NK200-1B visible nitrogen blowing instrument Introduction
The NK200-1B Visible Nitrogen Blower is primarily used for sample concentration or preparation (eg, drug screening, hormonal 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. This model has a unique feature: the level of the concentrated sample can be observed at any time while the sample is concentrated. Features
1. The heater causes the sample to be rapidly heated to the evaporation temperature, and the gas is blown to the surface of the solution by the gas needle to promote rapid evaporation of the solution and concentration of the sample.
2. The position of the gas needle in the air chamber can be changed to suit different test tubes. The standard gas needle length is 150mm.
3. The height of the air chamber can be adjusted. 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.
4. Each purging needle can be independently controlled, and the purging can be performed separately, and the flow rate can be adjusted separately without wasting gas.
5. When concentrating toxic solvents, the entire system can be placed in a fume hood.
6, built-in over-temperature protection device, automatic fault detection and alarm function.
7, LCD display, temperature synchronization display, time decrement display, easy to operate. Technical Parameters
