Let me see if I understand this. You want to repeatedly fill bottles with a measured amount of a liquid. You want highly repeatable accuracy. One way would be to use a piston injector with a calibrated volume equal to your desired amount. As an example, check out the following: Oil-Rite new product I have no experience with the above referenced vendor, but provide this as an example. Another would be to use a small positive displacement flowmeter; then count off the pulses, closing a solenoid valve on target reached. You might try finding an on-line packaging or medical equipment magazine, and posting requests for more information there.
