Loading... Please wait...Formulary's TF-4 Archival Rapid Fixer is excellent for use with PMK and other Pyro Film Developers.. TF-4 is an extraordinary fixer for both paper and some 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 T-Max films, fixing for 6 minutes to remove the magenta stain. We recommend 20 rolls of film to 1 liter working solution. TF-4 does not require a stop bath nor 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 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.

"I LOVE THIS FIX. With salted paper printing, there is no bleaching in the fix, even with extended fix times and mixed at B&W working strength. Plus there is no need for hypo clear so that is a savings of chemistry and tray space.

Love the TF-4, does everything I expect and has never let me down. Only downside is its hugely expensive to ship to Australia :( So I save this formula for my most important films.

This has been a reliable and long lasting fix for me. I use water as my stop and TF-4 doesn’t interfere with any remaining developer in the emulsion. I’ll still use Rapid Fix for tintype but TF-4 is my go to fix for all of my film development. As mentioned by others, it settles out so shake your container of working solution to mix it before using.

I certainly agree. Very impressed so far. The service from PF has always impressed, I just wish you guys had an outlet in Australia to reduce my shipping costs on your products.

I use pyro-based developers on occasion, so I can't use acidic fixers. This keeps well in the bottle. It does require some lead time to dissolve, but distilled water helps to move that along. I have tried other fixers (TF-5) and this fixer seems better at clearing the film. Unlike other fixers, it rinses out fairly quickly, so the fixation + rinse is usually done in about 15 minutes. There is an ammonia smell to it, so I would use it where there is ventilation.

I purchased TF-4 with hopes that it would not bleach out the highlights of lumen prints. Unfortunately, it is exactly comparable to both plain old hypo and Ilford's rapid fixer. I cut test prints in half and fixed them in TF-4 and Ilford's rapid fixer. There is no visual difference between these tests prints.

TF-4 is, without doubt, the finest fixer.....ever! And I'm prepared to pay all the import and export duties, and U.K. delivery expenses, just to get my hands on this stuff.
Well done to all of you at PHOTOGRAPHERS' FORMULARY.

What everyone else has said. The stuff comes in a brown plastic bottle, which I promptly decant into a 1L amber glass bottle upon arrival. It's rather milky-looking, no big deal. After decanting, I mix a liter by adding 250mL of the stock to 750mL of room-temperature, Walmart distilled water, mix thoroughly, then pour into another 1L amber bottle for storage & use. Not being a very active amateur, I develop only a couple 120 rolls of Acros a month, now looking into staining developers. Nice to know TF-4 will suit me. I just stick a piece of masking tape to the working solution bottle and count off about 15 rolls, then discard. Stuff does have a noticeable ammonia odor, but it's not eye-watering; decent ventilation should be fine for all but the most sensitive.Seems to wash out fairly easily, no film paper problems since it came on the market.

This is the best fixer i have used, hands down.
I use TF-4 for film developed in Pyrocat-HD. It does the job, requires no stop, no hypo clear, which saves me money and time.
Easy to mix and long shelf life, plus I get 20 rolls of film to a liter.
FANTASTIC

It is my first acid-free fixer and it is awesome! Ease to dilute, It works faster than my previous "standard" and zero problems with the stain achieved in the Pyro developer. Highly recommended.

When Im printing I want to focus on the creation of the print Fixing on TF-4 cuts time on the two fixing baths, cuts time on washing and allows more time to do what really matters when on the darkroom.
