Low temperature resistance: good mechanical toughness, even if the temperature dropped to -196 ¡æ, can also maintain a 5% elongation 8.No adhesion: with the smallest surface tension in the solid material, no adhesion to any substance 9.Weather resistance: long-term exposure to the atmosphere, the surface and performance remain unchanged, there is B06B plastic in the best aging life 10.Non-toxic: with physiological inertia, as artificial blood vessels and organs long-term implanted in vivo no adverse reactions ## Features - Size: 7mm * 25mm, Quantity: 10 pcs /bag - Shape: Cylindrical With Ring Shape - Material PTFE (Polytetrafluoroethylene) ; - New & Strong Magnetic, High-quality & Precise sizes - Corrosion resistance,Low / High temperature resistance,High lubrication,Non-toxic,No adhesion,Weather resistance ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | BBTC | | Part number | 43217-32832 | | Item Weight | 33 g | | Product Dimensions | 0.03 x 0.03 x 0.03 cm; 33 g | | Item model number | 43217-32832 | | Size | with Ring:7X25mm | | Colour | pure white | | Material | PTFE (Polytetrafluoroethylene) | | Shape | Cylindrical | | Item Package Quantity | 1 | | Number of Pieces | 10 | | Batteries included? | No | | Batteries Required? | No | ## Product Details - **Material:** PTFE (Polytetrafluoroethylene) - **Brand:** BBTCTY - **Colour:** pure white - **Shape:** Cylindrical - **Number of pieces:** 10 ## Images ![BBTC PTFE Magnetic Stir Bars, 10 Pcs, 7mm x 25mm, Cylindrical, White - Image 1](https://m.media-amazon.com/images/I/91lXDMoU02L.jpg) ![BBTC PTFE Magnetic Stir Bars, 10 Pcs, 7mm x 25mm, Cylindrical, White - Image 2](https://m.media-amazon.com/images/I/81FF8p4hEkL.jpg) ![BBTC PTFE Magnetic Stir Bars, 10 Pcs, 7mm x 25mm, Cylindrical, White - Image 3](https://m.media-amazon.com/images/I/81Rn4AJNBOL.jpg) ![BBTC PTFE Magnetic Stir Bars, 10 Pcs, 7mm x 25mm, Cylindrical, White - Image 4](https://m.media-amazon.com/images/I/715dKK7vGaL.jpg) ![BBTC PTFE Magnetic Stir Bars, 10 Pcs, 7mm x 25mm, Cylindrical, White - Image 5](https://m.media-amazon.com/images/I/811G8EMJ94L.jpg) ## Questions & Answers **Q: Are these strong magnets? i am not sure, as i try to slowly get to max rpm's and it spins out some of the time.** A: Not sure your application on why you need max RPM... I am doing yeast starters for home brew. For me it works perfectly with a 3000ml beaker. With yeast I shouldn’t do max RMP with my stir plate. All I need is slow and steady with a small vortex. ## Frequently Bought Together - Laboratory Magnetic Stir Bars PTFE Magnetic Stirrer Mixer Stir Bars Stiring Rod (Diameter 7mm,Length 25mm) Spinbar Stirring, 10 Pcs - Briess - 812322 - Dry Malt Extract - Golden Light - 1 lb. - INTLLAB Magnetic Stirrer Stainless Steel Magnetic Mixer with stir bar (No Heating) Max Stirring Capacity: 3000ml --- ## 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.ar/products/54776543-bbtc-ptfe-magnetic-stir-bars-10-pcs-7mm-x-25mm](https://www.desertcart.com.ar/products/54776543-bbtc-ptfe-magnetic-stir-bars-10-pcs-7mm-x-25mm) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-22*
