As mentioned above, a crystal is formed following a well-defined pattern, or structure, dictated by forces acting at the molecular level. As a consequence, during its formation process the crystal is in an environment where the solute concentration reaches a certain critical value, before changing status. Solid formation, impossible below the solubility threshold at the given temperature and pressure conditions, may then take place at a concentration higher than the theoretical solubility … WebSeeds of the respective variant were prepared using an HR-320 PTFE Seed Bead (Hampton Research) following the manufacturer’s user guide. The concentration of crystalline PGA in the seed solution was estimated by the crystal yield of the crystallization prior to crystal crushing, assuming no crystal loss during crushing and dilution.
