BTW, we are able to have any film chemical on USA ebay. This is where I recieve all mine.
Yup, iv'e seen it (jealous). However , customs and worldwide shippers aren't very interested in small hazardous packages . Just link, really be thankful. Yay, i have a similar tank as proven at the end!
Btw. Can fixer be reused? I've not seen any notes on fixer expirations or storage, no clue. I can just learn without a doubt that rodinal is instant usage.
Whether it can, how can you tell whether it's expired or lost potency (used). How to proceed for your film out and it is not fixed enough?
Presently i dump it just like i actually do with developer.

And if you're able to find small quantities of the harmful chemicals. This is a recipe that could meet your needs.
Kodak Fixing Bath F-6
Odor free Bath for Films, Plates, and Papers
Water, about 50 Celsius (125° F.) 600 ml
Sodium Thiosulfate (Hypo) 240 g
Sodium Sulfite, desiccated 15 g
* Acetic Acidity, 28% 48 ml
Kodalk 15 g
Potassium Alum 15 g
Cold water to create 1 liter
* To create roughly 28% acetic acidity from glacial acetic acidity, dilute three areas of glacial acetic acidity with eight areas of water.
Dissolve chemicals so as given. To avoid sulfurization, mix the potassium alum individually in a tiny bit of warm water adding this last with rapid stirring.
This bath ought to be used along with an end bath for example Kodak Stop Bath Senate bill-1 or Kodak Stop Bath Senate bill-1a, or perhaps an acidity hardening bath for example Kodak Hardening Bath Senate bill-3 to get the full helpful hardening existence. The hardening existence (capacity) is equivalent to those of Kodak Fixing Bath F-5 provided an acidity stop bath can be used. Having a water rinse the existence is all about one-half those of Kodak Fixing Bath F-5.
Kodak Hardener F-6a
Stock Solution For Preparing Kodak Fixing Bath F-6
Water, about 50 Celsius (125° F.) 600 ml
Sodium Sulfite, desiccated 75. g
* Acetic Acidity, 28% 235. ml
Kodalk 75. g
Potassium Alum 75. g
Cold water to create 1. liter
* To create roughly 28% acetic acidity from glacial acetic acidity, dilute three areas of glacial acetic acidity with eight areas of water.
Dissolve chemicals so as given.
Add one area of the awesome stock hardener solution gradually to 4 areas of awesome 30% hypo solution (2.5 pounds per gallon of solution), while stirring the hypo quickly

From Ansel Adams, The Negative. page 256.
Kodak F-5 (acidity hardening fixer)- Water (125F/52C) 20 fl oz/600 ml
- Sodium thiosulfate (hypo) 8 oz/240 gm
- Sodium sulfite, dessic. .5 oz/15 gm
- Acetic acidity (28%) 1.5 fl oz/48mm
- Boric acidity (very) .25 oz/7.5 gm
- Potassium alum .5 oz/15 gm
- Cold water to create 32 oz/1000 ml
Add an order given. The high temperature will drop quickly because the hypo (sodium thiosulfate) is included the nice and cozy water. When the acidity is added prior to the sulfite is totally dissolved within the hypo solution, the second is going to be irrevocably precipitated.

Fixer could be reused on the limited basis. For small tank growth and development of film, I generally always employ fresh. For photo print paper (after i last did prints), I reused. Damn basically remember fondly the capacity before dumping though!
For expiration. Fixer is rather stable with time, although it does eventually go south. I'd a few jugs on the shelf for over a year so when I finally dumped them, the majority of the sulfur in the thiosulfate had precipitated out and it was coating within the container.
