The 2000 mL Erlenmeyer Flask is a brewery staple for propagating healthy yeast counts. Made from laboratory-grade borosilicate glass, it is thermal-shock resistant, allowing you to boil wort directly in the flask and cool it rapidly in an ice bath. The narrow-neck design is optimized for use with stir bars on magnetic stir plates, ensuring maximum oxygenation to grow a robust yeast colony for your next batch of beer. Sanitary Pro-Tip: Use 200g of DME per 2 liters of water for a perfect 1.040 gravity starter. Cover the mouth with a piece of sanitized aluminum foil rather than an airlock; this allows for gas exchange while preventing wild yeast and fruit flies from entering. Always inspect for chips or cracks before heating on a flame. Show more
