## Questions & Answers

**Q: Hello -- could you tell me the dimensions? Especially height? Thank you.**
A: The flask is 5.5" tall, 3" in diameter at the base, and the neck measures 1.25" in diameter.

**Q: what size rubber stopper does this flask use?**
A: The flask works well with a stopper that has a 27 or 29mm diameter bottom and a 31mm top.  If you are looking for a stopper with a hole in it, Eisco Labs part number CH0314K1H is a good option.  Without a hole part number CH0314L or CH0314K would be sufficient.

**Q: Are thes better than similar ones from cole-parmer (b07b2vct7z) (12 pk for $34)?**
A: There appears to be no discernable difference between the two in form/fit/function with the publically-available info for the CP one. Both are borosilicate 3.3 glass. Ours conforms with the DIN ISO 1773 standard for Erlenmeyer Flasks, likely theres does too.
