Concentrate filling system includes a solid loader operable to dispense particles through a dispensing end. The system includes a conveyer operable to receive the dispensed particles at a proximal end and further dispense particles at a distal end. The system includes load cell operable to receive a container that receives the dispensed particles. The system includes an injection pump to dispense fluids into the container. The system includes controller operable to receive data from the load cell indicative of a weight of the particles and/or fluid and send a control signal to the conveyor to adjust the dispensing of the particles and send a control signal to the injection pump. Upon receiving indicative of a predetermined weight of the container, fluid, and particles, the controller is operable to send a control signal to the conveyor and the injection pump to stop dispensing of particles and fluid.

Aspects of the disclosure are directed to weighing apparatuses, autonomous materials synthesis systems and methods, as well as their implementation. As may be implemented in accordance with one or more embodiments, a galvanic actuator includes a disk disposed between magnetic poles, and a coil coupled to the disk. A weighing arm is coupled to the disk and includes first and second ends respectively extending away from the disk in opposing directions, the first end having a pan to hold material, the second end having a counterweight. A controller circuit applies voltage to the magnetic poles to generate a magnetic field that applies torque to the disk, countering torque applied to the disk via the material in the pan. Processing circuitry generates an output indicative of weight of the material, based on the voltage applied by the controller circuit for countering the torque.
