Tosoh Bioscience serves the pharmaceutical industries, active in research and production of biotechnologically produced pharmaceuticals, research institutes, university laboratories and routine laboratories for biochemical and environmental analysis.

Our Products

Tosoh Bioscience offers a comprehensive line of media and prepacked columns for all common modes of liquid chromatography, including ion exchange, hydrophobic interaction, reversed phase, size exclusion and affinity. The company also offers custom designed resins to meet a variety of separation needs.

TSK-GEL® is available as bulk polymeric resin or in silica or polymeric based prepacked columns. Columns come in microbore analytical through preparative sizes, with particle sizes of column packings ranging from 2 - 20 µm. TSK-GEL® bulk resins are available in 10, 13, 20 and 30 µm particle sizes. Over the last 30 years, TSK-GEL SW columns have become the worldwide industry standard for size exclusion chromatography of biomolecules.

TOYOPEARL® chromatography resins are based on a semirigid, hydrophilic, macroporous backbone and are stable over the pH 2-13 range. Particle sizes are 20 -50 µm superfine grade for the highest performance, 40 - 90 µm for economical purification, and 50 -150 µm for the largest scale chromatography.

Amberchrom™ polymeric resins are high-performance media for reversed-phase, production-scale recovery, concentration, and purification of biomolecules. They are available in particle sizes ranging from 35 -120 µm, with narrow particle size distribution.

Scale-up The similar Chemistries of TOYOPEARL® and TSK-GEL® columns allow seamless scale up. TSK-GEL®, TOYOPEARL® and Amberchrom™ superfine grade (35 µm)polymeric resins are available in prepacked columns for scouting and method development.
