Tosoh Corporation

Tosoh Corporation is a large Japanese chemical group with businesses in chlor-alkali, polymers, zirconia and zeolites. Its laboratory side is Tosoh Bioscience, which has two halves. Separation and purification covers TSKgel analytical columns, process chromatography resins and pre-packed columns for biopharmaceutical purification, plus instruments such as the EcoSEC GPC system and the LenS3 multi-angle light scattering detector. Clinical diagnostics covers immunoassay analyzers such as the AIA-2000 and AIA-900. Tosoh Corporation analytical instruments and columns are therefore mostly bought by protein chemists, polymer labs and hospital laboratories.

Sourcing Tosoh Corporation through Xingdaotai Limited

TSKgel columns come in many pore sizes and housings, so send the full part number or the type, dimensions and particle size. We search for analytical columns, process resins in the pack size you need, and spare parts for EcoSEC and AIA instruments. If an item is out of stock, we suggest a comparable size exclusion or ion exchange phase and note the differences.
