SPECIFICATION
Product Description
The visible nitrogen blowing instrument is mainly used for sample concentration or preparation (such as sample preparation in drug screening, hormone analysis, liquid phase, and mass spectrometry analysis). Working principle: By blowing nitrogen gas into the surface of the heated sample, the solvent in the sample is quickly evaporated and separated, thereby achieving the goal of oxygen free concentration of the sample and maintaining its purity. Using a nitrogen blower instead of a commonly used rotary evaporator for concentration can simultaneously concentrate 12 samples, saving time and efficiency. This model of product has a unique feature: the liquid level of the concentrated sample can be observed at any time during sample concentration.
Product Features
1. The heater rapidly heats the sample to the evaporation temperature, during which the gas is blown to the surface of the solution through a gas needle, promoting rapid evaporation of the solution and sample concentration
2. The height of the air chamber component can be adjusted, and the standard length of the air needle is 150mm.
3.During sample concentration, the liquid level of the concentrated sample can be observed at any time.
4. Each blowing needle can be independently controlled, allowing for separate blowing and flow adjustment without wasting air
5.When concentrating toxic solvents, the entire system can be placed in a fume hood.
6. Equipped with built-in over temperature protection device, automatic fault detection and declaration function.
7. LED display screen, temperature synchronization display and time decrease display, simple and convenient operation. Can be set to run continuously from time to time
8. Standard equipment includes air chamber components and specialized adjustable brackets.
