Frequently Asked Questions

AI
PTFE-coated bars are standard for laboratory use due to their chemical resistance and non-stick properties, making them ideal for corrosive solutions. Stainless steel bars are typically used for food-grade applications, such as self-stirring mugs, where durability and ease of cleaning are prioritized over chemical inertness.
The size must match the volume of liquid and the power of your stirrer. Larger volumes require longer bars to ensure stability and effective vortex formation. Using a bar that is too small for the container may result in poor mixing or the bar floating, while one that is too large may not spin efficiently.
A stir bar retriever is an essential safety and convenience tool for laboratory settings. It allows you to safely extract the magnetic bar from hot, corrosive, or hazardous liquids using a magnetic tip, preventing direct contact with potentially dangerous substances and keeping your hands clean.
