Overview
A teaching lab or small bench with low volume needs gets one narrow mouth Erlenmeyer flask in each of five sizes. They are borosilicate glass with round bottoms, and the carton has partitions to protect each piece.
Getting the full size range in one order saves buying flasks separately. The limit is quantity, as only one of each size is included, and the listing gives no graduation detail.
Who it's for
Low volume users who want the whole size range without buying a full case. Busy labs needing many of the same flask should order cases instead.
Pros and cons
- Five sizes in one order
- Rubber stoppers included
- Partitioned carton for protection
- Only one flask per size
- Graduation details not listed
- Dimensions not listed
Performance notes
The conical shape and narrow neck allow swirling without splashing, and the rubber stoppers close the neck for storage. Borosilicate glass handles temperature changes better than ordinary glass.
