Proveta de plástico Paterson - 11 oz (300 ml) PTP303

The triple scales are a lifesaver in the darkroom—I can mix chemistry without squinting or doing mental math. It's sturdy and the markings are genuinely crisp, plus the 300 ml size handles most of my film dilutions perfectly.

I've been using this graduate for my darkroom chemicals and the three different measurement scales printed on the side make mixing so much simpler. The plastic feels sturdy enough to handle repeated use with developer and stop bath.

Mixing up developer and fixer for my prints used to mean constantly squinting at faded markings, but the widely separated scales on this graduate are readable from across the sink. The metric and US markings on the same cylinder save me from doing mental conversions.
