I ordered the wrong size, I needed the next size up but it works!! ### ⭐⭐⭐⭐⭐ I wasn't sure what to expect for the price and am enthusiastically impressed! *by C***E on November 30, 2022* If you are looking for a quality separatory funnel for the price of a mediocre one, Stony Lab wins hands down! The stopper is precision and when turned upside down for a breather, it stays on without holding it. There are clips for this purpose and wouldn't advise it with anything but blue water.Stony Lab has an extensive line of laboratory grade glass and borosilicate extraction, distillation, test tubes, funnels, sieves/filters and flasks. This is a line that I would spend a little money on for an investment. I just ordered the lab stand to go with the separatory funnel.The distributor, J & D Tech, was very professional and was genuinely concerned about my satisfaction with the funnel. I let them know that they will be seeing several more orders for more gear, now that I found a reasonable price for a stellar product! Can't wait to get the stands!Thank you J&D Tech!My reviews aren't always nice and fuzzy but at least they are honest! If you care about the product, then you care about the quality!Chad Okeefe ### ⭐⭐⭐⭐⭐ Well built *by A***R on January 15, 2025* I'll still probably break it ## Frequently Bought Together - StonyLab PTFE Stopcock Separatory Funnel 500ml, Borosilicate Glass Heavy Wall Conical Pear-Shaped Separation Funnel with 24/29 Joint - EISCO Chemical Resistant Steel Ring Stand Set - Lab Stand Support with Clamp - 8 Inch x 5 Inch Base, 24 Inch Rod - Use as Glass Funnel Stand or Test Tube Holder - EISCO CH0688 Labs Clamp Retort, 3 PVC Coated Prongs (Opens to 90mm in Dia.) with Boss Head --- ## 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.com.cy/products/197260071-stonylab-ptfe-stopcock-separatory-funnel-500-ml-borosilicate-glass-heavy](https://www.desertcart.com.cy/products/197260071-stonylab-ptfe-stopcock-separatory-funnel-500-ml-borosilicate-glass-heavy) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-04-24*
