EPRUI Biotech Co.,Ltd. supplies various monodisperse microspheres including polymer microspheres: polystyrene microspheres, PS/DVB microspheres, PMMA microspheres, SiO2 microspheres, monodisperse magnetic beads, fluorescent polystyrene microspheres, dyed microspheres, conductive microspheres…
With precise particle size control technology, EPRUI supplies monodisperse microspheres with narrow particle size distribution. The average CV. is below 3%. Besides, we are able to offer unbeatable price due to large scale production ability. The annual output of monodisperse microspheres reaches hundreds of kilos.
Polystyrene divinylbenzene or PS-DVB microspheres are robust polymer material used as the base framework for most polymer HPLC packing materials. The high degree of cross-linking with divinylbenzene makes the polymer bead extremely durable for high pressure applications including as reverse phase chromatography(RPC) packing resin, ion exchange chromatography column packing resil, Solid phase extraction(SPE) chromatography packings, sulfonated PS/DVB resins for separation and analysis of sugar.
Besides, we can also supply size controllable magnetic beads which are easy to disperse and has good super paramagnetic effect and biocompatibility. By linking different functional groups such as –NH2,–COOH,-OH epoxy groups, etc, magnetic beads can be widely used in the industries of clinical diagnosis, biological imaging, target drug delivery, cell screening, immunoassay, and especially protein, antibody, DNA/RNA/ nucleic acid purification.
