The 5 Best Vacuum Buchner Funnels (2023 reviews)

Compared with other funnel in this category, the eisco vacuum buchner funnel has a design with broader appeal. The medium speed is more than adequate for ordinary filtration tasks. It cleans up well even from coffee residue. The spout on this funnel is about 2cm wide. It's light weight and easy to clean, don't have to worry about it tipping over your flask, unless of course it's filled to the rim with something. The top part is the bowl with the little holes for the liquid, and the bottom part is the funnel that snaps over the bottom of the bowl. It is invaluable for determining recovery weights.

Note that this funnel comes apart for easy cleaning between the funnel and the filter components. They are pricey and slow, if you do this without a vacuum pump, but they work very well.

More sizes and easy to connect to other instruments and connectors
Great value, easy to clean and don't have to worry about breaking it
Easy to clean and works great
