  • Patent number: 10919041
    Abstract: In a method of analyzing solid form properties of a substance, which including the step of solidifying the substance, the solidified substance is obtained in one of a plurality of wells of a multi-well plate. In the multi-well plate the at least one of the plurality of wells has a bottom made of a thermoplastic polyimide. The method further includes analyzing the solidified substance in the well of the multi-well plate by X-ray diffraction. Thereby, the analysis includes providing X-ray through the solidified substance and a bottom of the well and evaluating the X-ray which passed the solidified substance and the bottom of the well. Such method and multi-well plate provide a durable and cost efficient system allowing a high quality analysis of solid form properties of the substance and an efficient and safe processing of the substance.
