Review on 🧪 Plastic Scientific Tube - 90-pack, 13x100mm dimensions by Donnie Boss

I ordered this for a project for my chemistry students. Each group received a sample of liquid collected at the "murder" scene. They then conducted a series of experiments to determine the identity of the unknown liquid and match it to a list of suspects. This set was so cheap that I could afford to give each group their own whistle. I thought they were disposable but the tubes held up well. At the end of the project they were returned and washed. I reckon we'll get another 2-3 years off the set.
