PURPOSE:To enable the pH adjustment of a culture solution by capillarity, by storing a small container putting a feed solution such as a pH adjustor, etc. to be added to the culture solution in a flask putting the culture solution, dropping a thread into both the solutions. CONSTITUTION:The small-sized container 2 putting the feed solution 3 such as a pH adjustor, a nutrient source, etc. is stored in the culture container 1 (Sakaguchi's flask, etc.), one end of the thread 4 is dipped in the feed solution 3, and the other end is dropped over the top of the wall of the small-sized container 2 into the culture solution 6. The feed solution 3 is fed along the thread 4 to the culture solution 6 by capillarity, and the supplied amount of the feed solution is adjusted to about 1-5mul/min by changing the tichkness of the thread or passing the thread 4 through the glass tube 5. |
