Paterson Plastic Graduate - 22oz (600ml) PTP304

The markings on this graduate are spaced so clearly that I don't have to squint to measure chemicals anymore, and the cylindrical shape makes pouring much cleaner than my old square beakers. It’s sturdy enough to survive a few drops in the darkroom too.

Finally, a graduate that’s actually easy to read in the dim darkroom light—those three separate scales (metric, imperial, US) are spaced far apart so I don’t have to squint. It pours neatly without dripping, and the 600ml size is perfect for mixing up a single batch of print developer.

I use this for mixing chemistry in the darkroom, and the dual metric and imperial scales save me from constant conversions. The markings are spaced far enough apart that I can read them even under safelight.
