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.

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.

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.

Before TF-4 I used to re-soak the film in the used PMK liquid, but now I can skip that step. Just great.

i started using tf-4 after picking up some pyrocat hd a couple years ago. it quickly became my goto fixer for all film and now i'm using it for printing too.
tf-4 gets the job done consistently and quickly. tap water stop for paper is a nice plus too. my nose isn't the keenest but tf-4 has much less smell than kodafix in my opin.
try it, you won't regret it.

TF-4 saved me from the bad reaction I was getting from acid rapid fixers. I have been using this fixer exclusively for some years now. I pour the gallon concentrate into a large container, mix well and redistribute to four, quart-size containers. One of these at a time is used at 1:4 or 1:6 in my fixer tray for 16x20 printing. No acid stop bath is needed (also allergy causing stuff), just a quick water bath. Also works well with film at 1:4. This is an excellent, long lasting product and Photographer's Formulary ships quickly, is a great company to deal with and definitely deserves its own 5 star review...but that's another story.

I switched from Kodafix to T-4 because I'm developing with Pyro and I wanted to avoid the bleaching associated with hardening (acidic) fixes. T-4 is perfect for that & additionally, works quite quickly to fix my negatives.
Unfortunately, it smells strongly of ammonia. I rather like the smell of Kodafix (acetic acid, i.e., vinegar), but this stuff is nasty. Wear a 3M vapor mask or ventilate well.
One more thing: stock precipitates readily. It's important that you shake the concentrate HARD before mixing your working solution.
(The use of distilled water should greatly help reduce the odor of the TF-4 when it is mixed.) PF
