Solid-phase extraction instrument is developed by combining liquid-solid extraction and liquid chromatography technology. It uses solid adsorbent to adsorb the target compound in the liquid sample, separate it from the matrix and interfering compounds of the sample Desorption or heating desorption achieves the purpose of separating and enriching target compounds (ie, sample separation, purification and enrichment), with the purpose of reducing sample matrix interference and improving detection sensitivity. It is used in various types of food safety testing, agricultural product residue monitoring, medicine and hygiene, environmental protection , commodity inspection, tap water and chemical production laboratories.

Anti-cross contamination, anti-atomization vacuum tank design, easy and fast operation
The whole machine is made of highly transparent organic glass
The guide needle and internal test tube rack are made of polytetrafluoroethylene, which is highly corrosion-resistant.
The extraction columns are evenly distributed, which facilitates group experiments, the extraction speed is uniform, and the control and adjustment are easy.
The vacuum tank has a uniform wall thickness, can withstand high negative pressure above -0.098Mpa, and is not easily deformed.
The extraction column tray is made of ultra-polymer material, which is corrosion-resistant and not easily deformed under high pressure.
