Photographers' Formulary TF-4 Overview

Photographers Formulary TF-4 Archival Rapid Fixer is an extraordinary fixer for both paper and most films.

TF-4 works well in batch processing, fixing resin coated paper in 30 seconds and fiber based paper in 60 seconds.

You can also use TF-4 on TMax films, fixing for 6 minutes to remove the magenta stain. it is recommended to run 20 rolls of film to 1 liter working solution.

TF-4 fixer does not require a stop bath or a hypo-clearing agent, and has little odor when mixed with distilled water.

TF-4 is a non-hardening fixer, which makes it excellent for prints that are to be toned or retouched. Most modern film emulsions have a built-in hardener, eliminating the need for hardener in the fix.

The stock solution which has a shelf life of 1 year is diluted 1:3 to make the working solution. The working solution has a shelf life of 6 months.

TF-4 is recommended in The Book of Pyro for PMK negatives, by Gordon Hutchings, due to the fact that an alkaline fixer solution such as TF-4 helps achieve maximum pyro stain on a negative.

A conventional rapid fix may diminish staining effects of pyro and PMK formula.

This will make 1 gallon of Working Solution.

How long does this last after you open it or mix it. I read that its 1 week. while others last 3 months?
Asked by: Reuben
I mix one gallon and it keeps for months on end. Since I don’t print every month I just store the used portion in a separate container and test it with Hypo Check before re using it. H

I purchased this product about 4 years ago and never opened it. Would it still be good to mix and use today?
Asked by: Edward
If one purchased the Photographers' Formulary TF-4 Archival Rapid Fixer for Black & White Film & Paper ,and never opened it up, and stored it in normal temperatures,(not too warm), it should still work fine. Just to make sure it would be good to do a test in the darkroom, by fixing a paper sample for the normal fixing time, and then turn the lights on to see if it will fog.

How to I dispose of the working solution?
Asked by: Anonymous
Although it is best to take photo chemicals to a facility where they can be properly disposed of, most normal chemicals used in processing are no worse than household cleaners that are normally put down our drains. (Bleach, 409, etc.) So use reason and common sense: if you process 200 rolls at a time, dispose of the chemicals properly. If you are doing 3-4 rolls every week or so, you shouldn't worry and pouring them down the sink is fine.

I today received 1L of this fixer from B & Xbut instead of experiencing joy, I am greatly distressed.At the bottom of the bottle there is a lot of sediment, which is impossible to dissolve.Is this a non-suitable solution?Can I use this solution for my film?
Asked by: Viktor M.
I agree with Bob S, since you have to dilute it in water using as measurement, I poured the concentrated solution in a gallon container then, filled only half way the original bottle gave it a good shake then, filled the whole water and shake again then poured it into the gallon jug and repeated it until all dissolved and I got all the solution in the jug. I just used tap water.

After manifestation in PMK and fixation and washing for 25 minutes, the Tri-x 400 film turned out to be slightly brown. This is normal?
Asked by: Viktor M.
Indeed that is typical. Depending on the color of the stain, negatives developed in PMK can be hard to print on variable contrast papers. Also, if the film had a purplish appearance after fixing and before washing, that purple color should wash out easily.

Not so much a question as a bit of information, I saw in reviews that some one had said to mix this 1 part chem to 3 parts water this is not correct. It seems be misleading and 1:3 actually represents the fraction 1/3 a whole of 3 parts with 1 part chem and 2 parts water. Just wanted to clarify this to all.
Asked by: Jeremy
This is where photography deviates from actual laboratory work. Photography = 1:3 means 1 part solution + 3 parts water (4 parts total), this is what you should use for the fixer. Whereas in a lab, and I have 20+ years in biotech...Lab = 1:3 means 1 part solution (in 3 total parts) + 2 parts water (total volume - solution or 3-1=2)

How can I test my T4 fixer to see if it is exhausted?Can I use my old test solution I used for regular fix?
Asked by: Anonymous
Put a small amount of the working solution (fixer), into a beaker along with an inch long film leader that has not been used/developed and mix the two together. The film leader should turn CLEAR in about 30-45 secs.

Hi, if I'm processing two rolls of 35mm films at a time, Is it better to prepare 500ml of this (125 ml fixer to 375 ml water) each time? Or to mix the whole bottle into a gallon at the beginning? In the latter case, would I pour the used content back into the gallon bottle after I'm done? Or do I discard it? Do I need to keep the gallon bottle full if I discard the used content? Thank you!
Asked by: Shasha L.
Since the fixer is reusable you can prepare the entire thing which yields one gallon and each time you finish you can just pour it back into the jug. Keep using it until it is no longer effective and then discard it properly.
