    Introduction
    Solid-Phase Extraction (SPE) is a widely used and popular sample pretreatment technology. It uses solid sorbents to adsorb the target compounds in liquid samples and separate them from the sample matrix and interfering compounds. Then elute with eluent or heat desorption to achieve the purpose of separation and enrichment of the target compound. It is based on the traditional liquid-liquid extraction (LLE) based on the similar principle of similarity between substances and combined with the current widely used basic knowledge of liquid chromatography (HPLC) and gas chromatography (GC) stationary phases. ,
            In the solid phase extraction process, the attractive force of the solid relative analyte is greater than that of the sample mother liquor. When the sample passes through the SPE column, the analyte is adsorbed on the solid surface, and the other components pass through the column with the sample mother liquor, and finally the appropriate solvent is used. It elutes. SPE itself can be divided into four types according to its principle: reverse SPE (RP-SPE), positive SPE (NP-SPE), ion-exchange SPE (IE-SPE), and adsorption SPE (Absorption). In most cases, solid phase extraction is used to process liquid samples for the extraction, concentration, and purification of volatile and semi-volatile compounds in the sample. When solid samples are required, the solid sample must first be treated as a liquid.
    Features:
    1.Equipped with independent valves for each channel, easy to control, accurate control of flow rate, durable;
    2. The pressure gauge is installed above the sealing cover for easy observation;
    3. Test tube height adjustable to meet different needs;
    4. The use of special hard and thick glass in the degassing chamber, other parts are made of PTFE, have strong corrosion resistance;
    5. Anti-cross-contamination, anti-atomization vacuum tank design;
    6.SPE cartridges are stable in quality, high sample recovery, good precision, easy to collect analyte combinations, and can handle small volume samples;
    7.Can be equipped with large-capacity collector, rapid concentration of drying device, batch processing of samples, large-capacity collector, direct transfer of low-viscosity samples from the sample container to the solid phase extraction tube of Visiprep SPE vacuum sample processing device
    8. The vacuum tank has a uniform wall thickness so that it can withstand high negative pressures above -0.096 Mpa. Long-term high pressure use is not deformed.
    Technical Parameters:
    Overall size (mm): 280Wx122Lx186H
    Glass vacuum cylinder size (mm): 240Wx82Lx140H
    Pressure resistance: 0.098Mpa
    Air control method: Independent control of each hole
    Pressure display: There is an independent pressure gauge
