50mm Glass Funnel Short Stem Borosilicate Glass Heavy Wall Karter Scientific 213V10 (2 Pack)

I go these thinking they would be useful for setting up a gas trap. While I have not done that yet I did discover this was a great size for filling my titration burette. They are smallish and seem delicate. However I've managed to drop them a couple times without breaking them.

THESE ARE REALLY GOOD, THEY WORK JUST LIKE A FUNNEL SHOULD WORK....FIRST RATE PRODUCT. I USE THEM TO MIX STUFF...

I am impressed with how thick the glass wall is, and how well constructed. It does not seem fragile at all. This is a quality item. Unfortunately for me, it is too large to fill my #1 capsules. I need a size smaller. But that does not take away from what a quality product this is. I'd highly recommend it to anyone.

I bought this to transfer pollen into small glass vials and it worked well for my needs and was reasonably priced. Packaged well so no damage during shipment. Can't speak to duribility or sturdiness as I really didn't stress them.

VAPING good, solid product, glass thin, but again, not much on the consumer market. guess US makers expect to get rich on everything sold, so prefer the cheaper Chinese
