Solid Phase Extractor

Solid-Phase Extraction (SPE) is a sample pretreatment technology developed by combining liquid-solid extraction and liquid chromatography. It is mainly used for sample separation, purification and concentration. Compared with traditional liquid-liquid extraction, it can improve the recovery rate of analytes, more effectively separate analytes from interfering components, reduce sample pretreatment process, simple operation, time-saving and labor-saving, and is widely used in food safety testing, agricultural product residue monitoring, medicine and health, environmental protection, commodity testing, chemical production and other fields.

▮  Performance and Features of Solid Phase Extraction Instrument
◾ The entire solid phase extraction instrument is made of highly transparent plexiglass for strong corrosion resistance.
◾ The vacuum chamber has uniform wall thickness, which prevents deformation even in high-pressure environments.
◾ The vacuum chamber design provides excellent sealing performance and high stability, ensuring uniform pressure distribution.
◾ The extraction columns are arranged in a square pattern, facilitating group experiments, ensuring uniform extraction speed, and enabling easy control and adjustment.
◾ Multiple channels can be independently controlled, and the guide needle is made of polytetrafluoroethylene for strong corrosion resistance.
◾ A vacuum gauge and exhaust valve are used to optimize sample flow rate.
