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

Features

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.
4 HSC-A The height of the type test tube rack is adjustable, and can be flexibly adjusted according to actual needs and the aperture is fixed.

5 HSC-24B It adopts a spring design and can be used for test tubes, centrifuge tubes, volumetric flasks, beakers, etc. of different diameters. The nitrogen flow rate of each channel can be adjusted separately, which is convenient for handling different samples and saves gas source.
