Dry-type Termovap Nitrogen Sample Concentrator TECHTONGDA® ITEM DESCRIPTION Each blow needle can be controlled independently to avoid cross-contamination. More uniform overall temperature, faster heating. LED display allows constant observation of temperature and time changes. This product can also be used as an ordinary dry thermostat. Wide range of applications, can be used for agricultural residues, biological, hormone analysis, sample concentration and pharmaceutical drug testing, etc. 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.
