Microphotographs of crystals of L-ascorbic acid. (a) Obtained using the traditional technique of slow evaporation (10 d) under an inert atmosphere used in an X-ray experiment, mounted on a MiTeGen MicroMount, and (b) obtained by fast crystallization from a spherical crystallization drop without any special precautions. Crystals obtained by the technique proposed here (b) are well faceted, while the crystal obtained by the traditional technique (a) has crooked facets (especially the upper and right facets, which are dark on the microphotograph). |
