Perfect for yeast starters. Accommodates the No. 7 1/2 rubber stopper. Can be put on open flame. Made from Borosilicate glass, this flask is designed to give the best combinations of thermal shock resistance, physical strength, and resistant to chemical attack. Because it is made from borosilicate glass, you can move it from a boil into a cold water bath for cooling. This means you can do the whole process in one container, keeping it simple and helping to reduce the risk of contamination when transferring from one container to another.

Recommended process for use of flask: Double Boiler Method - It is important for your safety to heat water in the flask with a heat source that distributes heat evenly. Our manufacturer has confirmed that direct heat to the glass can break down its integrity and break if the heat source doesn't distribute evenly. We recommends using the "double boiler method." This process involves using a boiling water bath on the outside of the flask to heat up the water inside the flask. All you need is a stock pot 3 gallons or larger. This process is much safer and efficient. If the flask should break or boil over, your kettle will be there to collect the contents, thus keeping your stove clean and keeping you away from potential harm.
