Foam Stopper for Erlenmeyer Flask
$2.99
This Foam Stopper is for use with an Erlenmeyer Flask or yeast starter. This is the same Foam Stopper included in our Beer Brewing Yeast Starter Kit.
A breathable foam stopper is ideal for use in making a yeast starter in an Erlenmeyer Flask. It can withstand boiling temperatures and helps keep dust out of the flask.
This foam stopper is 1 ¾” diameter, and fits our 1000 mlL and 2000 mL borosilicate glass flasks.
