Abstract: A sample observation container and methods of use thereof are provided. The sample observation container includes a base and one or more sidewalls extending from the base. The one or more sidewalls form a sample enclosure for holding a sample undergoing a sample observation test such as sedimentation photographical capturing and dynamic light scattering, among other tests. The one or more sidewalls form a sample enclosure of adjustable cross-sectional area. The cross-sectional area may be adjusted by feeding or retracting a flexible sheet from a source roll to the sample enclosure. The cross-sectional area may further be adjusted by removing an innermost sidewall from among one or more nested sidewalls. The containers allow for physical adjustment of the cross-sectional area while performing subsequent sample observation tests, thereby allowing assessment of the effects of container size on the results of the sample, such as particles in liquid suspension.
