  • Cross rotary mixer

    Cross rotary mixers are used to mix up compounds in powder form in a short time by biaxial rotation.

  • HPLC

    Chemical and optical purity are detected by HPLC.

    Purity criteria is set at high standards at Watanabe Chemical Industries and products with a high level of quality are delivered to our customers.

  • LCMS

    Molecular weight of compounds is confirmed by LCMS.

    LCMS is also used to confirm and identify impurities.

  • Glass reactor

    100L and 50L reactors are used to manufacture acid products.

  • Glass reactor

    Two 300L reactors are used to manufacture compounds such as amino acid derivatives at Kg scales.
