Why a Reinforced Beaded Rim Matters
The mouth and rim of a flask see the most handling stress — from inserting stoppers to everyday cleaning. A reinforced thick beaded rim resists chipping better than a plain-finished mouth, extending the working life of the flask under classroom or lab conditions, while the thick-wall body adds resistance to routine knocks. Each capacity is matched to a specific rubber stopper size, so the correct stopper can be ordered alongside the flask without guesswork.
