ND300-1 Sample concentrator is a high precision temperature control instrument with microprocessor controlled and PID fuzzy controlled technique. It works by blowing nitrogen in the surface of sample which is being heated to accelerate evaporating and separating the solvent in the samples without oxygen. Instead of rotary evaporation instrument, nitrogen sample concentrator can efficiently concentrate a large of samples simultaneously.


 1. High precision and wide range of temp control.

 2. Blowing a large number of samples at one time.

 3. Blowing each sample independently.

 4. Easy operation; safe and reliable to use.


Application fields

a. Analysis of pesticide residues: vegetables, fruits, cereals, plant tissue.

b. Environmental analysis: such as drinking water, groundwater and polluted water samples.

c. Biological analysis: such as hormone analysis, sample preparation of liquid phase and gas phase and mass spectrometry analysis.

d. Food and beverage: such as milk, wine, beer, etc.

e. Pharmaceutical drug testing: such as traditional Chinese medicine pharmaceutical, drug screening.
