StonyLab Magnetic Stirrer Bar Cross Shape PTFE-Coated 10x3mm

Description

Product Overview

The StonyLab 5 Pack Cross Shape Magnetic Stirrer Bar is engineered for precision mixing in demanding laboratory environments. Each bar measures 10 mm × 3 mm and is fully encapsulated in a PTFE (polytetrafluoroethylene) coating, providing a low‑friction surface that minimizes wear while offering exceptional chemical resistance. The cross‑shape geometry enhances magnetic coupling, ensuring stable rotation even at high speeds. Constructed from inert materials, the stir bars are resistant to high temperatures, corrosion, and abrasion, and they can safely endure autoclave cycles for sterilization. With a compact footprint of 0.39 × 0.39 × 0.12 inches and a weight of just 0.02 oz, they fit seamlessly into standard magnetic stirrer platforms.

Usage

These stir bars are ideal for a wide range of applications, from routine chemistry experiments to large‑scale industrial processes. Use them to homogenize solutions, dissolve solids, or maintain uniform temperature distribution in reactors, beakers, and flasks. Their PTFE coating makes them suitable for aggressive solvents, acids, and bases, while the cross shape ensures consistent stirring in viscous or low‑volume liquids. Researchers in academic labs, quality‑control technicians in manufacturing, and process engineers in pharmaceutical production will all benefit from the reliable performance of StonyLab stir bars.

FAQ

What temperature range can the stir bars withstand?

The PTFE coating is rated for continuous use up to 260 °C (500 °F), making the bars suitable for most laboratory heating applications.

Are the stir bars compatible with all magnetic stirrers?

They work with any standard magnetic stirrer that uses a magnetic field to drive stir bars. The cross shape enhances performance on both low‑ and high‑speed devices.

Can I reuse the stir bars after autoclaving?

Yes. The PTFE coating and stainless‑steel core are designed to withstand repeated autoclave cycles without loss of magnetic strength or coating integrity.

How many stir bars are included in the package?

The package contains five individual stir bars, each sized 10 mm × 3 mm, providing enough units for multiple experiments or backup stock.

What is covered by the 1‑year warranty?

The warranty covers manufacturing defects in material or workmanship. If a bar fails under normal laboratory conditions, StonyLab will replace it at no cost.
