Overview

A teacher or home chemist who needs room for mixing larger batches gets a conical flask with a narrow neck and a thickened rim. It is made of borosilicate glass and stands on a round base.

The conical shape allows swirling without splashing, and the heavy duty rim is there to resist chipping from everyday handling. Missing details are the graduation spacing and what stopper fits the neck.

Who it's for

Teachers, students and hobby chemists working with a litre scale of solution. Quantitative work calls for volumetric glassware, and anyone needing a stopper should check the neck size first.

Pros and cons

Pros
  • Heavy duty rim
  • Conical shape for swirling
  • Narrow mouth limits splashing
Cons
  • Graduation interval unstated
  • Stopper size unstated

Performance notes

A conical body lets a liquid be swirled while the narrow neck holds it in, and borosilicate glass tolerates temperature changes better than ordinary glass. A reinforced rim reduces chipping at the lip, the part that takes most knocks.
