FAQ
Q: What materials are your stirrer bars made of?
A: They are made from chemically inert PTFE (Teflon) with a powerful magnetic core made of Alnico or rare-earth magnet for long-term performance.
Q: Are these bars compatible with all magnetic stirrers?
A: Yes. Our stir bars fit virtually all standard magnetic stirrer and hotplate stirrer brands without modification.
Q: Can they withstand heating and autoclaving?
A: Yes. PTFE coating resists temperatures up to 250°C and can be autoclaved multiple times without degradation.
Q: Do you provide different shapes and sizes?
A: We offer cylindrical, octagonal, and pivot-ring shapes in multiple lengths to match different vessel sizes and stirring requirements.
Q: What's the minimum order quantity (MOQ) for distributors?
A: The standard MOQ is 5,000 pieces per size, but we also support mixed-size bulk orders for distributors and lab equipment resellers.
