Safe addition of ethanol to a reflux

[PEROXOR]

Hello, I always ..., when I see clips about chemistry in English, to improve my Chemistry-Englisch for hobby job.

But there are four things, which are unprofessional:

1. You should use a oil or water bath to heat the flask, instead of using a burner.

2. Especialy don't use a burner for heating flamable substances!

3. You should use a two-neck-flask, if you want to add another component to the apparatus, instead of adding threw the cooler.

4. Use a more effective cooler.

Greets from Germany!
