Jobo 9510 Alpha B&W Kit (Film Developer + Fixer)
Jobo 9511 Alpha B&W Film Developer - (2x300ml)
The Jobo 9511 Alpha B&W Film Developer has been co-engineered with German chemist Klaus Wehner. It is based on the original formula of Agfa Atomal which is different than the Adox version that is currently available.
The Jobo Alpha B&W Film Developer allows full use of the film speed and is still characterized by very fine grain structure and great sharpness. It has been specifically designed for rotary processing of any type of black-and-white negative film. Of course it can also be used for inversion processing, but in rotary processing it truly excels.
To ensure the developer's shelf life, it is supplied in two parts of 300ml and has to be mixed and diluted with only water. Both bottles deliver a total working solution of 6L which allows to develop to about 50 films.
It is important that the developer is used in combination with a ph-neutral fixer (natrium thiosulfate). This is the most gentle way of processing the organic film emulsion. For this, Jobo has also released the accompanying 9512 ph-neutral fixer in powder form which is available separately or in a complete kit with the Alpha film developer.
Jobo 9512 Neutral Fixer - (3x2L)
The Jobo 9512 Neutral Fixer is a sodium thiosulphate based pH neutral fixer for all types of black-and-white negative films. The fixers comes in powder form which ensures a high shelf life. It comes in three separate bags. Each bag lets you make a working solution of 2L. As such the kit allows you to make 6 liter of fixer.
Please note this fixer cannot be used in combination with classic stop baths like citric acid stop baths. Instead, a short water bath has to be used in order to stop the development proces prior to using this fixer.
The fixer is odourless and free of harmful emissions. It is ideal for rotary developing processes and is designed to be used with the Alpha B&W Film Developer from Jobo.
