Product Numbers: NK200-IB
Product description: NDK200-1B visual nitrogen concentrator is mainly used for enrichment of large-volume sample or preparation (such as drug screening, hormone analysis, liquid phase, and mass spectrometry in the analysis of sample preparation). Working principle: the nitrogen into the heated surface of the sample and make the solvent t evaporate and separated rapidly, thereby reaching the sample enrichment purpose without oxygen, keep the sample purer. Nitrogen concentrator instrument can concentrated dozens of samples simultaneously, saving time and high efficient, instead of rotary evaporation instrument. This type of product has a unique feature: The liquid level position of sample concentration can be observed at any time.
Product features
1, The heater allows samples to be heated rapidly to the evaporation temperature, through the gas blow to the solution surface via needle at the same time, prompting rapid evaporation and concentration solution.
2, Gas needle position in the gas chamber can be changed, suitable for various kinds of tubes.
3, The gas chamber height can be adjusted, the length of standard gas needle is 80 mm.
4, Each blow needle can be controlled independently, can be blown, separate flow regulation, no waste of gas.
5, The entire system can be arranged in the ventilation cabinet when process concentration of toxic solvents,
6, Built in over-temperature protection device, automatic fault detection and alarm function.
7, LED display, temperature and time diminishing display, the operation is simple and convenient.
8, configured standard gas chamber and special adjustable bracket.
