A portable hydraulic press for use in preparing metallurgical specimens, is disclosed herein, which requires relatively little force to operate and eliminates repumping during specimen preparation. The press includes a linkage assembly which connects an operating handle to a hydraulic jack in a manner such that both the mechanical advantage of the operating handle and ease of operation of the press is increased. In the embodiment shown, the press is constructed and arranged to provide ease of removal of the hydraulic jack without disassembling the entire press and includes a frame which stores energy.
