The MDS-1 one-axis motorized micromanipulator is add-on type for Z-axis direction that is suitable for experiments in rodents. Ideal for precise control that requires careful work in mouse/rat brains, such as implanting GRIN lens, inserting optical fiber and silicon probe for multi-neuron recordings. The drive unit is controlled digitally and remotely that offers speed control and precise control: those operations are impossible to be performed by manual model. Two setting modes are available: entering speed directly or entering distance and time. The range of drive speed is set as 0.1µm/s to 500µm/s. The drive unit accommodates to hold a shaft with 3mm to 8mm O.D.
