كوب بلاستيكي Paterson (تدرجات أونصة ومترية) 1000 مل PTP309

I was pleasantly surprised by the clarity of the metric and ounce markings on the side—makes measuring out film developer batches much more straightforward. The thick polypropylene feels like it can handle years of chemical mixing without cracking or staining.

The graduations are molded right into the plastic, not printed, so they haven't faded a bit after months of developer and fixer. The 1000ml size is perfect for a full litre batch, and the polypropylene shrugs off every chemical I've thrown at it.

Mixing up a litre of developer used to mean juggling two different containers, so having both scales on one beaker is genuinely handy. The polypropylene has taken a few knocks in my darkroom and it hasn't cracked or clouded yet.
