It is corrosion resistant and has good chemical inertness. It can be used with most chemicals and solvents. (Such as strong acid, strong alkali, water and organic solvent) - HIGH LUBRICATION: PTFE shell helps reduce friction and wear during spinning, the stir bar has the lowest friction coefficient in solid materials. - EASY TO USE: The stir bars are non-sticky, they have the lowest surface tension in solid materials, and do not adhere to any substance. When they are used, they only need to be placed in a container filled with liquid, which is located on a magnetic stirrer. - TEMPERATURE RESISTANCE: This stir bar is resistant to high temperature, the maximum working temperature can reach 250℃; it is also resistant to low temperature, has good mechanical toughness, and can maintain 5% elongation even at -196℃. - WIDE USE: The stir bar is placed inside a container of liquid or solution that is seated on a magnetic stirrer, creating a rotating magnetic field using a rotating magnet or multiple stationary electromagnets. Widely used in biological, chemical, medical and research laboratory applications. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | QWORK | | Part number | WD9196 | | Item Weight | 30 g | | Package Dimensions | 8.4 x 7.8 x 0.9 cm; 30 g | | Item model number | WD9196 | | Size | Type B set of 8 | | Colour | White | | Material | PTFE_(Polytetrafluoroethylene), PE_(Polyethylene), PLA_(Polylactic_Acid), PS_(Polystyrene), Neodymium | | Shape | Cylindrical | | Number of Pieces | 8 | | Batteries included? | No | | Batteries Required? | No | ## Product Details - **Material:** PTFE_(Polytetrafluoroethylene), PE_(Polyethylene), PLA_(Polylactic_Acid), PS_(Polystyrene), Neodymium - **Brand:** QWORK - **Colour:** White - **Shape:** Cylindrical - **Number of pieces:** 8 ## Images ![QWORK® Set of 8 PTFE Magnetic Stirrer, Type B Magnetic Stir Mixer Stir Bar Bars for Laboratory Magnetic Mixer (White) - Image 1](https://m.media-amazon.com/images/I/41ygJXVtVfL.jpg) ![QWORK® Set of 8 PTFE Magnetic Stirrer, Type B Magnetic Stir Mixer Stir Bar Bars for Laboratory Magnetic Mixer (White) - Image 2](https://m.media-amazon.com/images/I/71qWkPc28ML.jpg) ![QWORK® Set of 8 PTFE Magnetic Stirrer, Type B Magnetic Stir Mixer Stir Bar Bars for Laboratory Magnetic Mixer (White) - Image 3](https://m.media-amazon.com/images/I/71FD0rwkUQL.jpg) ![QWORK® Set of 8 PTFE Magnetic Stirrer, Type B Magnetic Stir Mixer Stir Bar Bars for Laboratory Magnetic Mixer (White) - Image 4](https://m.media-amazon.com/images/I/71MhfsAFpEL.jpg) ![QWORK® Set of 8 PTFE Magnetic Stirrer, Type B Magnetic Stir Mixer Stir Bar Bars for Laboratory Magnetic Mixer (White) - Image 5](https://m.media-amazon.com/images/I/71AHrjgFQNL.jpg) --- ## 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/779289300-qwork-set-of-8-ptfe-magnetic-stirrer-type-b-magnetic](https://www.desertcart.tn/products/779289300-qwork-set-of-8-ptfe-magnetic-stirrer-type-b-magnetic) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-08*
