No reliable test presently exists for predicting the amount or type of corrosion a metal surface may experience during field use, particularly when the corrosion can be a result of both acid-induced corrosion and microorganism-induced corrosion mechanisms. Apparatuses affording more field-like testing conditions may comprise: a one-pass fluid train comprising a reservoir configured to maintain a fluid at a first temperature state under anoxic conditions; a pre-conditioning chamber in fluid communication with the reservoir and configured to receive a defined volume of the fluid; an autoclave chamber having an impeller in fluid communication with the pre-conditioning chamber that is configured to receive the defined volume of the fluid from the pre-conditioning chamber; and one or more sampling receptacles in fluid communication with the autoclave chamber that are configured to receive the defined volume of the fluid while maintaining anoxic conditions. The pre-conditioning chamber and the autoclave chamber are configured to maintain anoxic conditions at a second temperature state different than the first temperature state.
