Review on 🐠 Gikfun 12V Adjustable Peristaltic Dosing Pump: Precise Liquid Metering for Aquariums, Labs, and Analytical Applications - EK1960 by Tamara Allen

Used to circulate detergent through our ultrasonic scalers. I liked the solid body, the presence of a power supply, a potentiometer with an on / off switch and silent operation. More expensive than a bare pump, but you don't have to solder and dig up the power supply. I can use the corpus if I want to add some dexterity to it in the future. I looked inside and saw that it had a variable power supply (like the LM317) and liked that the box had a water seal around the lid. Very nice, solid design! I highly recommend it if you need something already configured for you with power supply and case.
