Paterson 化學攪拌器

That built-in particle crusher saves me so much time breaking up clumps in powder developer. It's the most comfortable stirrer I've used for mixing chemicals in the darkroom.

My hand doesn’t cramp up even after mixing a dozen batches, and that integrated particle crusher at the bottom really helps break up stubborn clumps of powder. It’s got a nice, solid feel that makes stirring feel almost effortless.

That little particle crusher at the bottom works wonders on hard-to-dissolve powder chemicals, and the whole stirrer feels sturdy enough to last through many sessions. I noticed it dissolves my developer much faster than when I used a plain spoon.
