The Paterson Super System 4 Developing Tanks are simple to load, faster to fill and easier to clean than any other tank. It has a large diameter one piece lid and funnel which clips into place positively and securely, enabling the tank to be filled and emptied quickly.
The Multi-Reel 3 Developing Tank takes three 35mm films or two 120/220 films. The tank comes without any auto-load reels, these are available separately.
The Super System 4 Developing Tanks are designed for the developing of films through agitation of the processing solutions by inversion of the tank using the flexible water tight cap provided, or by rotary agitation using the agitation rod also provided.
300ml of solution is required to develop a single 35mm film and 500ml to develop a single 120/220 film. As a result, developing three 35mm films requires 900ml of solution or 1000ml when developing two 120/220 films.
It is essential that in use, the auto-load film reels are always used fixed onto the centre column that also comes with the tank. This ensures that the tank remains light tight during the processing cycle. The reels are designed to grip the centre column and any number from one reel up to tank maximum can be used. Care should be taken when inverse agitation is used with less than a full load of film and chemistry, as it can leas over vigorous agitation of the chemistry.
