TOKU-E is a research chemical manufacturer that cares about the needs of scientists. We produce small batches of ultra pure antibiotics specifically for scientific research applications such as cell culture, molecular, microbiology and plan biology.

EvoPure® is a product line developed by the TOKU-E R&D team which employs proprietary chemical separation methods to produce highly purified, single antimicrobial congeners, metabolites, and impurities, most >99% pure. The composition of most USP and EP pharmaceutical products is generally not limited to a single compound, but rather, a mixture containing one or two major compounds and other congeners (related compounds and impurities).
