Paterson Apparatus (PI-3) at the UMN Rock and Mineral Physics Laboratory. PI-3 was one of the first three commercially made Paterson apparatus and has been the workhorse of our lab since it was first installed in the early 90's. Confining pressures up to 300 MPa are generated by Argon gas. Temperatures up to 1250°C are generated by a furnace internal to the pressure vessel. A major benefit of this particular furnace design is the relatively small temperature gradient across the sample (~1°C over the entire sample length). A compensated actuator allows for axial compression and extension of samples that are on the order of 1 to 3 cm in length.
