Graphene Oxide (GO)

    Graphene oxide is a critical intermediate in the production of graphene, used in lithium batteries, sensors, transistors, and display technologies. Its production requires the oxidation of graphite, followed by multiple separation and washing stages to remove harsh oxidizing agents such as sulfuric acid, permanganate, or nitrates. Traditionally performed in lab-scale centrifuges, these steps can be time-consuming and difficult to scale. JOECHRE filtration systems offer a fully enclosed, automated alternative capable of handling larger volumes with consistent quality. Our filters support multi-stage washing cycles to lower conductivity and residual metal content, with corrosion-resistant internals to withstand aggressive chemistries. The result is a cleaner, scalable, and more efficient process for high-purity GO production.​
