Furthermore, it did withstand the boiling mercury which I was slightly worried about. All in all, a worth buy and I would recommend it to anyone who needs a 500mL 3 neck. ## Frequently Bought Together - StonyLab Glass 50ml Heavy Wall 3 Neck Round Bottom Flask RBF, with 24/40 Center and Side Standard Taper Outer Joint – 50ml - StonyLab Thermometer Inlet Adapter with 24/40 Inner Joint, 80mm Height, for Distillation Apparatus - Starfa Lab Glass Hexagonal Head Glass Stopper for 24/40 Joint Glass (2 Packs) --- ## 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.vu/products/61668186-stonylab-borosilicate-glass-3-neck-round-bottom-flask-rbf-24](https://www.desertcart.vu/products/61668186-stonylab-borosilicate-glass-3-neck-round-bottom-flask-rbf-24) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-04-24*
