Overview
A lab worker mixing a few hundred milliliters of solution gets a Pyrex Erlenmeyer with a stopper already supplied. The rim is heavy duty to reduce chipping, and an extra large marking space accepts a label.
Uniform wall thickness balances mechanical strength with thermal shock resistance, which suits routine heating work. The scale is approximate, so quantitative work calls for separate measuring ware.
Who it's for
Teaching and general labs for mixing, warming and storage. A volumetric flask suits quantitative preparation better.
Pros and cons
- Heavy duty chip resistant rim
- Rubber stopper included
- Large marking space
- Scale is approximate

- Weight not listed
Performance notes
Even walls help borosilicate glass handle heating and cooling, and the narrow neck allows swirling without splashing. The stopper seals the neck for storage.
