Overview
Not a single flask, this listing is a pack of twelve Pyrex narrow mouth Erlenmeyer flasks with heavy duty rims to reduce chipping. Uniform wall thickness balances mechanical strength with thermal shock resistance.
The reason to buy is the full pack for classroom or lab sets, with durable rims and borosilicate glass. The limitation is a data conflict, as the capacity field and graduation interval describe a larger flask than the title and description.
Who it's for
Teaching labs that need a dozen matching flasks for titration or mixing exercises. Texas orders require a laboratory apparatus permit, and buyers wanting one flask should look at a single-unit listing.
Pros and cons
- Pack of twelve
- Heavy duty rim resists chipping
- Uniform wall thickness
- Round bottom shape
- Capacity fields conflict
- Texas permit required
- Narrow mouth only
Performance notes
The uniform wall gives balanced strength against thermal shock, and the beaded edge limits chipping from repeated handling. Graduation spacing is stated as 25 ml, which is for rough reading only.
