The vacuum line connects via Ultra-Torr® fitting to the top left. From the right side, the syringe pierces through a septum (see also picture below). Another Ultra-Torr® connection at the bottom holds the 6mm o.d. glass ampule containing zinc. This setup is specialized for the injection of liquid water with a syringe. Other arrangements are necessary if water is derived from fluid inclusions or from combusted organic matter.
We recommend to inject water at a ratio of 2 microliter of water (= 2 mg) for each 100 mg of Indiana Zinc.
