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 fits our Q34 Foam Stopper. We do not have a rubber stopper that fits this, but the Q34 acts as both a stopper and bacteria filtering airlock.
A gas stove is recommended, as electric burners can cause the glass to crack. Approx. 11" tall.
NOTE: These are general laboratory student grade made in China, and may have small bubbles in the glass or other imperfections that will not affect use.
