PROBLEM TO BE SOLVED: To provide an apparatus and a method for supplying chemical solution which are capable of realizing highly reliable and stable chemical solution supply even if an interval of chemical solution supply becomes longer while surely preventing contamination.SOLUTION: A chemical solution supplying apparatus comprises: a chemical solution tank 15 which is installed in an outer space OUT and used for storing chemical solution for cell culture; a supply nozzle 60 which is installed in a workspace IN and used for supplying chemical solution to a culture vessel F; a chemical solution duct 10 for transferring chemical solution from the chemical solution tank 15 to the supply nozzle 60; a chemical solution duct 20 for transferring the chemical solution transferred by the chemical solution duct 10 to the chemical solution tank 15; and a duct switching part 50 for selecting a chemical solution supply mode in which the chemical solution duct 10 and the supply nozzle 60 are communicated with each other or a chemical solution circulation mode in which the chemical solution duct 10 and the chemical solution duct 20 are communicated with each other.SELECTED DRAWING: Figure 2 |
