Very robust and the markings are very clear. ### ⭐⭐⭐⭐⭐ good solid flask *by R***D on 3 October 2023* This is very sturdy, good quality glassware and I am confident it will survive for many years of brewing, perfect for making up yeast starters. ### ⭐⭐⭐⭐⭐ Great for making yeast starter *by J***R on 28 December 2023* Arrived well packaged inside a bubble wrap bag and cardboard box. I'm using it with a magnetic stir plate to make yeast starters for my homebrew. Most brewers use a 2l conical flask for their starters but I decided the 1l was sufficient for the styles of beer I brew. Very happy with my purchase so far. Hopefully it will last me many years. --- ## 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.th/products/48465535-borosilicate-3-3-graduated-conical-glass-flask-for-laboratory-500ml](https://www.desertcart.co.th/products/48465535-borosilicate-3-3-graduated-conical-glass-flask-for-laboratory-500ml) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-28*
