A good variety of sizes and made a great seal for my amateur Buchner filter set up. Great deal for the price

These are as advertised and work well. I like that the packaging was small and that they arrived quickly. There is a good range of sizes although I really only use 2 of them. I also thought the price was fair. I initially purchased 1 set but my filtering needs increased so I bought another 3. I would recommend.

I have a weird-sized Büchner funnel I could not find the right stopper size to match my Erlenmeyer flask. Then I saw this set of nesting stoppers that let me tailor the precise size I needed. The stopper material is rigid yet pliant and it is very easy to clean. Most importantly, it forms a great vacuum seal when I am filtering with a pump. I am so happy I purchased this.

It's a good product. I would recommend a larger set for same price. These are to thick so a 13 piece set has tighter fitting pieces.

Forms a perfect seal, exactly as desired! I've worked with far too many terrible Buechner funnel adapters in my time, it's nice to own a good one.
