Product description: NDK200-1/2 Nitrogen Sample Concentration 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.Product features1. Heater heat the sample in the bottom and nitrogen blow on the surface to accelerate liquid for  evaporation and sample concentration.2. The position of gas needle in air cavity can be adjusted to suit for various tubes.3. The height of the air cavity can be adjusted. The length of a standard gas needle is 150mm.4. Gas needle is controlled independently. Separately blow of each needle and flow regulating of each needle are available to avoid gas waste.5. The entire unit can be working in ventilation cabinet when concentration poisonous sample.6. Built in overheat protection, automatic fault detection and fault beep alarm device.7. LED display immediate temperature and diminishing time. Operation is simple and convenient.8. Nitrogen sample evaporator configures air cavity and adjustable bracket.Technical ParametersModelNDK200-1NDK200-2Temp. Control RangeR.T. 5°C ~150°CR.T. 5°C ~150°CTemp.
