PREPARATION AND DEVELOPMENT TIMES

Stock A+B: When part A is mixed with part B in equal proportions, you will obtain a usable solution that can be reused several times within two months, which is the time during which development is assured. The recommended development time is 8 minutes, with 10 seconds of agitation for each minute.

Dilution 2+1+1: By mixing the stock solution with the same amount of water, a diluted solution of 1:1 (2 parts water, 1 part A and 1 part B) is obtained, which can be used as a single-use solution that must be discarded after use. The recommended development time is 10 minutes, with the solution agitated for 10 seconds for each minute. After the development process, the film must be washed in running water for at least 10 minutes.

• TEMPERATURE: Temperature does not critically affect the development process, but it must remain between 20-25°C.
• DEVELOPMENT: Continuous for the first 30 seconds, 3-4 turns (or 10 seconds) every minute for the remaining development time.
• CAPACITY/DURABILITY: The stock solution can develop up to 15 films in 2 months. However, it is possible that the capacity and durability will be greater. The diluted solution must be disposed of properly after use.
