This is not a question but my experience with XTOL. I thought I'd share because someone asks how long XTOL would last and how to store them every now and then here.
This is my experience. Your experience may vary. Tax, tag, and title extra and void where prohibited by law. Always consult professional and don't try this at home. Object may contain nuts. Slippery when wet.
I mixed XTOL with filtered water 8 months ago and stored in my system of bottles as follows:
2 liter
1 liter
1 liter
1/2 liter
1/2 liter
When freshly mixed, 5 liters of resulting solution goes to all bottles. I start using them with smaller bottles first. When both 1/2 liters are empty, 1 liter gets poured into two 1/2 liter bottles. This way, all except the smallest one bottle is always full. They are stored in room temperature and for me, that's 80 to 83 degrees F. I don't do anything else. No saran-wraps, no marbles, no preserver gas, etc.
Last weekend marked 8 months since I started this batch. The results were still fine. I didn't do any scientific comparison study so there may be some loss of activity but then visually, they looked the same.
These bottles are regular plastic brown bottle Adorama sells. Nothing special.
Just to be sure, I did clip test after 6 months period just to make sure XTOL has not gone dead completely. For this, I clip small piece of exposed film, soak in solution for 6 minutes and then fix for 6 minutes. I check to verify the result is a DARK clip, not transparent.
It might gone even longer but my stock is now all empty.
Just sharing....
