Pycnometer with acclimation chamber

A method for manufacturing an arrangement for measuring a volume of a solid or liquid sample, the method comprising:

• providing a first chamber for accommodating the sample;
• providing at least one second chamber connectable to the first chamber;
• providing a third chamber, being connectable to a gas supply source and being connected to a gas entry path leading to at least one of the first chamber and the second chamber;
• providing a temperature equalization system configured to temper at least the first chamber, the second chamber and the third chamber to substantially a same temperature;
• providing a pressure sensor;
• arranging and connecting plural gas paths comprising plural valves such as to allow,
• filling gas out of the third chamber into at least one of the first chamber and the second chamber, and
• measuring a pressure in at least one of the first chamber and the second chamber,
• wherein the temperature equalization system comprises:
• a metal assembly in thermal contact with the first chamber, the second chamber, the third chamber and at least a portion of at least one of the gas paths and in thermal contact with at least one of the valves,
• wherein the third chamber encloses a metallic material providing high surface area, wherein the metallic material is in thermal contact with the metal assembly,
• wherein the metallic material comprises at least one of:
• a fibrous web, a sintered structure, a loose material, a mesh, a fleece, a fabric, a non-woven fabric, a woven fabric, and a mat.
