Dry nitrogen blower MD200-2

The nitrogen blowing apparatus is mainly used for the concentration preparation of large quantities of samples, such as drug screening, hormone analysis, liquid phase, gas phase, and mass spectrometry sample preparation. Working principle: By blowing nitrogen into the surface of the heated sample, the solvent in the sample evaporates and separates quickly, thereby achieving the goal of oxygen free concentration of the sample and keeping it purer. Using a nitrogen blower instead of a commonly used rotary evaporator for concentration can concentrate dozens of samples simultaneously, greatly reducing sample preparation time, and has the characteristics of time-saving, easy operation, and speed

Product Features

Each blowing needle can be independently controlled and has 12 airway control switches, which does not waste gas.

The heater heats the sample quickly and effectively to the evaporation temperature, while the gas is blown from the gas chamber through the gas needle to the surface of the solution, promoting rapid evaporation of the solution and concentration of the sample.

The entire working system consists of adjustable gas chambers and heaters.

The position of the gas needle in the gas chamber can be changed to make it suitable for different test tubes The standard needle length is 150mm.

The height of the air chamber can be adjusted according to the height of the solvent liquid level. When concentrating toxic solvents, the entire system can be placed in a fume hood.

Automatic fault detection and alarm function.

Standard equipment includes an air chamber and a dedicated adjustable bracket.

Built in over temperature protection device.

Real time temperature display and time decreasing display.
