## Overview

This pack of 10 olive-shaped PTFE magnetic stir bars (8mm diameter, 20mm length) offers exceptional chemical resistance, enduring temperatures from -190°C to 250°C. Designed for professional labs, they provide non-toxic, non-stick, and long-lasting magnetic stirring performance, ensuring reliable mixing in demanding environments.

## Description

1.Name: Polytetrafluoroethylene Magnetic Stir Bars 2.Size: 8*20mm 3.Shape: Olives Shape 4.High temperature: the use of operating temperature up to 250 ¡æ 5.Corrosion resistance: for most chemicals and solvents, showing inert, strong acid and alkali resistance, water and a variety of organic solvents 6.High lubrication: the lowest coefficient of friction in solid materials 7. Low temperature resistance: good mechanical toughness, even if the temperature dropped to -196 ¡æ, can also maintain a 5% elongation 8.No adhesion: with the smallest surface tension in the solid material, no adhesion to any substance 9.Weather resistance: long-term exposure to the atmosphere, the surface and performance remain unchanged, there is B06B plastic in the best aging life 10.Non-toxic: with physiological inertia, as artificial blood vessels and organs long-term implanted in vivo no adverse reactions

Review: Durable and Long-Lasting! - I've only had to purchase this item once because of how reliable the product is. I can't say they're the best stir bar money can buy, but for the price it's definitely worth it. These stir bars have yet to lose their magnetism! My biggest problem with stir bars was always how long they stayed magnetic, these were the solution. HIGHLY recommended!
Review: Very quality, just a bit small for my needs - These are a bit small for 1.5 pint wide mouth jars, they will work but you need to use high speed. does not work with more than one with my equipment, not sure the magnet strength is high enough to work in groups of 2 or 3
