The magnetic stirrer will generate rotational force to drive the substance to rotate quickly. In this way, the substance is completely mixed, and the substance can be concentrated by heating. Multiple uses: Laboratory bar can be applied with various types of magnetic stirrers or heating stirrers. Stir plate magnet is widely applied in scientific research, universities, laboratories in the industrial and agricultural sectors, and is often applied to stir mixed substances.

They’re scientific instruments. Generally, with a few exceptions, there designed to be regularly sterilized. I regularly send mine through a pressure cooker at 15 PSI in liquid cultures **Q: Could these be used with a sensor for an alarm system (Simplisafe)? I have double hung windows so need a slim magnet to put opposite the sensor. Thx** A: Probably, but I suspect it would be much easier to use one of these that's the size you want: https://www.amazon.com/s?k=neodymium+disc+magnets&crid=3RBE9SKKGYW9W&sprefix=Neodyn%2Caps%2C235&ref=nb_sb_ss_ts-doa-p_5_6 **Q: is there any possibilities that these could degrade and leak into the water? any easy way to see it? thanks** A: There is nothing to leak. Inside is a solid magnet. It's possible that after using them a long time, friction could wear out the plastic coating, but that will probably take years and you'll see it slowly degrading. Just take a quick glance before you use them and if they look like they are in good condition, they are. **Q: Is there a "flat" side of the magnet, or are both sides curved?** A: Both sides are curved. ## Frequently Bought Together - Weewooday 8 Pieces PTFE Magnetic Mixer Stirrer Bar, White Color Stainless Steel Laboratory PTFE Stir Plate Bar, Mixing Plate Magnet Stick (30 mm/ 1.18 Inch) - INTLLAB Magnetic Stirrer Stainless Steel Magnetic Mixer with stir bar (No Heating) Max Stirring Capacity: 3000ml - 50ml Beaker, Low Form Griffin, Borosilicate 3.3 Glass, Double Scale, Graduated, Karter Scientific 213D31 (Single) --- ## 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/439037617-ptfe-magnetic-stirrer-mixer-stir-bar-white-color-stir-rod](https://www.desertcart.tn/products/439037617-ptfe-magnetic-stirrer-mixer-stir-bar-white-color-stir-rod) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-11-14*
