Scope of delivery: Set consisting of a magnetic valve with a Mariotte's Bottle, adapter board, connection cable and fitting AC/DC adapter.
The drop dispenser can be controlled by the light barrier system Joker², or drop machine drop-timer².
Using the drop dispenser, pictures of water drops, drop collisions, or other experiments with fluids can be taken easily.
The principle of the Mariotte's bottle ensures a constant water pressure on the magnetic valve, indepent of the liquid level, and therefore a constant drop size all the time.
The water pressure upon the valve is controlled by the position of the lower end of the inner tube: the lower the end, the lower the pressure and vice versa. The pressure remains constant until the liquid level falls below the lower end.
An adapter board connects the magnetic valve, the power adapter and the controlling device. A pushbutton allows the direct operation of the magnetic valve for the purpose of generating drops manually or to refill or empty the bottle.
Important note: Manually generated drops are not defined, their size depends on the length of the keypress.
