    • Exactly what I expected
It's a high quality Pyrex flask, not much to say, it's exactly as advertised. Very useful for mixing solutions with my magnetic stirrer plate.

    • Very solid product.
Nice looking. Autoclaveable. Level when on a flat surface. Made in Germany. Very light in hand.

    • Want people to leave your Sriracha alone?
Handy for keeping condiments in the communal fridge. Stuff washes completely out of these and you can easily mark the side. Also, people tend to leave your stuff alone when it’s in lab glass.

    • Exactly what it says.
Bought this to boil off alcohol from tinctures on a hot plate. It didn't explode, so I'm content. It's exactly what you order.

I really loved the design and of course you can’t go wrong with Pyrex glassware, I have used it multiple times and loved its practicality and function.

    • Inexpensive, does the job
Bought this for meadmaking so I could purify(boil) expensive ingredients which might have contaminants before adding them to the must. Works good, but be aware the rubber stopper is airtight. So if you boil stuff in it, then put the rubber stopper on, even if you don't tighten it, the suction created from the cooling air within will suck the stopper in and you will be unable to get it out unless you know reverse sciency stuff. You have been warned about science, unbelievers. ... show more
