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

Main features 
1、Dry heating ( HGC Series) and water bath heating ( HSC Series) Two series can meet the usage needs of different users.        
2、Digital thermostat, dual digital display, adjustment PID Technology and can realize overtemperature alarm.       
3、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.
4、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.
5、HGC The specifications of the series are generally standard heating blocks φ15mm、φ17mm or φ21mm， The pore size and form of the special specification heating block can be pre-ordered.
