474 Chemistry pump device GP3 with cold trap and pump fork with aeration 1 1 Type GP3 is a mobile chemistry pump stand with a cold trap and a pump fork with a separate aeration cell. The pump fork has four independently switched vacuum valves and additionally four independently switched aeration valves, so that every sample holder can get individually evacuated or aerated. Through this type of assembling, every sample holder can get disconnected or aerated separately without affecting the vacuum of the other sample holders. Type GP3 has a small flange KF-NW 16 with vacuum manometer. Instead of the vacuum manometer you can also connect an electronic vacuum gauge. The pump stand will be delivered as standard without suitable vacuum pump.
