Hi,
The link provided in “Additional Materials.xlsx” in the schematics and documentation for the peristaltic pumps returns a 404 error (https://www.aliexpress.com/item/10Pcs-lot-For-Aquarium-Lab-Analytical-Water-6V-DC-DIY-Dosing-pump-Peristaltic-Dosing-Head-Free/32649797935.html?spm=2114.search0104.3.60.20ca1d9bu7IqPn&ws_ab_test=searchweb0_0,searchweb201602_2_10065_10130_10068_10890_10547_319_10546_317_10548_10545_106). I could figure out from the URL that it is a 6V motor, but I still do not know which tube size/flow rate I should be looking for.
Thank you!
