Reddit reviews Flask, ERLENMEYER NARROW MOUTH ~ PYREX GLASS 2L

Amazon has really good customer service, just ask for your money back, and you will get it. I once was sold fake Wusthof by one of their 3rd party shops and was pretty upset seeing how I paid north of $400 for them. They refunded the money right away, gave me a gift card for my troubles, and paid for shipping. It took all of 10 minutes to get my money back.

There are Many different types of products on Amazon; Made and sold by Amazon, fulfilled by Amazon by their Prime service, and sold on Amazon. The last option for example ( http://www.amazon.com/gp/product/B001BLKL4W/ ) is on Amazon but sold and shipped by "Ships from and sold by Scientific Strategies." Amazon tries to control when these 3rd party companies pull fast ones, but it can happen. A lot of times, these companies will get black-listed for doing what they did to you. It sucks you got a shitty product, Amazon's should take care of you, no questions asked.

Like /u/suburbdad I weigh the DME in the flask, drop in the stir bar, then add tap water to volume in my 2L Erlenmeyer flask (German Pyrex). Adding the water that way gives me the chance to rinse the sticky DME that always falls to the wrong place!

I then put the flask directly on the gas stove and bring it to a boil. This process sanitizes everything involved and even does a quick hot break on the DME.

From there it goes into a bowl of ice in the kitchen sink (with sanitized foil on top) where it sits and melts the ice.

20 minutes later it's ready to spin with yeast.

It's an Erlenmeyer flask. Here is one on amazon.

You want lab grade borosilicate.
