Major Products/Services

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

Prepacked columns containing TSKgel 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, prepacked 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.
