Review on 🧪 Enhanced API Replacement Test Tubes with Caps - Ideal for API Freshwater Master Test Kit - 24 Count Box by Rebecca Jones

Too bad they come in such large quantities but luckily I have lots of testing to do. Not cheap at $0.50 each, but the best unit price I can find. They leak when shaken, which is common with water tests. Not good for shaking harsh chemicals. They break because they're small and glassy, but not quite as fragile as grandma's wine glasses. The caps fit perfectly (except for leaks) and the tubes snap onto the ends. They're OEM, come with 5ml markers, caps and all, but they're a bit pricey. flow too. Honestly, a big twist on API pipes.
