Firstcall Chemie Winchester Klarglasflasche - 500ml

Finally, a bottle that doesn't mess with my chemistry—the thick glass feels solid and the inert surface means my fixer stayed clear after three weeks on the shelf. I can leave it half-full without stressing about oxidation, which is exactly what I needed for my small-batch film runs.

The 500ml capacity is perfect for mixing up smaller batches of developer, and I appreciate the inert glass so there's no risk of contamination over time. Cleaning it out between uses has been straightforward with no lingering odors.

The glass feels solid and heavy enough that I trust it won’t react with my developer over months of storage. Pouring from that wide mouth is a breeze, and the 500ml size fits perfectly on my shelf next to the rest of my darkroom gear.
