EISCO Buchner Funnel, 9cm - Polypropylene, 2 Parts - Stem Length, 6.5cm - Lightweight, Autoclavable

item as described. looks great. and filters are good too.

This is made well and very durable.

Works as intended and easy to clean

Liquids do not drain out completely. The plastic has some kind of surface tension coating.

It's a fine item, but I think it's too big. You've probably used the 7cm diameter funnel in school, and I think that's the right size. Unless you have a really large filter flask (>500 mL), an above-average strength vacuum (the vacuum has to pull on a larger area, reducing its effect), and a lot of material to filter, I think you should go with the 7cm diameter funnel. VERY important to note: this funnel does NOT go well with 7-8 cm filter paper. The paper is too small. 7 cm paper actually fits the 7cm funnel perfectly. I imagine 9cm paper would fit this one.

Nice item, high-quality definitely worth the money.

great

I can't think of a single reason to buy special "filter paper" for this. I just used coffee filters. Much cheaper and readily available at your local grocery store.
