Piston-cylinder apparatus



Kushiro-type press     4-post end-loaded press

Our piston-cylinder lab is comprised of two presses ('Kushiro-type press' and '4 post end-loaded press') used for experiments in the range of 0.5 to 3.5 GPa and at temperatures up to ~2500 degree C. Both presses accommodate 1/2 or 3/4 inch pressure cells.

machine specifications:

  • the 'Kushiro-type' press: a 3-post end-loaded press (~ 200 tons) designed for an 8 inch pressure plate (bomb); the end-load and primary-load rams are nested and are driven from the bottom.
  • the 4-post end-loaded press: the end-load ram is top-driven and the primary-load ram is bottom-driven; both rams have automated pressure control.

applications:

  • mineral-melt-fluid equilibria in lower crust and upper mantle
