The accelerated flow method for rapid reactions

Abstract A manual syringe drive has been found to fulfil the requirements for a high driving force and a small disturbance to the electro-optical system. A syringe bore has been selected with due regard for the force-speed characteristic of the hand and flow velocities of 25 m./sec. have been obtained in this manner. A direct comparison of a manual and an electric drive has been made and it has been found that the mechanical and electrical effects of the latter upon the photoelectric system greatly reduce the possible range of the electric drive method.
