomer are configured to allow a sample to be inserted into the cavity, such that the sample is surrounded by the elastomer and such that the elastomer and the sample together fill the cavity.
Claims9
An apparatus for providing pressure to a sample, the apparatus comprising:
- a housing having a cavity;
- an elastomer within the cavity;
- a piston;
- wherein the housing and the elastomer are configured to allow a sample to be inserted into the cavity, such that the sample is surrounded by the elastomer and such that the elastomer and the sample together fill the cavity;
- and
- wherein:
- the cavity has a shape having an upper region with a first cross section, and a lower region with a second cross section which is greater in area than the first cross section;
- the elastomer extends into the upper region;
- a face of the piston is on one side of the cavity in the upper region;
- and
- piston provides a force to the elastomer in the upper region, and the apparatus is configured such that the sample is placed entirely in the lower region and is in contact with the elastomer.

A method of providing pressure to a sample, the method comprising:
- providing a housing having within it a cavity, wherein:
- the cavity has a shape having an upper region with a first cross section, and a lower region with a second cross section which is greater in area than the first cross section;
- the housing has a piston wherein one face of the piston is one side of the cavity in the upper region and the piston provides force to the elastomer in the upper region;
- inserting the sample into the cavity such that the sample is entirely in the lower region, the sample is surrounded by an elastomer and in contact with the elastomer, and such that the sample and the elastomer together fill the cavity and the elastomer extends into the upper region;
- applying pressure to the elastomer within the cavity via the piston.
