Zusammenfassung:PURPOSE:To obtain the title flask capable of generating always stable boiling conditions without causing bumping by forming ruggedness on the inner surface of the bottom of the flask by shot blasting. CONSTITUTION:Sand grains 2, etc., are blasted on the inner surface 1a of the bottom of the flask 1 to form fine ruggedness 3. When a test liq. is charged in the obtain flask and the liq. is heated to its b.p., the liq. boils while generating fine bubbles from each ruggedness, and bumping is never caused. Moreover, the contact area between the test liq. and the flask bottom is increased by the ruggedness, hence heat efficiency is improved, energy is saved, and the testing time can be reduced.
