Using purge and replenishment technology, nitrogen or other inert gases are used to quickly separate, purify and concentrate samples containing unknown and various types. This method is time-saving, convenient and accurate. It is widely used in pharmaceutical, medical testing, pesticide residue detection and other fields.

Application areas
（1）Analysis of pesticide residues: such as vegetables, fruits, grains, and plant tissues 
（2）Environmental analysis: such as drinking water, groundwater and contaminated water samples 
（3）Pharmaceutical testing: such as Chinese medicine 
（4）Biological analysis: such as serum, plasma, blood, urine 
（5）Drug inspection: such as dioxin, crotrotrol, etc. 
（6）Food and beverage: such as milk, wine, beer, liquid beverages

1 Digital thermostat, dual digital display, adjustment PID Technology and can realize overtemperature alarm.
2 The air needle channel on the distribution chamber can be used in combination or separately, and the height of the distribution chamber can be adjusted as needed.
3 Components that may come into contact with the solvent are made of 316 stainless steel, alloy aluminum, or plastic sprayed on the surface, which has a longer service life and is more convenient to clean.
