PPE always. ### ⭐⭐⭐⭐⭐ Great *by B***N on July 6, 2026* Great product ### ⭐⭐⭐⭐⭐ After several uses and no material defects upon delivery - it is a win for the consumer *by B***N on January 9, 2021* First things first, if you do decide to purchase this to use with a Buchner funnel you are absolutely going to need adapters or cones for your funnel. If you search "buchner funnel adapters" on here you should be able to find them. Glass arrived with no visible defects. Have used several times with a glorified aquarium pump and Buchner funnel for distillation and making tinctures. Works without issue, but the mouth of the flask is quite large and Buchner funnels tend to run "thin." To remedy this just buy adapters. ## Frequently Bought Together - StonyLab 1000 ml Borosilicate Glass Filtering Flask, Bolt Neck with Tubulation, 1 L (1 Liter) - StonyLab Porcelain Buchner Funnel 120 mm, Porcelain Buchner Filter Funnel OD 12 cm for Laboratory - stonylab Filter Adapter Cones, Premium & Durable Tapered Collar Rubber Stopper Buchner Funnel Flask Cones Adapter Set, Wear-Resisting Smooth Surface, Pack of 9, White --- ## 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.co.za/products/113165323-stonylab-glass-1000ml-heavy-wall-borosilicate-glass-filtering-flask-bolt](https://www.desertcart.co.za/products/113165323-stonylab-glass-1000ml-heavy-wall-borosilicate-glass-filtering-flask-bolt) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-10-01*
