this glass is verrrrry THIN! Only after a few uses the glass randomly broke on me - if you can see the picture. I don't know how to contact the seller about this but i'm just going to return it. I DON'T recommend this Separatory Funnel.

The funnel itself seems perfect, however mine did not come with the stopper shown in the picture, rending it temporarily useless unless I feel like riskily betting I can make a good seal with my fingers through a pair of gloves as I shake it. Incidentally, it took much longer to come than advertised, but I don't mind that. Had it come as pictured, a fully functional unit thanks to a cap, I'd give it 5/5 stars, no doubt. I'll make due, and hopefully be able to buy a top myself with the $4 I got by calling Amazon.

Worked well until the side blew out under minor pressure. Only used a few times and not abused. Stick to the name american brands.

The valve is a little tough to turn, but it does what it needs to do

Totally unusable. Acetone ate the plastic immediately. Very cheap!
