The NK200-2N Dual Block sample concentrator is mainly used for the concentration or preparation of bulk samples (such as drug screening, hormone analysis, liquid phase, and sample preparation in mass spectroscopy). Working principle: By blowing nitrogen into the surface of the heated sample, the solvent in the sample is quickly evaporated and separated, thereby achieving the purpose of anaerobic concentration of the sample and keeping the sample more pure.
Features: The heater heats the sample rapidly to the evaporation temperature, and at the same time, the gas is blown to the surface of the solution through the gas needle, which promotes rapid evaporation of the solution and concentration of the sample. The height of the air cavity can be adjusted. The length of a standard gas needle is 80mm. The entire equipment can be put into ventilation cabinet when the concentration sample in toxic solvents. Built in overheat protection, automatic fault detection and fault beep alarm devices. LED displays immediate temperature and diminishing time.
