High temperature resistance, maximum working temperature is up to 250. Corrosion resistance, stir bars are chemical inert to most chemicals and solvent, such as strong acid, alkali, water and organic solvent. High lubrication, stir bars have the lowest friction coefficient among solid material. Low temperature resistance, they have good mechanical toughness, and will keep 5% elongation even at -196. No adhesiveness, they have the lowest surface tension among solid material, and will not stick to any substance.
Size: 5×15mm; 7×30mm; 9×30mm (Optional)
Package Includes:5 × Stir Bars
