About PTFE Magnetic Stirrer Mixer Stir Bar Spinbar
3 Shapes Magnetic Stirrer Bars Material: PTFE (Polytetrafluoroethylene); Color: White The stir bars are coated in PTFE, which is chemically inert and will not contaminate or chemically react with the liquid. PTFE also one of the lowest coefficients of friction of any solid, which means it could reduce friction while in spinning. A set includes 5pcs stir bars in different sizes and shapes, you can select the most suitable one according to different situations and needs to ensure achieve the desired stirring results. Advantages Gear shape creates a vortex to the bottom of the container and provides more stability and less vibration than single-stir bar shapes. Cross shape creates a vortex to the bottom of the container and provides more stability and less vibration than single-stir bar shapes. The Cylinder shape stir bar is placed in a container of liquid or solution, which is seated on a magnetic stirrer, which is a laboratory device which generates a rotating magnetic field using a rotating magnet or a plurality of stationary electromagnets Recessed bezel helps to reduce vibration while stirring.Particularly Useful for Environmental Testing and Life Science Applications in Which Small Sample Volumes Need to be Prepared and Evaluated; Provides a larger surface area and added turbulence when the smooth surface of the cylindrical rods compared; Internal magnet made from alnico V, an alloy of aluminum, nickel, iron, and cobalt. Outside material is approved for use in food, drug, and cosmetic applications, it's safe; Used to stir a liquid or solution in biological, chemical, medical and research laboratory applications. Package Includes: 1x Gear Type Stir Bar: 40mm x 40mm x 7mm; 1x Cross Type Stir Bar: 37mm x 37mm x 12mm; 3x Cylinder Type Stir Bar: Length & Diameter: 25mm(1") & 7mm(1/3"); 35mm(1.4") & 9mm(0.35"); 50mm(2") & 9mm(0.35").
