Introduction
The NDK200 series of nitrogen blowing instruments are mainly used for concentrated preparation of large quantities of 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
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.
3, the height of the air cavity can be adjusted, the standard gas needle length is 150mm.
4, there are 12 airway control switches, no waste of 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.
8. Standard air chamber and special adjustable bracket. Technical Parameters
