5000ml Erlenmeyer Flask

5000ml flask for making yeast starters. We recommend you tell your customers to use a 3-5 gallon stainless kettle to heat the flask in. Put two inches of water in the kettle and then place the full flask inside the kettle. Softer to heat the flask in this manner, protecting both brewer and stove. Then whole kettle with flask can be brought to the sink and cooled while the flask remains inside the kettle.
