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 Q38 Foam Stopper as an airlock to seal while making yeast starters.

A gas stove is recommended, as electric burners can cause the glass to crack.

NOTE: These are general laboratory student grade made in China, and may have small bubbles in the glass or other imperfections that will not affect use.

Exactly what I ordered.
Perfect size for bigger starters.  Glass seems thick enough that I should never have a problem with it.  There doesn't seem to be any imperfections.  I am happy with this purchase!

Perfect size and well crafted
Glass is thick and seems sturdy. Perfect size for 2000-2500ml spins. Nice flat bottom.

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.

what are the dimensions? should I get the 2000ml stirstarter or the 5000ml stirstarter
This flask is 12" wide, and 17.5" tall. We would recommend the EZ Stir Plate (item R89)  with this large flask.

what is the brand of this flask? Does it have a flat or concave bottom?
These are generic student grade flasks made in China. Their bottoms are slightly concave, although a stir bar can be used with these.

Your foam stopper #10-#11 (Q02) states that it will not fit your flasks. However, I'm wondering if at the time of your foam description entry, you did not have this size flask. Will this foam stopper fit the 3000 mL flask?
For our 3000 Ml Erlenmeyer Flask, item T45, our Q38 Foam Stopper fits best.

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