Related Questions and Answers

Q: 1. Will this harm the bath?

A: Not at all.

Q: 2. The bottle says dilute 1:41 and the info on the product information online here says dilute 1:43. Which is correct?

A: According to the manufacturers website it is 1:43.

Q: 3. How long is it safe to store an opened bottle after squeezing out the air?

A: It is safe to store the Arista Film Developer Liquid (12 oz) in that state for 6 months.

Q: 4. How many rolls of 35mm can each bottle develop?

A: The following makes a 1 gallon develop fix which will accommodate 10-13 rolls of film.

Q: 5. How many rolls of 35mm should I be able to fix with this at the working dilution?

A: The Legacy Pro Liquid Fixer Solution (32 oz) is estimated to last about 24 rolls of 35mm film.

Q: 6. Can I mix and make the full 13 gallona at once -then use it as one shot for 6 months?

A: You can mix Arista Premium Liquid Film Developer (5L) to make 13.2 gallons and use it for six months as long as the solution is stored in a dark bottle that is sealed tightly.

Q: 7. How long does a partly used bottle last on shelf at 68 degrees?

A: A partly used Arista Liquid Paper Developer needs to be stored in a bottle with no air. The bigger the area with air, the faster the developer will oxidize and not work anymore. A half bottle would last about three weeks. As the developer turns orange brown it loses its effectiveness.

Q: 8. Can you use this to check stop bath?

A: No, Arista Premium Hypo Check is only for checking your fixer chemistry. It helps you determine if the fixer is exhausted.

Q: 9. What are the consequences of using a non-hardening fixer for RC paper?

A: RC papers can use either hardening or non-hardening fixers. A non-hardening fixer, such as the Arista Premium Odorless Liquid Fixer (32 oz), is only needed when using a fiber-based paper that you plan to tone.

Q: 10. Is there a shelf life for the Eco Pro concentrate prior to mixing?

A: Unopened eco•pro Neutral Fixer and eco•pro Hypo Wash bottles should be kept in cool, dark conditions. The products have a virtually indefinite shelf life. Once opened, the concentrate should be kept in tightly closed glass, PET(PETE) or HDPE containers, and used within twelve months. For best results in small scale darkrooms, a large opened bottle should be divided into several small glass or polyethylene bottles filled to the top to minimize exposure to air. eco•pro Hypo Wash concentrate may form white crystals if it is stored in contact with air. If a significant amount of crystal forms, discard the solution and replace it with fresh stock. It is inadvisable to use eco•pro Hypo Wash which has crystallized, as the accelerated washing function is impaired even if the crystal is dissolved after dilution. eco•pro Neutral Fixer and eco•pro Hypo Wash working solution may be stored before and between uses, in a tightly closed glass, PET (PETE) or HDPE containers. Discard eco•pro Neutral Fixer when the processing capacity is reached. The processing capacity of eco•pro Neutral Fixer depends on the processing sequence being used. Processing capacity is indicated in the "Summary of recommended sequences" section for archival standards. Each liter of eco•pro Hypo Wash working solution (1+19) can process more than 50 8x10 prints. Discard eco•pro Hypo Wash working solution when capacity is reached, or it is stored for more than two weeks, to ensure archival washing quality. The archival processing capacity of eco•pro Neutral Fixer is much greater when the subsequent washing procedure incorporates treatment in eco•pro Hypo Wash. This is because the archival processing capacity is limited due to more fixing reaction byproducts formed in partially exhausted fixer. The byproducts are more difficult to wash out than the fixer itself, particularly from fiber based papers. The use of eco•pro Hypo Wash promotes the efficient removal of both fixer and fixing reaction byproducts from all photographic materials, thus increasing processing capacity of the fixer. eco•pro Neutral Fixer (concentrate) is a clear solution free of insoluble sediments. eco•pro Hypo Wash (concentrate) is a clear solution free of insoluble sediments, but it will develop white crystals if the solution is stored in contact with air (oxygen) for a prolonged period of time. When more than a few small crystals are formed, discard the solution.
