The Paterson Chemical Stirrer is an ergonomically designed mixer that is specially shaped for efficient stirring and incorporates a particle crusher.
It is invaluable when making up solutions either from liquid concentrates or from dry powdered chemicals.
This thing works really well but be warned it is a lot bigger than you think it is from the pictures, etc. I thought I’d have to return it because I typically am only mixing 350ml of solution at a time but it works really well even for that amount. Beats the chopstick i was using before!
Paterson products are consistently reliable, so important in the darkroom.
