The nitrogen blowing instrument produced by Shanghai Xinzhuang Instrument is divided into water bath nitrogen blowing instrument and program controlled temperature dry bath nitrogen blowing instrument. The difference is that the temperature control range is different. The water bath nitrogen blowing instrument is room temperature ~100 °C, and the dry bath nitrogen blowing instrument is room temperature~ 150 ° C, water bath nitrogen blowing instrument for experiment, you need to add water first, the temperature uniformity is good, dry bath nitrogen blowing instrument is heated by imported aluminum module, module specifications are optional, can be suitable for putting test tube diameter 15mm\16mm\19\mm The standard is 16mm.
Shanghai Xinzhuang Nitrogen Blowing Instrument is used for sample preparation in gas phase, liquid phase and mass spectrometry. It uses internationally recognized techniques to concentrate the sample by blowing nitrogen into the surface of the heated sample. The method has the characteristics of convenient operation and easy control, and can quickly obtain the expected result. The technology uses solid phase extraction pretreatment technology instead of traditional liquid phase extraction and chromatography technology to quickly separate and purify samples. Concentration with a nitrogen blow instead of a conventional rotary evaporator greatly shortens the analysis time.
The program controls the specificity of the nitrogen blowing instrument for different samples. The heating can be heated in five stages in different time periods, which bans the inadequacies of the ordinary heating nitrogen blowing instrument. It is mainly used for concentration or preparation of large-volume samples (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 dozens of samples, saving time and efficiency.
Features:
â—The heating method adopts program temperature control, and the program temperature control function is more powerful. The temperature and time can be divided into five sections for continuous operation.
â— Convenient module replacement for easy cleaning and disinfection.
â— Automatic fault detection and buzzer alarm function.
â— Temperature deviation calibration function, built-in over temperature protection device.
The heater heats the sample to the evaporating temperature while the gas is blown through the gas needle to the surface of the solution, causing rapid evaporation of the solution and concentration of the sample.
â— The position of the gas needle in the air chamber can be changed to suit different test tubes.
â—The height of the air chamber can be adjusted, and the standard gas needle length is 150mm.
â— There are 12 airway control switches that do not waste gas.
â— When concentrating toxic solvents, the entire system can be placed in a fume hood.
â— Built-in over-temperature protection device, automatic fault detection and alarm function.
â— LCD liquid crystal display, human-friendly touch interface, temperature synchronization display, time decrement display, easy to operate.
â— Standard air chamber and special adjustable bracket.
