Overview
Not a volumetric flask, this Pyrex Erlenmeyer carries approximate graduations in durable white enamel and an extra large marking space. Its heavy duty rim reduces chipping, and a rubber stopper is included.
A reinforced rim and even wall thickness suit daily use and heating. The scale is only approximate, so volume must be measured separately for accurate work.
Who it's for
Teaching and general labs doing mixing, heating and storage. Quantitative work needs a volumetric flask.
Pros and cons
- Chip resistant heavy duty rim
- Large marking space
- Rubber stopper included
- Durable white enamel scale
- Scale is approximate
- Stopper size not listed
- Not a measuring flask
Performance notes
Even wall thickness balances mechanical strength and thermal shock resistance, so the glass tolerates heating and cooling. The conical form allows swirling without splashing.
