[0030] Working Principle: When using this invention, the power is turned on, the test tube is placed inside the main body 1 of the instrument, and the placement opening 101 is sealed by the sealing door 3. Simultaneously, the gas outlet column extends into the test tube. The test tube is heated by a water bath, and high-purity nitrogen from the nitrogen tube is delivered to the test tube through the gas guide tube and the gas outlet column. The inertness and inactivity of nitrogen effectively disperse the air on the solvent surface, reducing the gas partial pressure on the solvent surface and thus accelerating solvent evaporation. The sealing door 3 and the placement opening 101 are fixed by the protrusion 302 and the fastening bolt 303. The ventilation slot 103... It allows air from the outside to circulate with the air in the equipment chamber 102. The electric heating tube 201 generates heat when energized, and the blower 205 generates airflow. The airflow passes through the heating chamber 2 to form hot air, which is then delivered to the interior of the air chamber 203 through the air supply duct 202. The hot air is then blown onto the glass observation port 301 through multiple air outlets 204, which prevents water droplets from condensing on the glass of the observation port 301. At the same time, the vacuum pump 206 generates suction, which extracts the air from the placement port 101 through the air extraction chamber 207 and the air extraction hole 208, which reduces the air humidity inside the instrument body 1 and makes the water bath heating nitrogen blower work better.
