Frits & Empty Cartridges/Plates For Solid Phase Extraction (SPE) 、Solid Phase Support Liquid Extraction (SLE) are made of ultra-high molecular weight polyethylene powder (UHMWPE) with a certain particle size through a special sintering process. The products have excellent chemical resistance, organic resistance and biological inertness, with specific porosity and super hydrophobicity, which can ensure the purity of the frits, good permeability and stable reagent permeability, and then it is widely used in the application of sample pretreatment of Frits & Empty Cartridges/Plates For Solid Phase Extraction (SPE) and Solid Phase Support Liquid Extraction (SLE).

Frits & Empty Cartridges/Plates For Solid Phase Extraction (SPE) 、Solid Phase Support Liquid Extraction (SLE) and affinity chromatography are made of medical grade polypropylene by one-time injection molding. Common specifications are 1ml, 2ml, 3ml, 5ml, 6ml, 12ml, 20ml, 30ml, 60ml, 300ml empty Cartridges, 1ml, 1.5ml, 2.3ml 96-well plate, 80ul, 300ul 384-well plate, etc. These empty cartridges and well plates, matching frits and functional packings are widely used in the whole process of sample pre-processing such as compound solid phase extraction, target sample filtration, adsorption, separation, extraction, purification and concentration.
