I purchased the INTLLAB magnetic stirrer, which works very well, and also purchased these bars. I didn't understand at the time that the length needs to be close to the length between the centers of the magnets in the stirrer, but that information isn't provided by the seller. These work a little bit, but only at a very specific slow speed. When the speed was increased, they broke the magnetic bond and rattled around. INTLLAB included a 25mm x 7mm bar that works great up to full speed! It was my fault for not understanding. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars I like these better than shorter ones *by G***S on Reviewed in the United States on March 17, 2020* These mix the liquid faster and with less noise than the shorter bars I've used. Not unbalanced as one reviewer said, it often depends on how centered the bars are on the magnetic stirring plate (particularly home-made plates). ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works well and large enough to stir 4L+ solutions. *by A***R on Reviewed in the United States on November 10, 2019* These work great. I use them in a 5L erlenmeyer flask for making yeast starters (homebrewing). ## Frequently Bought Together - ObtainSurplus 3 Pack, Magnetic Stir Bar - 50mm / 1.96 Inch - Weewooday 8 Pieces 30 mm/ 1.18 Inch PTFE Magnetic Stirrer Mixer Stir Bar ,White Color, Stir Rod Magnetic, Laboratory Bar, Stir Plate Bar,Stir Plate Magnet --- ## 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.com.om/products/92412151-3-pack-50mm-magnetic-stir-bar-pivot-ring-octagonal-shape](https://www.desertcart.com.om/products/92412151-3-pack-50mm-magnetic-stir-bar-pivot-ring-octagonal-shape) --- *Product available on Desertcart Oman* *Store origin: OM* *Last updated: 2026-04-23*
