Calorimeter vessel with special lid construction - enabling opening for charging without additional space requirement

The calorimeter vessel does not require additional space provision for charging opening. The calorimeter vessel can be sealed air tight and the lid assembly has an inlet (4) and outlet (3) channel. The input channel consists of two cylinders arranged one inside the other and with apertures. The vol. of the input channel may be up to a quarter of that of the reaction vessel. The lid is sealed w.r.t the reaction cell by an O ring (5) after the cell has been overfilled. This prevents the entry of air into the cell. An alternative approach enables gas charging of the reaction liq. to be achieved by opening gas reservoirs in the cell.
