The instrument consists of a base and stand assembly, sample holder and gas distribution system. Test tubes are held in a bolck . The gas at 5 to 10 psig passes through the distribution manifold. Depending on the test-tube size and solvent volume they can be individually raised or lowered to the correct height. Needles or glass pipets blow gas onto the surface of the solution resulting in rapid evaporation of the solvent. All materials used are laboratory quality and can withstand contact with organic solvents. Acid resistant models are available for corrosive application Features 1. High precision and wide range of temp control 2. Blowing a large number of samples at one time 3. Blowing each sample independently 4. Amount of airflow can be adjusted 5.
