Epoxy Magnetic Beads
Epoxy Magnetic Beads are super paramagnetic beads with rich epoxy groups on the surface thus can bind to polypeptides, antibodies and other proteins, oligonucleotides and certain chemical compounds with certain chemical reagent (such as glutaraldehyde). Epoxy magnetic nanoparticles are widely used as an important carrier of the medical and [...]
Carboxyl Magnetic Beads
Carboxyl Magnetic Beads are superparamagnetic beads with high carboxyl content on the surface thus can bind to polypeptides, antibodies or other proteins, oligonucleotides and certain chemical compounds with certain chemical reagent (such as EDC). They are widely used as an important carrier of the medical and molecular biology research [...]
Flow Cytometry Microspheres
Our flow cytometry calibration microspheres have great fluorescence intensity and a wide emission spectrum in multi-channel (FITC, PE, PE-Cy5), which is ideal material used to monitor routine calibration of flow cytometer. Our perfect microsphere counting technology and homogeneous internal dyeing process ensure the test results by the flow cytometer [...]
Dyed Microspheres
Our dyed polystyrene microspheres have vivid colors. The organic color dye is incorporated into the interior of polystyrene latex microspheres, which makes the beads less prone to color bleaching. EPRUI guarantees stable batches and has a variety of specifications to choose from. Colored microspheres are commonly used in lateral [...]

Silica Gel Chromatography
Silica gel chromatography packing is made of monodisperse porous silica microspheres with highly uniform particle size, perfect spherical morphology and optimized pore structure. Our silica gel chromatography media meets the requirements of high performance liquid chromatography (HPLC) analysis in the laboratory and preparative separations in industry scale. The monodisperse [...]
Protein A Affinity Chromatography
Protein A affinity chromatography medium by EPRUI is based on the monodisperse porous poly (methyl methacrylate) (PMMA) microspheres as the matrix, and genetically modified protein A as the ligand, which ensures its high affinity binding of monoclonal antibodies and Fc fragment containing recombinant proteins (macromolecules). Our protein A chromatography [...]
SPE HLB Sorbents
SPE-HLB sorbents are produced with a special polymerization technique. It is corrresponding to Water Oasis HLB or Phenomenex Strata X. They are reverse phase sorbents wettable by water with balanced hydrophilicity and hydrophobicity capable of satisfying most solid phase extrction needs. Monodisperse microspheres in SPE-HLB sorbents are made with outstanding [...]
Anion Exchange Chromatography
SPE-SAX and SPE-WAX are used for the isolation and purification of acidic compounds in basic or neutral medium. Based on a mixed mode of anion ion exchange and hydrophobicity interaction with functional quaternary / tertiary amino groups, SPE-SAX and SPE-WAX can quickly and steadily recover acidic compounds from the [...]
Cation Exchange Chromatography
SPE-HLB sorbents are produced with a special polymerization technique. It is corrresponding to Water Oasis HLB or Phenomenex Strata X. They are reverse phase sorbents wettable by water with balanced hydrophilicity and hydrophobicity capable of satisfying most solid phase extrction needs. Monodisperse microspheres in SPE-HLB sorbents are made with outstanding [...]
