The design is described of a high pressure and temperature oedometer capable of simulating the migration of waste fluids through argillaceous sediments. Innovatory features are the methods of controlling the pressure and flow rate of the pore fluids, the hardfacing of the piston and cylinder containing the specimen and the provision of dynamic sealing which is stable at elevated temperatures and pressures over long periods of time.
