The PTFE Magnetic Stirrer Rod in Standard Shape is designed for reliable laboratory mixing and precision formulation. Its strong magnetic core provides stable coupling with magnetic stirrers, while the smooth PTFE coating creates a chemically resistant contact surface that is easy to clean.
The classic cylindrical shape supports consistent rotation and efficient mixing in common laboratory vessels. Suitable for dissolving ingredients, homogenizing formulations and maintaining uniform suspensions.
Selected for laboratory-grade coating quality, clean finishing and dependable magnetic performance. Resistant to temperatures up to 250°C and available in multiple sizes for different vessels and mixing volumes.

Do you know what is inside your stirrer rod?
A magnetic stirrer rod remains in direct contact with your entire formulation. Unknown core materials and inconsistent PTFE coatings can therefore introduce avoidable contamination risks.
Unverified low-cost rods may create an avoidable risk
Products from unreliable sellers may be supplied without dependable information about PTFE quality, coating thickness, magnetic-core composition or manufacturing controls. A thin, uneven or easily damaged coating can increase the possibility of unwanted contamination.
Trace amounts of heavy metals in low-quality rods
Low-quality stirrer rods from unreliable or unverified sellers may use poorly controlled magnetic-core materials, manufacturing processes or PTFE coatings. If the coating is thin, porous, uneven or damaged, trace amounts of metals from the core or production process may potentially reach the formulation.
Faster wear, scratches and retained cleaning agents
Lower-quality PTFE coatings may be thinner, less uniform or more vulnerable to scratching and abrasion. Damaged areas can retain residues from previous formulations as well as traces of detergents, alcohols, solvent cleaners, disinfectants, acids or alkaline cleaning solutions used to clean the rod.
Unverified marketplace products
- Unknown PTFE purity and coating thickness
- Unknown magnetic-core composition
- Potential trace-metal contamination risk
- Greater risk of premature scratches and wear
