Wide Neck vs. Narrow Neck Round Bottom Flasks
Compared with a narrow-neck round bottom flask, the wide neck opening on this flask makes it easier to add solids, insert a stirrer or thermometer, or clean the interior between uses — useful wherever the process involves admixture as well as heating. The beaded rim adds resistance to chipping at the mouth, which sees the most handling stress.
