This magnetic stirring bar, with Alnico magnet encapsulated in PTFE coating, fits into the standard 10 mm light path cuvette and provides rapid vertical and horizontal mixing with a minimum of vortexing when placed on a magnetic stirring machine.

• Centrifugal pumping action, generated by the cross channels in the upper face, mixes without aeration
• Photometric measurements can proceed uninterrupted while reagents are added
• One-piece moulded unit will not scratch cuvettes; may also be used in test tubes
• Autoclavable
