The bottom is rounded, which means it will not sit flat on a table, and thus requires a distillation stand. The flask also features a tooled lip. Stopper size for the flask is No. 6. Excellent for chemical experiments and lab exercises in the classroom setting, or for demonstration purposes for a science fair project.
