Shanghai Jingqi Nitrogen Blower MD200-1, Shanghai Jingqi Instrument Co., Ltd. (CAT#: STEM-GLE-2243-YJL)

Shanghai Jingqi Nitrogen Blower MD200-1, model MD200-1 is manufactured by Shanghai Jingqi Instrument Co., Ltd.
MD200-1 Nitrogen Blowing Apparatus is mainly used in the concentrated preparation of large batches of samples, such as sample preparation in drug screening, hormone analysis, liquid phase, gas phase 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 sample anaerobic concentration and keep the sample more pure.
Using a nitrogen blowing device instead of a commonly used rotary evaporator for concentration can concentrate dozens of samples at the same time, which greatly shortens the sample preparation time, and has the characteristics of time saving, easy operation and quickness.

The heater heats the sample to the evaporation temperature quickly and effectively, and at the same time, the gas is blown from the gas chamber to the surface of the solution through the gas needle to promote the rapid evaporation of the solution and the concentration of the sample
Each purge needle can be controlled independently, and can be purged separately without wasting gas
The whole working system is composed of adjustable gas chamber and heater
The position of the air needle in the air cavity can be changed to make it suitable for different test tubes. The standard air needle length is 150mm
The height of the air cavity can be adjusted according to the height of the solvent liquid level. When concentrating toxic solvents, the whole system can be placed in a fume hood
Automatic fault detection and alarm function
Standard equipped with air cavity and special adjustable bracket
Built-in over-temperature protection device
Real-time temperature display, time decrement display
