Description

The perfect container for rehydrating yeast or mixing up additions. Erlenmeyer flasks allow you to swirl your yeast or acid, tannins, nutrients, etc. into solution. The clear glass allows you to see when the solution is fully mixed.

In the lab world, these are known as "Student Grade"

Made from Borosilicate glass, it can be rapidly heated or cooled without the risk of cracking.

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.  Morebeer! 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 kettle 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.  
Features

  • Massive 2L (2000ML) Capacity
  • Made from Borosilicate Glass
  • Fantastic price for a flask of this size
  • Produced for MoreWine!
  • Around 11" tall.

Christopher T on Aug 31, 2022
Has anyone figured out a way to boil wort in this on an electric stove? Description recommends using a boiling water bath, but you will never get the flask to boil vigorously just by putting it into boiling water. Maybe a hot oil bath, but that would be a frightful mess to clean up.
Roy Westerberg on Dec 28, 2019
BEST ANSWER: I have no issues using a water bath with these flasks. The liquid inside gets plenty beyond the temperature needed to sterilize.
Why does this carry a prop 65 warning for lead?
Jonathon E on Dec 7, 2019
BEST ANSWER: Hi Jonathon, from our understanding glass can potentially have a certain percentage of lead due to the content of recycled glass and different feed stocks.

Perfect Tool
This flask is the perfect size and material with which to make a five gallon yeast starter. Convenient to use as the glass can go right on the open flame stove. Quality is excellent.

Erlenmeyer flask works great
I have used this flask twice now to do a yeast starter for homebrewing beer. I have been able to use the flask directly on a stove top burner and directly cool in an ice bath. I also use a stir plate and it works great. There were some other comments that the curved bottom inside the flask prevented the stir bar from staying centered. I have not experienced that; the bar has remained in place and continued to create a nice vortex in the wort.

Works as expected.
I've made a starter with this, on a stir plate, and it worked fine. Looks like it will be easy to clean with a bottle brush.
