Abstract: In a housing (1), an internal space capable of housing an insect is formed, an opening (11) through which the internal space and an outside communicate with each other is formed, and a portion other than the opening (11) is closed so that the insect is incapable of passing through the portion. Rails (2) in a pair are disposed in parallel with each other on both sides of the opening (11) across the opening (11) on an outer surface of the housing (1), maintain a gap between a face, on which the opening (11) is formed, of the housing (1) and a cover (3) to have a size preventing the insect from passing through the gap, and slidably retain the cover (3) on the external side of the housing (1). A sample holder retains a sample, is slidably retained by the rails (2), and enables the sample to be exposed from the opening (11) to the internal space when being slidably retained by the rails (2) in the state of retaining the sample.

Abstract: A sorption exothermicity measurement device (1) mainly includes: an air pump (2) that supplies dry air; a bubbling instrument (3) that humidifies dry air and supplies humidified air; a reaction measuring instrument (4) into which air flows so that the dry air or the humidified air comes in contact with a sample (10) to be measured; and a flow rate measuring instrument (5) that measures the flow rate of at least the humidified air flowing into the reaction measuring instrument (4). The reaction instruments are connected by flow paths through which the dry air or the humidified air flows. Furthermore, at least a humidified air supply system needle valve (13) that regulates the flow rate of the humidified air is included.
