Sample Concentrator，BNNC-A2

1.The height of the air chamber plate can be adjusted. The length of a standard gas needle is 150mm.
2.LED displays immediate temperature and diminishing time. Operation is simple and convenient.
3.Built in overheat protection, automatic fault detection and fault beep alarm devices.
4.The entire equipment can be put into ventilation cabinet when the concentration sample is in toxic solvents.
5.Synchronously working with heating by dry bath in the bottom and nitrogen blowing on the surface accelerates liquid evaporation and sample concentration.
6.Unique patented design for air channel control system, enhances air tightness and reduces potential leakage; easy to operate, lift/press air needle to realize
channel switch; the switching status of each channel is clear at a glance.
7.Standard configured air cavity and adjustable bracket.

The sample concentrator is mainly used for the concentration or preparation of bulk samples (such as drug screening, hormone analysis, liquid phase, and sample preparation in mass spectrometry). Working principle: By blowing nitrogen into the surface of the heated sample, the solvent in the sample is quickly evaporated and separated, thereby achieving the purpose of anaerobic concentration of the sample and keeping the sample more pure
