2000ml Erlenmeyer Flask

Build large, healthy yeast starters with the 2000 mL Erlenmeyer Flask, designed for brewers preparing starters for 10-gallon or high-gravity batches. Made from durable borosilicate glass, this flask withstands rapid temperature changes so you can heat wort directly on the stovetop and move it straight into an ice bath without risk of cracking. Its tapered shape encourages smooth swirling, and the flat, stable base works reliably with magnetic stir plates. Borosilicate construction provides excellent resistance to thermal shock, making the flask suitable for boiling, cooling, and long fermentation periods. The 2-liter capacity offers plenty of headspace for vigorous starter activity while maintaining efficient mixing and oxygenation. At 11.25 inches tall with a 6.5-inch base, it fits comfortably in most starter setups, including stir plates and standard kitchen ranges. For best results, sanitize before use and allow room for foam expansion when boiling starter wort. This flask provides
