Introduction: The DC150-1B nitrogen blowing instrument adopts microcomputer and PID fuzzy control technology, and uses high-purity aluminum material as a heat-conducting medium to replace the traditional water bath device. It has the characteristics of convenient use, large temperature control range and high precision. Mainly used for sample concentration or preparation (such as drug screening, hormone analysis, liquid phase, and sample preparation in mass spectrometry). 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. Concentration using a nitrogen blower instead of a conventional rotary evaporator allows for the simultaneous concentration of twelve samples, saving time and efficiency. This model has a unique feature: the level of the concentrated sample can be observed at any time while the sample is being concentrated. Features: 1. The heater allows the sample to be rapidly heated to the evaporation temperature, while the gas is blown through the gas needle to the surface of the solution to promote rapid evaporation of the solution and concentration of the sample. 2. The height of the air chamber component is adjustable. This type of product has a unique feature: the liquid level of the concentrated sample can be observed at any time when the sample is concentrated. 3. Each gas needle can be independently controlled. It can be blown separately, and the flow can be adjusted separately without wasting gas. 4. When concentrating toxic solvents, the entire system can be placed in a fume hood. 5, built-in over-temperature protection device, automatic fault detection and alarm function. 6, LED display, temperature synchronization display, time decrement display, easy to operate. Can be set to run continuously from time to time. 7. The product is beautiful in appearance, simple in operation, safe and reliable in use.
