The Xin Tester® Oval Type A Stirrer Bar is the premier choice for professional research involving round-bottom glassware. With 15 precise size variations and a chemically inert pure PTFE surface, it guarantees stable, high-torque mixing without compromising the purity of your experiments.
Optimize Homogenization for Round Flasks
Standard cylindrical stir bars bounce wildly inside curved glassware. This causes splashing and damages expensive glass vessels. To solve this, chemists need a specialized oval magnetic stirrer bar for safe mixing. The Xin Tester olive design is meticulously crafted. It meets the rigorous demands of advanced chemical research perfectly. It ensures continuous vortex-free stirring for complex liquids safely. Are you setting up a new chemical synthesis station? Please explore our full range of Lab Glassware to build your perfect mixing setup today.
1The Optimized Oval Design
We specifically engineered this tool with a unique olive geometry. Our oval magnetic stirrer bar is heavily optimized for efficient rotation inside round flasks. The smooth shape significantly reduces direct point contact with the glass. As a result, it minimizes friction heavily and prevents the bar from dancing.
2Unmatched Chemical Purity
We encase every magnet in high-grade Polytetrafluoroethylene (PTFE) natively. These stirrers are chemically inert across the entire pH scale. They withstand extremely harsh corrosive environments flawlessly. The pure coating ensures no metallic impurities ever contaminate your delicate work. The mirror-polished finish prevents aggressive reagent adhesion completely.
3High-Strength Alnico Core
Inside each acid-resistant stir bar is a powerful Alnico magnet. It delivers sustained mixing torque through thick viscous liquids. It protects your fragile glassware from deep scratches safely. This powerful core ensures your oval magnetic stirrer bar survives long-duration tasks without degrading or decoupling at high speeds.

FAQs
Why should I choose an Olive (Type A) stirrer bar instead of a cylindrical one?
The PTFE Magnetic Stirrer Bar in Type A (Oval) is specifically engineered for use in round-bottom flasks and containers. Its curved geometry minimizes the point of contact with the vessel floor, which significantly reduces friction and prevents the bar from “jumping” or decoupling at high speeds. It provides much smoother and more stable rotation in curved glassware compared to standard flat-bottom cylindrical bars.
How do I select the correct length and diameter for my laboratory vessel?
A professional rule of thumb is to choose a lab mixer bar length that is approximately 1/2 to 1/3 of the internal diameter of your container’s base. For the thickness (diameter) of the bar, consider the viscosity of your solution: for thicker or more concentrated liquids, a bar with a larger diameter is recommended to provide the higher torque needed for efficient homogenization.
Can these stirrer bars withstand aggressive acids and high temperatures?
Yes, absolutely. Xin Tester® stir bars are encapsulated in high-grade pure PTFE (Polytetrafluoroethylene), which is one of the most chemically inert materials available. They offer exceptional resistance to strong acids, alkalis, and various organic solvents across the entire pH scale. Additionally, they remain stable under high-temperature conditions, making them ideal for use on magnetic hot plate stirrers.
Are these stirring rods non-stick and easy to clean between experiments?
Yes. Due to the self-lubricating and non-stick properties of the mirror-polished PTFE finish, these bars prevent the adhesion of residues or chemical reagents. Cleaning is effortless; most substances can be simply rinsed off with water or laboratory solvents. Their seamless, one-piece construction eliminates crevices, ensuring zero cross-contamination and maintaining the highest hygiene standards for your research.
