TECHTONGDA 110V Lab Nitrogen Evaporator Sample Concentrator Pressure Blowing Concentrator 12-Gas-Needles

Product description: Product Overview 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. Product Parameters Model:DN-12A Temperature range:room temperature 5℃-150℃ Timing time:A maximum of 99 hours 59 minutes Control accuracy:≤±0.5℃ Display precision:±0.1℃ Maximum gas pressure: 0.02Mpa (using the gas needle number less than 16) 0.05Mpa (using the number of gas needles more than 16) The number of holes:12 The diameter of each hole:16mm(0.63") Heating power:200W Fuse:250V 3A Ф5×20 Shape size:280X240X500mm(11.0*9.4*19.7inches) Net weight:11.9LBS Note: if you need other specifications, please contact us Item Included A set of Dry-type Termovap Nitrogen Sample Concentrator（056481）

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. Gas needle position in the gas chamber can be changed, suitable for various kinds of tubes. Equiped with 12 gas control switch ,no waste of gas. The entire system can be arranged in the ventilation cabinet when process concentration of toxic solvents.
