Fig. 3From: A highlightedly improved method for isolating and characterizing calcium oxalate crystals from tubercles of Mammillaria schumanniiThe method of collecting CaOx crystal through differential centrifugation after the mechanical blending. Blending the tubercles of Mammillaria schumannii, large-sized crystals settled down at the bottom of the blender. After collecting, three centrifugations of the blended solution were performed in order to separate the small-sized crystals from the plant tissues (A)Back to article page
