Six hole evaporative concentratorDuring the sample preparation process, samples that have undergone solvent extraction or solvent elution often contain a high amount of solvent, resulting in low concentrations of the analyte that are not suitable for direct injection analysis. Therefore, the solvent must be evaporated and concentrated. The evaporation concentrator introduced here uses compressed nitrogen gas commonly used in the laboratory, and adjusts the exhaust flow rate of stainless steel capillary tubes through needle valves, so that gas continuously flows on the surface of the sample, accelerating the evaporation of solvents and achieving sample concentration.
◆ Can process one to six samples simultaneously
Stainless steel needle valve control, equipped with a plug
◆ Three foot plastic hose
