Works well but packaging could be better
The bags themselves are excellent, but two arrived folded in a way that made them difficult to unfold without creasing. Functionality is still there though.

Cost saver in the long run
I was skeptical at first, but preventing oxidation means I don't have to mix fresh solution as often. Definitely saves money on chemicals.

Good quality, slightly tricky to fit
The material feels durable and effective. It took me a couple of tries to get the bag seated perfectly in my 15L tank, but once done, it works great.

Essential for large format work
These bags have significantly extended the life of my replenisher solutions. No more skin forming on top of the developer after a week of storage.

No more wasted chemicals
Simple solution to a common problem. The air extraction feature really helps minimize the headspace oxygen. My developer lasts months now.
Q: How do I remove the air effectively before sealing?
A: Gently press the bag down into the container to displace the air upwards, then seal the opening while maintaining pressure. Some users find rolling the top of the bag helpful before final sealing.
Q: Do these fit standard square storage bottles?
A: These are specifically shaped for large format series tanks. For standard square bottles, we offer a different line of anti-oxidation inserts that may suit your needs better.
Q: What is the shelf life of the bags themselves?
A: When stored in their original packaging in a cool, dry place away from UV light, the bags have an indefinite shelf life prior to use.
Q: Can these bags be reused multiple times?
A: While the material is durable, we recommend single-use to ensure maximum protection against oxidation and prevent cross-contamination between chemical batches.
Q: Are these compatible with color film chemicals like C-41?
A: These bags are primarily designed for black and white film development solutions. For color processes requiring strict temperature control and specific chemical stability, please consult the manufacturer's compatibility chart.
