It was nice have multiple size options to use. ### ⭐⭐⭐⭐ Clean after every use *by L***L on August 31, 2023* Wide variety of options and keep them clean ### ⭐⭐⭐⭐ Pretty Good Product and Fast Shipping *by J***H on May 19, 2022* This set fits many sizes. I used it to fit a 500ml Buchner into a 1000ml, heavy-walled vacuum flask. The issue I had is the material used in the adapter absorbed some of the filtered material and became discolored. Since I plan on using this setup exclusively for the same material, its not a issue for me but may be for general lab usage. If that's an issue for you, I'd suggest finding a set using a different material. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/345325428-filter-adapter-cones-premium-and-durable-tapered-collar-rubber-stopper](https://www.desertcart.lk/products/345325428-filter-adapter-cones-premium-and-durable-tapered-collar-rubber-stopper) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-04-22*
