As many testing tubes that come with test kits are narrow making it hard to see the colour changes, we have 2 different sized testing tubes with broader diameters. With a 5ml marked water line, these testing tubes allow you to swirl as you add the drops while testing and the extra width allows for much denser colours, making any colour changes more obvious, to get better, more accurate test results.
