A couette viscometer used to determine the rheological properties of Newtonian or non-Newtonian solid-laden or non-solid-laden fluids used as completion or treatment fluids in oil and / or gas wells. The instrument is capable of measuring the properties of a heated, e.g., 600° F. / 316° C., and pressurized sample, e.g., 30,000 psig / 207 MPa, at a variety of temperatures, pressures, and shear rates. The pressure vessel is mounted in the chassis of the instrument and the vessel plug containing the viscometer components and sample may be removed as an assembly. This arrangement reduces the mass of the plug assembly, eliminating the need to transport the pressure vessel and assists in separating the sample from the pressurizing fluid.
