If you make yeast starters, our heat-resistant glass Erlenmeyer flasks are perfect for preparing the starter solution and growing the yeast. Put the bottle directly on your stove to boil and then cool (with the bottle sealed with a foam stopper) before adding yeast to minimize the chance of infection. Withstands temperatures of over 700 F.

 This 3000 ML bottle requires a #10 rubber stopper.  Or use our Foam Stoppers as an airlock to seal while making yeast starters.

A gas stove is recommended, as electric burners can cause the glass to crack. These are general laboratory grade, and may have small bubbles in the glass or other imperfections that will not affect use.

Large Yeast Starter!
My 2000ml flask needed to be replaced,so I purchased a 3000ml flask. Just the correct size. The price was in line with other online stores and better than a few.
The item was well packed.
I was pleased as for the transit time from coast to coast.

Perfect size for starters
Pros: I looked everywhere for this size flask. 5000ml is just too big and 2000ml doesn't allow for enough head space for a 2000ml starter.  I just add 2000ml water 200 grams of DME, pitch my yeast, and put it on my DIY magnetic stir plate for 18-24 hours. 

Cons: Breakable, so be careful. Bigger than I expected but still fits on my stir plate.

Best yeast starter system EVER!
Pros: Add 1 cup malt to 1500 ml of warm water in a separate pan; dissolve malt, pour into flask.  Install a Williams foam stopper (wet it first).  Boil 15 minutes, cool in a water bath, add yeast and a stir bar and stir on a stir plate for 24 to 48 hours.  Allow to settle, then decant and pitch.  Twice the yeast in half the time, in a completely sterile environment.  The stopper allows air in but keeps spoilage organisms out.  This ROCKS! 

Cons: Well, it's glass, so it's breakable - start heat & cool cycles gently, and handle with care.

After boiling the starter wort in your flasks, can you put them in a cold water bath to cool?
Yes, you can.
