The Tosoh Bioscience customer service center is located in Tessenderlo, Belgium. In Tessenderlo we inventory an extensive line of TSKgel HPLC columns and ToyoScreen process development columns. TOYOPEARL and TSKgel PW bulk resin products are also inventoried at Tessenderlo in quantities suitable for resin screening or early GMP production.
