Name: SPE rapid pretreatment device for aquatic products and animal husbandry products

Solid phase extraction (SPE) is a physical extraction process that includes liquid and solid phases. In the extraction process, the adsorption force of the solid to the analyte is greater than the sample mother liquid. When the sample passes through the SPE column, the analyte is adsorbed on the solid surface, and other components pass through the column with the sample mother liquid, and then the analyte is removed with an appropriate solvent Eluted down. SPE has a wide range of applications, such as the analysis of biological fluids including blood, urine, serum, plasma and cytoplasm; the analysis of milk processing, wine, beverages and juices; the analysis and monitoring of water resources; fruits, vegetables, grains, and various plant tissues. Animal tissues; tablets and other solid medicines. Analysis of pesticide and herbicide residues in fruits, vegetables and foods, analysis of antibiotics and clinical drugs, etc

The oil-free vacuum pump is advanced in design, compact and reasonable in structure, small in size, light in weight, convenient to move, stable in operation, high in vacuum, low in noise, high in work efficiency, and long in service life. According to the needs of the operator, filter membranes with different materials and different filter pore sizes are selected to achieve the functions of removing impurities in the solvent, purifying and sterilizing. In chromatographic analysis, the solvent filtered by it can not only effectively extend the service life of the chromatographic column, but also because of its vacuum removal effect, it also significantly improves the data accuracy of the analysis system. It can be used directly with solvent filter, solid phase extraction instrument, multiple filter, vacuum drying oven, etc.

Application range:

is suitable for SPE small column purification process, modular design, ≥12 positions.

Independent flow path to prevent cross-contamination. Anti-fogging vacuum tank design, simple and fast operation.

Flexible use can process single samples or batch samples.
