About Us

Who we are and what we do

 

Tosoh Bioscience continues to be a leader in the field of bioseparations ever since it was established in 1987 as TosoHaas. In 2000 we became a wholly-owned subsidiary of Tosoh Corporation with sales, marketing, and technical service offices in the U.S., Germany, and Japan. To better reflect the markets we serve, we changed our name to Tosoh Bioscience in 2002. Tosoh Bioscience LLC and our diagnostic sister company, Tosoh Bioscience, Inc., are one of several specialty chemical groups within the Tosoh Corporate family. All instruments, columns and media sold by Tosoh Bioscience LLC are manufactured at Tosoh’s Nanyo complex (4560, Kaisei-cho, Shunan-shi, Yamaguchi 746-8501, Japan). Our Supply Chain facility is located in Grove City, Ohio. All orders are processed and all chromatography and diagnostic products are shipped from this ISO 13485/9001 registered facility.

 

Whether your needs are basic biological research, drug discovery, medicinal chemistry, agriculture, manufacturing, or other industrial applications, Tosoh Bioscience has the optimal solution. Tosoh’s portfolio of over 500 specialty products encompasses all common modes of liquid chromatography and coupled with our expertise, we can help you purify any protein, peptide, enzyme, nucleic acid, antibiotic, or small molecule. We provide bulk chromatographic resins for the purification of biopharmaceutical drugs in commercial manufacturing processes and we manufacture analytical HPLC columns. Our Toyopearl and TSKgel chromatographic resins and columns are renowned for their quality and reliability. The EcoSEC GPC system, an all-in-one GPC instrument for quality control of SEC analyses in organic and aqueous/organic solvents, was introduced at the 2008 Pittsburgh Conference in New Orleans.

 

For over thirty years Tosoh Corporation continues to be the world leader in the analysis and purification of proteins as our TSKgel SW-type columns are the industry standard for size exclusion chromatography of proteins. Our expertise in size exclusion chromatography is based on a fundamental understanding of the role played by pore diameter and molecular size in chromatographic separations. This knowledge, coupled with a thorough understanding of transport phenomena and wide-ranging experience in polymer chemistry and surface modifications, allows us to design higher performance polymeric resins for ion exchange, hydrophobic interaction, affinity and reversed phase applications. Thirty years after introducing the first generation of GPC instruments in Japan, the EcoSEC GPC system is a fully automated 7th generation system, now also available in the Americas.

 

Tosoh Bioscience provides solutions for today’s biological purification needs. We take pride in our ability to design new products based on existing chemistries to solve specific customer applications. We encourage you to have a confidential discussion with us about your specific needs. Whether it is a surface modification of an existing product or the creation of a new one, we encourage you to call on us to discuss your needs for a customized solution.  

 

Whether you need help developing an HPLC assay for the analysis of a new therapeutic target, want to know how to monitor drug metabolites in the human body, or could use support in packing a process development column, our technical support specialists will provide assistance in all of these areas and more. We offer on-site training, application specific seminars, and are the sole sponsor of the HIC/RPC Hydrophobic Bioprocessing Conference.
