Product Description:

QQMD200-1BThe nitrogen blower adopts a microcomputer andPIDFuzzy control technology uses high-purity aluminum material as a thermal conductive medium to replace traditional water bath devices, and has the characteristics of easy use, large temperature control range, and high accuracy. Mainly used for sample concentration or preparation (such as drug screening, hormone analysis, liquid phase, and sample preparation in mass spectrometry analysis). 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 twelve samples simultaneously, saving time and efficiency. This model of product has a unique feature: the liquid level position of the concentrated sample can be observed at any time during sample concentration.
1. The heater rapidly heats the sample to the evaporation temperature, while the gas is blown onto the surface of the solution through a gas needle, promoting rapid evaporation of the solution and concentration of the sample.
2. The height of the air chamber component can be adjusted, and this model of product has a unique feature: the liquid level position of the concentrated sample can be observed at any time during sample concentration.
3. Each air needle can be independently controlled, allowing for separate blowing and flow adjustment without wasting gas.
4. When concentrating toxic solvents, the entire system can be placed in a fume hood.
5. Built in over temperature protection device, automatic fault detection and alarm function.
6. LED display screen, temperature synchronous display, time decreasing display, easy and convenient operation. Can be set to run continuously at irregular intervals.
7. The product has a beautiful and elegant appearance, simple operation, safe and reliable use.
