I bought this to use as a vessel to divide my bioluminescent phytoplankton and prolong the colony’s lifespan. It is perfect for that job! Have also used as a boiling flask and it is a great economical alternative to the Pyrex I usually buy! Was not looking to pay Pyrex prices for a bunch of plankton, but found a very well made alternative! Will definitely buy from again and recommend.

This product is great. I used some extraction methods that require reduction of Grain Alcohol and because the heat displacement is so evenly distributed, it took much less time than other flasks I have used in the past. And, at such a great price with awesome results, I bought 4 smaller ones too.

I was looking for something to display my pretty math rocks in. This ended up being perfect. It's big enough to fit lots of dice including D60s and looks like a large potion vial.
