When making working solutions, please note the following:

• If the working solution needs to be stored for a while, it should be stored in an airtight bottle to avoid oxidation.
• Do not mix chemicals with each other to avoid possible toxic gas and heat from being generated.
• Even a very small amount of other processing solution contaminated into the First Developer solution or Color Developer solution can affect the results.
• If any precipitate appears in the concentrated solution, please dip the closed bottle in warm water to resolve any precipitate before use.
• Always prepare water amount first. Then pour Part 1 into water and mix well (about 30 sec.) before mixing with Part 2 (in case of more than 1 part).

8. The working solution can be stored according to the instructions 4 below.

How to make 1,25L of working solutions

1. Stock solution can be measured to make needed working solutions in accordance with the amount of films to be processed.
2. It is possible to processes 20 rolls of films at most with 1,25L of working solutions.
3. The remaining stock solutions can be stored in the original bottles.

How to make 1L of working solutions

1. In case a small amount of film is to be processed, it is possible to make as little working solution as possible.
2. For instance, the chart above shows to make 1L of working solutions to process 16 rolls of film at the most.
3. In case you want to process less film, the amount of water and stock solutions can be calculated accordingly, but please note a certain minimum amount of working solution may be required depending on the processing methods you use.

Processing condition (with 1L of working solution, 135-36exp)

1. Capacity: To ensure repeatable and optimal results of your slide processing, both first developer (R1: FD) and color developer (R3: CD) should be used as one-shot processors for single use only. The minimum filling quantity of the JOBO drum system is about 120 ml per film. This means a maximum of 20 films can be processed with the 2.5 L kit in perfect quality. For one-shot processing the times of 1-4 rolls and 5- 8 rolls apply respectively.
2. Higher capacity may be achieved using the extended capacity times in the table (columns 9-12 and
   13- 16) with the following caveats: If users choose to reuse 1L of chemicals for additional 4 films (totaling 12 films to be processed with 1L), the times setting for 9-12 rolls apply, and the quality of the process will still be quite good. It is possible to use the same 1L working solution to process a total of 16 films, however the process will show less reproducible results in terms of maximum density and color precision. (Here the times for 13-16 rolls of film apply). After processing a maximum of 40 rolls of film, the chemistry will be utterly depleted.

3. The chart above shows the necessary processing condition in case 1L of working solution is used to process films in rotary processing. 4. The processing times change in accordance with the amount of film to be processed in a working solution to be prepared. 5. It may be required to adjust the First Dev (R1: FD) time if a different developing method is being applied. 6. In case of tray processing the films must be processed in complete darkness until the end of Reversal bath processing (R2: RV). 7. The times indicated in the chart include 10 sec of the interval time while draining solutions between the single processing steps. 8. In case failure is found in the color balance, it may be suspected that small amounts of other processing solutions have contaminated into First Dev (R1: FD) or Color Dev (R3: CD). 9. PLEASE NOTE: We strongly recommend to apply the stabilizer bath outside the rotary processor in a separate tray. The stabilizier does not require rotary processsing or other agitation as long as the whole film is being immersed for 1 minute. In case stabilizer comes into contact with drum or reels, these must immediately be thoroughly cleaned with water. The stabilizer should NEVER be poured into the Lift for use in the processor! 10. Prewash allows to adjust film, reels and tank to the critical working temperature required for the color developer. At the same time the prewash will allow for an equal distribution of the developer on the film emulsion. The larger the film format, the more critical it is to use a water prebath.It may be required to adjust the First Dev (R1: FD) time if a different developing method is being applied. 11. The prewash water does not need to be renewed during the whole 3 minutes. During the first and final wash the water should be renewed every 30 to 45 seconds to ensure good and archival proof washing of the film.In case failure is found in the color balance, it may be suspected that small amounts of other processing solutions have contaminated into First Dev (R1: FD) or Color Dev (R3: CD).

Storage condition

1. Once the original bottles have been opened, please store the stock solutions in the original bottles in a dark and cool place.

Disposal

1. Please contact your local government authorities on the appropriate disposal of used or remaining chemistry. Immediately rinse completely emptied chemistry containers while mixing the last kit of chemistry so that plastic bottles can be recycled or re-used.

Safety precautions

1. Keep chemistry out of reach of children. In case chemistry comes into eye contact, please rinse with water. In case of symptoms please contact your doctor.
