Very heavy duty. Have dropped from ~ 3’ on a conc slab and it bounced off with no damage. Really great for teaching, as students are tough on supplies. Best value because they don’t break. All this quality talk is making me want buy some more…. ### ⭐⭐⭐⭐ Good quality beaker *by G***A on January 24, 2025* In general I am satisfied with the purchase. However, one of the beakers arrived broken. This happened with other presentations too and I do not know if it is worth it to return the whole package for just one item. So now I have 3 broken beakers and Amazon does not give you partial returns options... ### ⭐⭐⭐⭐⭐ They really are heavy duty *by A***S on December 24, 2022* The glass is thick, and it doesn’t feel like they are gonna break if you hold them too tightly. I use these as drink cups in my kitchen, and they work well when I want to get a ratio right, or use them as a measuring cup. ## Frequently Bought Together - EISCO 6PK Heavy Duty Beakers, 400ml - 3.2mm Thick, Uniform Walls - Superior Durability & Chemical Resistance - White Graduations - Borosilicate 3.3 Glass - EISCO 6PK Heavy Duty Beakers, 600ml - 5mm Thick, Uniform Walls - Superior Durability & Chemical Resistance - White Graduations - Borosilicate 3.3 Glass --- ## 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.pt/products/267169396-eisco-6pk-heavy-duty-beakers-400ml-3-2mm-thick-uniform](https://www.desertcart.pt/products/267169396-eisco-6pk-heavy-duty-beakers-400ml-3-2mm-thick-uniform) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-24*
