Description
Product Overview
The Microyn 4 piece PTFE stir bar set is engineered for demanding mixing tasks across laboratory, industrial, and home research environments. Each set includes two cross‑type bars measuring 38 mm in length and two straight‑type bars measuring 50 mm, providing a balanced combination of stability and reach. The core of each bar is a high‑grade NdFeB magnet that delivers a powerful magnetic field, ensuring rapid and consistent rotation when paired with a compatible magnetic stirrer. Surrounding the magnet is a seamless PTFE (polytetrafluoroethylene) coating, commonly known as Teflon, which offers exceptional chemical resistance, non‑stick performance, and durability against corrosive solvents, acids, bases, and organic compounds. The compact package dimensions of 3.31 × 3.19 × 0.20 inches and lightweight design (1.59 oz) make storage and handling effortless, while the robust construction guarantees long‑term reliability. This product, model MT‑SB‑C2‑S2, has been available since December 2016 and holds a strong position in the market, ranking #23 in Lab Stirrer Bars on Amazon, reflecting its popularity among scientists and technicians.
Usage
These stir bars excel in a variety of mixing scenarios. In a typical laboratory setting, the cross‑type bars provide enhanced stability for small to medium volume vessels, reducing wobble and ensuring uniform agitation of solutions, suspensions, and emulsions. The straight‑type bars, with their longer length, are ideal for larger beakers, flasks, and reactors, delivering deep‑reach stirring that promotes efficient heat transfer and homogeneous reaction conditions. The PTFE coating protects both the bar and the vessel from chemical attack, making the set suitable for organic synthesis, analytical chemistry, biotechnology, and even educational demonstrations. In industrial applications, the bars can be employed in pilot‑scale reactors, quality‑control labs, and formulation stations where consistent mixing is critical for product uniformity. Home hobbyists benefit from the same reliability when conducting small‑scale experiments, such as DIY cosmetics, polymer synthesis, or educational kits. The set works with any standard magnetic stirrer that supports PTFE stir bars, offering flexibility across a wide range of equipment brands and models.

FAQ
What types of solvents are compatible with the PTFE coating?
The PTFE coating is resistant to most organic solvents, acids, bases, and aqueous solutions, including acetone, ethanol, methanol, hydrochloric acid, sodium hydroxide, and many others. It is not recommended for use with molten metals or highly oxidative fluorinated gases.
Can these stir bars be used with any magnetic stirrer?
Yes, the bars are designed to work with any standard magnetic stirrer that accepts PTFE stir bars. Ensure the stirrer’s magnetic field strength is appropriate for the size of the bar you are using for optimal performance.
How do I clean the stir bars after use?
Rinse the bars with de‑ionized water and a mild detergent, then dry them with a lint‑free cloth. For stubborn residues, a brief soak in a compatible solvent followed by thorough rinsing is effective. Avoid abrasive cleaning tools that could damage the PTFE surface.
What is the expected lifespan of the stir bars?
When used within recommended chemical and temperature limits, the PTFE coating and magnet core can last for several years of regular use. Periodic inspection for coating wear or magnet degradation is advised.
