Why choose this product

Engineered for Precision Lab Work

AYINLAB PTFE Magnetic Stir Bars are crafted for demanding laboratory environments. The durable PTFE coating offers superior chemical resistance, crucial for handling diverse solvents and acids without degradation. Unlike generic bars, these are designed for consistent performance across a wide temperature range, from cryogenic conditions to heated reactions. Each bar is precisely sized at 8x30mm with a balanced magnetic core to ensure steady, efficient stirring and homogeneous solutions, minimizing decoupling even in viscous media. Imported directly from authorized US retailers, they represent authentic quality for your critical experiments.

Ideal for Homebrewers & Scientists

These stir bars are perfect for homebrewers needing consistent yeast starters or scientists performing routine lab tests. They are also great for coffee enthusiasts, drink mixers, and agricultural applications. While they offer excellent performance, individuals with extremely high-viscosity fluids or those requiring stir bars specifically designed for overhead mechanical stirrers might find these less suitable. For such specialized needs, consider industrial-grade mechanical agitators.

How to use

  • Prepare Your Vessel — Place the liquid to be stirred into a suitable container, such as a beaker or flask. Ensure the container is clean and compatible with magnetic stirring.
  • Insert the Stir Bar — Carefully drop the AYINLAB PTFE stir bar into the liquid. Position it near the center of the vessel's base for optimal magnetic coupling and steady rotation.
  • Activate the Magnetic Stirrer — Place the vessel onto a compatible magnetic stirrer. Gradually increase the stirrer's speed until the stir bar rotates smoothly and consistently, achieving the desired mixing.
  • Clean After Use — After stirring, carefully remove the stir bar using a stir bar retriever or forceps. Clean it with appropriate lab cleaning agents and dry thoroughly before storing.

FAQ, See What Others Asked

How to choose the right size magnetic stir bar?
Select a stir bar length that is about half to two-thirds the inner diameter of your vessel's bottom. For an 8x30mm bar, it's best suited for beakers or flasks with a base diameter around 40-60mm for optimal stirring without wobbling or losing magnetic coupling.
Are these AYINLAB PTFE stir bars safe for use with solvents and acids?
Yes, the PTFE (Teflon) coating provides excellent chemical resistance to most common solvents and acids used in laboratories, ensuring durability and preventing contamination. They are rated for use between -196°C and 250°C.
What is the best way to use a magnetic stir bar?
Place the stir bar in your liquid within a compatible magnetic stirrer. Ensure the bar is centered and the stirrer speed is gradually increased to achieve steady rotation without splashing or losing magnetic lock. Easy to clean after use.
Can I use these stir bars for homebrewing yeast starters?
Absolutely. These 8x30mm PTFE stir bars are ideal for creating consistent yeast starters for homebrewing, ensuring proper aeration and nutrient distribution for healthy yeast cultures. Their chemical resistance also makes them suitable for other home mixing tasks.
What is the difference between PTFE and Teflon stir bars?
PTFE (Polytetrafluoroethylene) is the chemical name for the material commonly known by the brand name Teflon. So, PTFE stir bars and Teflon stir bars are essentially the same, offering excellent non-stick, chemical-resistant, and high-temperature properties.
How to buy an original AYINLAB PTFE Magnetic Stir Bar set in India?
Purchase original AYINLAB PTFE Magnetic Stir Bars from authorized US retailers and authorized brand partners, imported per-order for you. All customs duties and GST are included in the price, and delivery is via ExpressBox tracked shipping to your Indian pincode.
