Glass Filtering Flask with Upper Tubulation, 1000ml (Single)

The glass is very thick, and I'm a big fan of the demarcations along the side. Please note, though, that the stem for attaching to a vacuum line is larger than you might be used to. In the attached photo, the flask on the left is one I already own that fits pretty much all the tubing I've ever worked with, and the flask on the right is the one in this listing. I can force my rigid tubing over it a little, so it works out, but just be aware. Yes, I know that the listing itself gives dimensions of the stem.

Excelente cumplimiento, calidad y empaque

I like that these are sturdy and easily clean up after using chemicals in them for gold reclamation.

This has increased my productivity 4 fold. I purchased this an=d the 800ml Buchner funnel.

Love the durability of this flask and it was a great price

Very Poor Quality first unit came broken second unit had a bubble in the glass Had too send two units back for refund in full. Don't waist your time. Update: 2/24/2020 I ordered the same size Filter Flask from a different manufacture WOW what a difference in quality a Stone makes the glass is twice as thick and clear no problems.

High quality product

2 of the 4 were smashed to pieces in the box. No bubblewrap was used, only paper. Still, not the worst price on 2. Overall was disappointed with the packaging, not the flasks.
