Major Products/Services

Tosoh Bioscience offers a comprehensive line of TSK-GEL prepacked columns for each of the major chromatography modes, ToyoScreen® process development columns, as well as Toyopearl and TSK-GEL bulk resins for laboratory scale purifications and process chromatography.

Prepacked columns containing TSK-GEL media are designed for the analysis of proteins, peptides, other biopolymers, and low molecular weight compounds. The packings in the columns are either silica-based or polymer-based material, in particle sizes ranging from 2 µm to 20 µm. Columns are available in analytical through preparative sizes, in stainless steel, PEEK®, or glass.

ToyoScreen process development columns are available as an additional tool for convenient scale-up. These are easy-to use, pre-packed columns containing the popular Toyopearl resins and provide a convenient, low-cost method for the evaluation of Toyopearl ligand chemistries.

EcoSEC GPC system is a complete system for the analysis of polymers by GPC. The unit is ideal for semi-micro columns due to its low dead volume and as a result saves time, money, and valuable sample.
