The following three transport ways, using materials inactive photochemicaly were tested. Then attention was paid, to keep the discharging quantity constant regardless of the variation of input pressure, and to ensure the possibility of small quantity transport.
1. Gear pump.
2. Flow down system controlling discharging quantity by overflowing.
3. Plunger pump with ball valve.
Gear pump was available for liquid, containing gelatin, but not for silver nitrate solution. On the other hand, flow down system was suitable for silver nitrate solution but not for liquid containing gelatin.
Plunger pump with ball valve was availabe for any liquid. The discharging quantity was kept constant precisely. The discharging pressure was big and proportional feeding for several liquid was possible.
