Spinbar Teflon Octagon Magnetic Stirring Bar, 4 Pack, 50mm / 1.96 Inch: desertcart.com: Industrial & Scientific Review: These are awesome stir bars - just make sure you actually have a decent stirring plate! - I won't go and dis any of the models of popular stirring plates out there. I bought one, then ended up buying a set of ten 1" stirring bars to compensate for the inadequacies of the stirring plate I purchased, while at the same time buying another stirring plate for twenty bucks more than the first, and found that the new plate I bought totally rocked while the first one was mediocre. As far as the magnetic stir bars are concerned? Well the new plate works well with any of the stirring bars I have, and now I can use any of my magnetic bars without issue, but these won't perform like you want them to if you get a crummy stirring plate. I really like these, however, and when I want more "bite" in the solution to be stirred, I use these instead of my smaller 1" bars. These are affordable too, which is important. I highly recommend these. Review: Great product - The large size magnetic stir bar certainly has a much stronger vortex and thus the stir power more than other products. Great stuff for a great price.Works better than the other pill shapes I have used. ## Features - Large Size Value Set: Includes 4 pieces of large magnetic stir bars, each measuring 50mm (1.96 inches) in length. This size is ideal for stirring larger volumes of solutions and helps you find the perfect fit for specific containers and liquid viscosities. - Premium PTFE Material: Encased in high-quality PTFE (Teflon) coating, known for its chemical inertness. It resists corrosive chemicals, withstands high temperatures, and offers a non-stick, easy-to-clean surface with excellent insulation properties. - Octagonal Design with Pivot Ring: Features an octagonal shape with a central integral pivot ring. This design minimizes the contact area with the container bottom to reduce friction, ensuring smooth, stable rotation and preventing wobbling during operation. - Versatile Applications: perfectly suited for scientific research in chemistry and biology labs, as well as home use. It is widely used for mixing yeast starters in home brewing, creating tinctures, or blending various solutions. - Durable & High Performance: precise assembly with a strong magnetic core ensures a secure coupling with the magnetic stirrer. These bars are wear-resistant, non-toxic, and designed to generate a strong, consistent stirring vortex. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07YWRCDWP | | Best Sellers Rank | #290,804 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #196 in Lab Stirrers | | Brand | NiceGo | | Brand Name | NiceGo | | Color | White | | Customer Reviews | 4.3 out of 5 stars 162 Reviews | | Manufacturer | NiceGo | | Material | Polytetrafluoroethylene | | Material Type | Polytetrafluoroethylene | | Model Number | 36889889987667 | | Number of Pieces | 4 | | Part Number | 36889889987667 | | Shape | Octagonal | | UPC | 757233489606 | | Unit Count | 4.0 Count | ## Product Details - **Material:** Polytetrafluoroethylene - **Brand:** NiceGo - **Shape:** Octagonal - **Number of Pieces:** 4 - **Manufacturer:** NiceGo ## Images ![Magnetic Stir Bar Large Size, Stirbars/Stir Bars, PTFE Stirrer/Mixer Bar.
