The single neck has a 24/40 standard taper outer joint, and has a 130mm diameter body. Round-bottom flasks provide uniform heating. This flask is made of clear borosilicate glass for durability, chemical- and temperature-resistance, and high mechanical strength under harsh conditions, such as mechanical washing. Borosilicate glass has a low coefficient of thermal expansion and is resistant to thermal stress. The flask meets ASTM International E438, Type 1, Class A specifications for low-expansion borosilicate glass. Boiling flasks are used for heating and boiling liquids, quality testing, sampling, and research, and in lab applications in chemistry, education, research, and life science applications.

It comes down to one feature, as the performance is identical otherwise: Heavy Walls. I'm kinda clumsy, and this thing has already withstood some hair-raising blows with nary a crack. I've also used it for sulfuric acid distillation, which runs at 639°F/337°C using a heating mantle, and it shows no signs of giving up the ghost. ### ⭐ MISLEADING DESCRIPTION!!! Says "3 units" but you only receive ONE UNIT *by K***3 on Reviewed in the United States on 14 January 2019* Description clearly states "3 units" but I only received one flask. The flask is nice, but there are plenty of just as nice flasks for half the price I just paid --- ## 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.tn/products/59894802-chemglass-cg-1506-23-glass-1000ml-heavy-wall-single-neck](https://www.desertcart.tn/products/59894802-chemglass-cg-1506-23-glass-1000ml-heavy-wall-single-neck) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-16*
