Patent ID: 8720255

Claim:
A water uptake measurement system for measuring uptake of a fluid by a sample, comprising: a sample chamber having an outer surface, an inner surface, an internal cavity having a controlled temperature and humidity, and a suspension aperture that is located at a first end of the sample chamber, wherein the suspension aperture extends from the outer surface of the sample chamber to the inner surface of the sample chamber; a suspension component that passes through the suspension aperture of the sample chamber such that a first end of the suspension component is located in an ambient temperature and humidity area outside of the internal cavity of the sample chamber and a second end of the suspension component is suspended within the internal cavity of the sample chamber, wherein the suspension component is configured to support the sample within the internal cavity such that the sample is spaced apart from the inner surface of the sample chamber, and the suspension aperture is sized and configured to allow the suspension component to pass therethrough and to minimize temperature and humidity losses from the internal cavity to the ambient temperature and humidity area; and a supply interface that is configured to deliver the fluid to the internal cavity of the sample chamber.
