The utility model belongs to the field of microwave digestion technology and particularly relates to a constant-volume auxiliary device for a digesting inner tank. The constant-volume auxiliary device comprises a cylindrical constant-volume auxiliary component and a constant-volume volumetric pipet, wherein the cylindrical constant-volume auxiliary component comprises a constant-volume cylindrical section and a limiting cylindrical section which are integrated; the disc diameter of the constant-volume cylindrical section is matched with the inner diameter of the digesting inner tank to enable the constant-volume cylindrical section to slide into the digesting inner tank; the length of the constant-volume cylindrical section is smaller than the depth of the digesting inner tank; a leading flow hole is formed in the cylindrical constant-volume auxiliary component; the constant-volume volumetric pipet comprises a liquid outlet pipe section, a liquid storing pipe section and a liquid inlet pipe section which are
