The Tosoh Bioscience customer service center is located in Tessenderlo, Belgium, where our chromatography products are stocked in a modern warehouse.

Our Customer Service center is open from 9:00AM - 5:15PM, Monday through Thursday and 9:00AM - 4:15PM on Fridays, excluding national holidays (MEZ).

In Tessenderlo we inventory an extensive line of TSK-GEL HPLC columns and ToyoScreen process development columns. Toyopearl and TSK-GEL PW bulk resin products are also inventoried at Tessenderlo in quantities suitable for resin screening or early GMP production.

Larger volumes of our process resins are inventoried at the Tosoh Bioscience manufacturing site in Japan. In many cases, larger customer purchases are made to order. Please be sure to contact us in advance to obtain product availability and pricing for our process resins.

If you are a current customer and need to schedule a plant audit, please contact our technical support group at techsupport.sep@tosoh.com.

Please go to "Ordering information" for more detail on purchasing our products.
