Crystal growing cell

A crystal growing cell comprising:

• a first casing having a first solution chamber for containing a first solution therein, the first solution chamber having first and second openings;
• a second casing having a first closing member placed therein for movement in a first direction and in a second direction opposite to the first direction, the second casing having a first flexible casing placed therein, the first flexible casing being fixed to the first casing around the first opening to form a second solution chamber for containing a second solution therein;
• means for moving the first closing member in the first direction to close the first opening so as to separate the first solution chamber from the second solution chamber and for moving the first closing member in the second direction to open the first opening so as to connect the first solution chamber to the second solution chamber;
• a third casing having a second closing member placed therein for movement in a third direction and in a fourth direction opposite to the third direction, the third casing having a second flexible casing placed therein, the second flexible casing being fixed to the first casing around the second opening to form a third solution chamber for containing a second solution therein;
• and
• means for moving the second closing member in the third direction to close the second opening so as to separate the first solution chamber from the third solution chamber and for moving the second closing member in the fourth direction to open the second opening so as to connect the first solution chamber to the third solution chamber.
