I always find it challenging to mix up small quantities of the 1:200 dilution prescribed for Kodak Photo-flo (the standard stuff - not the extra concentrated 1:600 stuff that labs use). If I'm trying to mix up 300 ml of working solution, I don't have a good way of accurately and repeatably and cheaply and easily measuring the necessary 1.5 ml of the concentrate. And I'm reluctant to solve the measurement challenge by mixing up larger quantities of working solution and keeping the unused...
...cheaply and easily measuring the necessary 1.5 ml ...
1.5ml is a common measure in some settings, so special syringes with a stop at 1.5ml are also available for pennies.

Great idea. Really great idea. PhotoFlo gunks up plastic reels. It's a great product, most people that have problems with PF are simply using too much. 70% isopropyl is available at Walmart for a couple bucks.
I always use RO water and just a wee bit of PhotoFlo. I leave the film on the reels when I use the final rinse on all processes. I'm so fumble fingered at times. I am afraid of scratches or some other catastrophic incident. I learned as a kid not to use a freaking squeegee. If I need new reels I will buy them. I don't have a problem, but I use very little surfactant. I have some awesome Pako film clips, I air dry my film. Wash the reeks off in hot water when through.I remove the film from the reels and drums and put them in a plastic container with the diluted PhotoFlo. That keeps the reels and drums from getting gunked up.

I picked up a beautiful film dryer cabinet from my wonderful photo shop that closed. It works well, but mostly I've used it when processing a lot of film with friends.
I only dunk one reel at a time in a separate tank.
I like the idea of dilution with alcohol. What I might do is just dilute it to 30 or 50% and use a medicine dropper.
I know and I categorically don't give a hoot in hell what Jobo says about surfactant. The most important thing about loading a Jobo reel is trimming the leading corners of the film you are loading. I use a 3 or 5 mm corner rounder. I don't have ANY trouble loading the reels. I just push the film on slicker than snot on a door knob.Jobo categorically states not to use PhotoFlo on its reels and drums. When the film is wet and your hands are wet, you will not scratch the film when removing film from reels or drums.
