room temp RA-4 in trays

[darkroommike]

J-39 is a useful Kodak datasheet:
http://www.kodak.com/global/en/professional/support/techPubs/j39/j39.pdf

It recommends for tubes minimum solution volumes of 110 ml/ft2.

Which works out to 61ml per 8x10.

With respect to trays, it says:

Solution Capacity

You can reuse the chemicals without increasing the time in the developer for subsequent processes. The recommended number of 8 x 10-inch (20.3 x 25.4 cm) prints is 15 per quart (946 mL) or 16 per litre (33.8 fl oz). In some noncritical applications, you may be able to process up to 40 prints. However, do not use developer that has been in an open tray for more than 4 hours.

Matt that link is permanently gone, thank you very much Alaris! But this one is still working http://imaging.kodakalaris.com/sites/prod/files/files/resources/j39.pdf I'd recommend every one download the pdf to your own computer

Hello! I know this is a little old, as 2016 is coming to an end in a few days. But, I would like to ask a question, if you fine people don't mind! I'm thinking about getting Kodak's RA chemicals to experiment with producing color prints. I have read this page many times, and it seems simple enough about the chemistry I HAVE to buy. It seems that in order to process prints at room temperature in trays, one will need the Kodak RA-RT developer and the Bleach-Fix. Well, my question is about the bleach-fix: Does one only need the part 'A' to successfully make a color print. Now, I have looked at the picture of the RA-RT developer on Unique Photo's website. There, is says that you are buying part 'A'. From what I understand, you only need part 'A' to develop paper, right? The photo that is placed on this page of the Bleach-Fix is part 'A'. Is part 'A' all I need of the Bleach-Fix?

You need part A, B, and C for the developer and A and B for the bleach-fix.

Alright. Thank you for the reply. My next question is about the Unique Photo sale listing for the RA-RT developer and bleach-fix. With the product #s that Wayne wrote for the Unique Photo sale listing, does the package come with all parts needed, or JUST part A for the RA-RT and part A for the bleach-fix? The pictures for both just shows part A, but nothing in the text suggests that it comes with the other parts.

8309031 is the same RA4 bleach-fix I use, but it should come in two bottles, parts A and B. I would guess that it does, but you should call them to confirm. Their product descriptions are pretty lacking since this stuff isn't marketed or packaged for darkroom hacks like us. Last time I bought it, it was from B&H, in store. They still have it, but the bottles look different than what I have. I only see the item number in the URL:

Many, many thanks! I have sent Unique Photo a message about what exactly they are selling when it comes to those product #s. Hmm. If Unique Photo doesn't have all of the correct chemistry, and B&H offers it only for pick-up...I'm not sure what to do! It's a long drive to NY from KY, haha. Any ideas about where to order the 10L kits if Unique Photo says they only stock certain parts?

Wait and see what they say. And if you would, please report back. I'm in a position to reorder myself. If they don't carry it, I don't know. Adorama has some options, but it's hard to say what you're going to get.
