Frequently Asked Questions

AI
PTFE (Teflon) coated bars are chemically inert and ideal for laboratory use with aggressive solvents. Stainless steel bars are durable and commonly used in consumer products like self-stirring mugs or for mixing food-safe liquids where corrosion resistance is key.
The bar size must match your vessel volume and viscosity. Larger bars are needed for higher volumes or thicker liquids, while smaller bars suffice for low-volume, low-viscosity mixtures. Check your stirrer's maximum capacity to avoid motor strain.
Generally, no. Metal components in magnetic bars can cause arcing or damage the microwave. PTFE-coated glass or ceramic bars may be safe, but always verify the manufacturer's specifications before placing any magnetic device in a microwave.
