PhotoFlow lifetime


So, I got about 3 boxes of darkroom equipment from a friend of my grandmothers. He had some old chemicals in the boxes but it got me thinking, do you think any of these would still work? He said something about using it last around 25 years ago. I'm not sure if that is true or if I heard something in correct. There's some Microdol-X developer in powder form for film in a small pouch to make a quart, not a gallon. It's still sealed, but since I already bought new developer, my question is about the brown glass bottle of Kodak PhotoFlo 200 Solution. It's 1 pint, so does that mean I'll mix it with quite a few parts water still? Anyway, I guess I shouldn't have said that without asking if you think it's still decent to use? I read that you don't want to agitate the photoflo because it can get soapy or bubbly I think it said. Does that mean it's kind of like a soap that will help the water slide off easier? Thanks so much! It's been about a year since I've been on this site and it's been great the whole time. I'm on at least 5 times a day.

  unmixed I think it should still be good. But it's not expensive, buy a new bottle if you want.
Two cap fulls with about a quart of water. It's a water sheeting agent, I think it works like fabric softener. Reduces water spots.

  Wow, just wanted to say that I was washing out the chemical containers (they're empty) and he has labels for what was in the bottles. I think they're liter bottles, and I saw one that says "Dektol 3/24/78" Just making up my own little cartoon with little dried out dektol bugs that haven't seen the light of day for around 27 years haha.

  Another chemistry question...I am going to be mixing my D-76 and was wondering about how I would go about full strength and Dilution 1:1. Now, I think I would understand this if this wasn't a powder chemical, but it is. How does this work? If I just mix it as it says on the pouch, is that 1:1? It says to add 121-131 degree water (3 liters), then stir in and desolve the powder, then fill it up the rest of the way to 3.8 liters. Same as 1 gallon. So if I have a gallon of D-76 that has the powder fully disolved, is that full strength or 1:1 dilution? Thanks!

  1:1 is for liquid to liquid mixing. Make your gallon and that's it. Just follow directions on the bag. Use warm water to dissolve and let it sit over night to cool.
