  • The Exacta Series variable dispense pump is designed for high accuracy and high precision fluid dosing in sensitive applications within analytical, diagnostic, and medical technologies. Full dispense precision of < 0.02% CV on the standard configuration provides unparalleled precision, making it ideal for use in In Vitro Diagnostics (IVD), Sterilization and Laboratory Analytics.

    Variable volumes are achieved by simply commanding different numbers of steps. Controllers may be utilized for microstepping to reach even smaller dispenses.

    Customization of wetted materials, port type, port location and mounting is easily achieved. A rinse chamber option is available for precipitating fluids to increase seal life. An optical encoder is available for added feedback and control.

    Compact choices were made with choice of sensor and geometry of parts easily allow integration into customer designs.
