A cartridge containing liquid is attached to the holder to pump liquid under pressure, and the system is formed in combination with a dispenser, valve, and liquid drip prevention valve.
The holder is made of stainless steel and has a slit at the bottom so that the remaining amount can be visually confirmed.
After attaching needle adapters (UNA series), tube fittings, dripping prevention valves, etc. to the cartridge, various needles and tubes can be attached and used. There is also an optional holder with a liquid level sensor that shows the remaining amount in the cartridge.
