StonyLab Borosilicate Glass Buchner Filtering Funnel 100 mL with Medium Frit (G2), 56mm Inner-Diameter, 60mm Depth, with 24/40 Standard Taper Inner Joint and Vacuum Serrated Tubulation (100 mL)

I have not left five stars only due to the fact the first item had shown up broken, but was immediately replaced the next day how ever both of the items were not exactly as shown in the description and were both missing the stonylab logo. I contacted the manufacturer and per them this is the only item in the lineup with out the logo which is odd seeing as the image shows the item with said logo. Either way the item is very thick and well made especially for the price

Worked well. Only reason 3 stars is because I wasn't able to find a paper filter that fit. Functioned perfectly other than this.

One of the best Büchner funnels I’ve ever used, glass is thick. Withstood -109f.

Product works great. Good quality overall, however my only issue with it is that it had a lot of debris in it that had to be cleaned before use. Some glass particulate and a lot of what seemed like cardboard fibers. Took me about an hour to wash it out.

If I could give it 0 stars I would, horrible product. Broke under vacuum after the first go.

Nice design works great

Good quality and timely delivery.

Top notch !!

Using this funnel as a secondary filter in making small batch RSO with isopropyl alcohol. Works great with 20 micron filter papers. Backwashing with alcohol after a few batches cleans the frit very well. Well made.

I'm on my second one because I was stupid and knocked the first on off the table. Works great though, no issues so far.

Functions perfectly.

As described. Working flawlessly.
