A device including a housing having an access opening, a swing arm mounted to the housing and configured to be selectively pivoted toward and away from the access opening, and a closure captured by the swing arm. The closure can be configured to be selectively moved in a substantially vertical motion relative to the swing arm between a retracted position and an inserted position at least partially in the access opening and can have locking features for cooperating with engagement features in the device to move the closure into a closed and sealed configuration.

An arrangement for measuring a volume of sample is disclosed. The arrangement includes a first chamber for accommodating the sample; at least one second chamber connectable to the first chamber; a first gas path including a first valve connected to the first chamber and on the other end connected to a gas entry path; a second gas path including a second valve, connected to the second chamber and on the other end connected to the gas entry path; a pressure sensor; a third gas path including a third valve, the third gas path connected to the first chamber and on the other end connected, via the third valve, to the pressure sensor; a fourth gas path including a fourth valve, the fourth path being connected to the second chamber and on the other end connected, via the fourth valve, to the pressure sensor.

An arrangement for measuring a volume of a solid or liquid sample includes a first chamber for accommodating the sample; at least one second chamber connectable to the first chamber; a third chamber connectable to a gas supply source and connected to a gas entry path leading to at least one of the first chamber and the second chamber; a pressure sensor; plural gas paths comprising plural valves; a temperature equalization system configured to temper at least the first chamber, the second chamber and the third chamber to substantially a same temperature, wherein the gas paths and the valves are arranged and connected 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.

This true density measurement device is a device that is used to measure the true density of a sample by a gas phase substitution method, and is provided with: a sample chamber for accommodating the sample, the sample chamber being pressurized through the introduction of an inert gas; and an expansion chamber into which is released the inert gas filling the sample chamber. The expansion chamber under conditions of normal use, is opened and closed by a detachable cover, and the volume thereof is modified by insertion or withdrawal of a volume modification member.

This true density measurement device is a device for measuring the true density of a sample by a gas phase substitution method, and is provided with a sample chamber for housing the sample, and a lid for providing closure to an opening of the sample chamber. The lid is a non-rotating lid that is pressed against the rim of the opening to hermetically seal the sample chamber.
