    • PURPOSE:To accurately measure the culture soln. even in small amts. by arranging the detecting element of a sensor in the immediate proximity of the bottom edge of a flask where the culture soln. is always present even when the flask is shaken. CONSTITUTION:The sensor 8 for measuring the characteristics of a culture soln. while shaking the flask is inserted into the culture flask 1 through the sensor insertion port 3 provided to the flask 1. The extension of the center line 4 of the insertion port 3 crosses the bottom 5 of the flask, and the intersection is positioned at the edge 6 of the bottom 5 or in its vicinity. The detecting element 9 of the sensor 8 is placed close to the edge 6 of the bottom 5, and the sensor 8 is fixed. As a result, the characteristics of the culture soln. are accurately measured even when the amt. of the soln. is small. In addition, when the flask 1 is set in a shaker, the operation is facilitated, and the safety is enhanced.
