ABSTRACT:
An autoclave body is formed with a pressure chamber which has a closable ning; to permit rapid replacement of a rupturing membrane, the body is formed with a slot, channel, or notch, in which a strip of membrane material can be inserted, to be secured against the opening of the chamber by a quick-release movable pressure head, so that, upon rupturing of the membrane facing the pressure head, a new element of membrane material can be quickly placed over the opening of the chamber. The movable pressure head is hollow, with a cylinder opening facing the pressure head opposite the membrane side which closes the opening, and a piston is located in the hollow of the pressure head, to permit application of a vacuum to the side of the membrane not facing the opening of the pressure fluid chamber. The measuring cells are located diametrically opposite from each other, at an inclination with respect to the axis of the cell, so that the axes of the measuring elements face upwardly, to avoid entrapment of air bubbles at the faces thereof. At least a portion of the entire cell is formed with an internal chamber through which a thermostatically controlled temperature control fluid is circulated to maintain the cell at an event temperature.
