Description The magnetic stirrer is constructed with a magnet encased in a PTFE coating, providing resistance to corrosion and abrasion. It is durable and chemically inert, designed to easily reach the bottom of deep containers or flasks for efficient stirring. This stir bar is a perfect accessory for use with magnetic stirrers in chemistry and biology research, as well as home laboratory applications. Features - Color: White - Material: PTFE - Size: Approximately 3.00 x 0.80 x 0.80 cm (1.18 x 0.31 x 0.31 inches), including the middle part - Width (excluding the middle part): Approximately 0.691 cm (0.27 inches) - Designed for stirring liquids or solutions in biological, chemical, and research laboratory applications - The stir bar is placed inside a container of liquid or solution that is positioned on a magnetic stirrer, which generates a rotating magnetic field using a rotating magnet or stationary electromagnets - Coated with PTFE, a chemically inert material - Suitable for use with corrosive chemicals and helps reduce friction and wear during operation - Unique shapes create different vortex patterns for efficient and effective mixing Packing List 5 x Magnetic Stir Bars
