Description
The 5000 mL Erlenmeyer Flask is the ultimate tool for propagating massive yeast counts for high-gravity batches and large-scale homebrewing. Made from laboratory-grade borosilicate glass, it is thermal-shock resistant, allowing you to move it from a flame to an ice bath safely. Its narrow-neck design is ideal for use with stir bars and stir plates, ensuring maximum oxygenation for healthy yeast cell growth. Perfect for 5-10 gallon batches of Imperial Stouts and Belgian Quads.
Brewery Safety Tip: While borosilicate is tough, always inspect for chips or scratches before heating. Use a foam stopper or a piece of sanitized foil to cover the neck during fermentation to allow CO2 to vent while keeping contaminants out. For the best yeast health, use a stir plate to keep the yeast in constant contact with nutrients and oxygen.
