Patent ID: 8338167

Claim:
A pressure controllable incubation system for culturing living organisms, comprising: a pressure chamber that placing the living organisms to be cultured; a cylinder that is coupled with the pressure chamber, and stores air containing carbon dioxide at a concentration from 5% to 10% to be injected into the pressure chamber; a vacuum pump that is coupled with the pressure chamber, and discharges the air in the pressure chamber; a heat controller that detects temperature in the pressure chamber through a temperature sensor, and supplies heat directly to the pressure chamber based on the detected temperature by supplying electrical energy to a heat supply connected between the heat controller and the pressure chamber when the temperature in the pressure chamber is lowered; a pressure converter that detects pressure in the pressure chamber through a pressure sensor, and converts the detected pressure into a numerical value; and a monitor that displays the converted pressure value wherein the air stored in the cylinder, containing high-concentration carbon dioxide at a concentration from 5% to 10%, is discharged from the cylinder at a predetermined pressure and supplied to the pressure chamber, wherein the pressure chamber is maintained at a pressure 1 atm higher than the predetermined pressure, such that the concentration of carbon dioxide at the pressure chamber is maintained at 5±0.15%.
