Drop checkers and solution
Just wanted to get feedback on where everyone gets their drop checkers and the solution for them? Also, I am wondering the price you paid.
Reason I am wondering this is because I have access to a chemistry lab at the university and plan on mixing up 4 dKH and reference solutions for drop checkers for myself. The chemicals that I will be buying for myself will make a couple gallons of this stuff. I have been shopping around for empty plastic bottles, which is the largest cost by far. Depending on where I get the bottles and if I premix the 4dKH or if I would bottle it seperate from the reference solution, I could offer it to others on here for about $2-3 and could ship flat rate for about $5. Depending on the demand, I could offer diy drop checkers and glass bubble counters. Right now, I am thinking I could offer drop checker, bubble counter, and solution for about $20 shipped and possibly less. My thoughts behind all this is that for people building their own regulators, it would be a way to get the drop checker, bubble counter, and solution from one place and pay for shipping once. Right now I am looking for feedback on what people think about the idea and price.
