The ActivaDose® II Iontophoresis Delivery Unit is indicated for the administration of soluble salts or other drugs into the body for medical purposes as an alternative to hypodermic injection in situations when it is advisable to avoid the pain that may accompany needle insertion and drug injection, when it is advisable to minimize the infiltration of carrier fluids, or to avoid the damage caused by needle insertion when tissue is traumatized.

Used by researchers and clinics around the world for tDCS, the Activadose II remains one of the most popular medical and research grade tDCS devices. Originally designed and FDA cleared for Iontophoresis, this device was released with a maximum current setting of 4 mA and maximum output voltage of 80 volts. Featured in numerous scientific publications and advocated by many tDCS professionals the device was quickly adopted by the DIY tDCS community. Caputron exclusively carries a limited edition 2mA / 29 volt version of the Activadose designed specifically for tDCS.

Actvidose II tDCS Device

The ActivaDose® II has two controls to operate dose and current, with optional push-knob or turn capabilities. High-contrast display indicates dose, time and current.
