The crystallization processes in PFA tubes. The solution volume was 100–200 nl and the stirring conditions were as follows. (A) Continuous stirring (a) v = 5.3 × 10−4, Re = (4.7 ± 0.3) × 10−2, (b) v = 1.6 × 10−5, Re = (1.4 ± 0.1) × 10−3 and (c) v = 2.5 × 10−6 m s−1, Re = (2.2 ± 0.2) × 10−4. (B) Stirring period 4 s and resting period 4 min 56 s. v = 5.0 × 10−6 m s−1, Re = (4.4 ± 0.3) × 10−4. (C) Stirring period 4 s and resting period 14 min 56 s. v and Re under the stirring are the same as in cases (B) and (C). (D) Stirring period 4 min and resting period 11 min. v = 0.4 × 10−6 m s−1, Re = (3.5 ± 0.2) × 10−5. (E) Control experiment. Lysozyme crystals are marked by the black circles. |
