Nitrogen Evaporators are mainly used for the concentration and preparation of large quantities of samples, such as screening, hormone analysis, liquid chromatography, gas chromatography and mass spectrometry analysis. Working principle: By blowing nitrogen into the surface of the heated sample, the solvent in the sample is quickly evaporated and separated, so as to achieve the purpose of anaerobic concentration of the sample and keep the sample more pure. The Nitrogen Evaporator is used instead of the commonly used rotary evaporator for concentration, which can concentrate dozens of samples at the same time, greatly shorten the sample preparation time, and has the characteristics of time-saving, easy operation and speed.

● Each purge needle can be controlled independently, with 12 airway control switches, no gas waste.
● The heater makes the sample be heated to the evaporation temperature quickly and effectively, and the gas is blown to the surface of the solution from the gas chamber through the gas needle, which promotes the rapid evaporation of the solution and the concentration of the sample.
● The whole working system consists of an adjustable gas chamber and a heater.
● The position of the needle in the air cavity can be changed to make it suitable for different test tubes, and the standard needle length is 150mm.
● The height of the air chamber can be adjusted according to the height of the solvent level, and the whole system can be placed in the fume hood when concentrating toxic solvents.
● Automatic fault detection and alarm function.
● Equipped with air cavity and special adjustable bracket as standard.
● Built-in over-temperature protection device.
● Real-time temperature display, time decreasing display.
