A device is described for aseptically metering liquids at rates as low as 10 ml./hr. The metering rate is constant, but can be readily changed. The device delivers a measured increment of liquid every 10 sec. The volume added is controlled by electrical contants in an electrolyte tube. The medium does not enter this tube.
