If you make yeast starters, our heat-resistant glass Erlenmeyer flasks are perfect for preparing the starter solution and growing the yeast. Put the bottle directly on your stove to boil and then cool (with the bottle sealed with a foam stopper) before adding yeast to minimize the chance of infection. Withstands temperatures of over 700 F.
This 2000 ML bottle requires a #9 rubber stopper. Or use our Foam Stoppers (recommended, see link below for correct size) as an airlock to seal while making yeast starters.
A gas stove is recommended, as electric burners can cause the glass to crack. Approx. 11" tall
