Labgear part number LGU MSB1225/OV Oval shape Magnetic Stir bar is an oval shaped, PTFE coated, magnet which is magnetically rotated within liquid samples for unattended long duration stirring. They are also known as either egg, olive or elliptical shaped stirring bars.

Applications

• Chemical laboratory,
• Biological studies,
• Medical and research labs.

Features

• Egg shape creates more turbulence and a stronger vortex than a round, cylindrical or polygonal shape which ensures complete mixing,
• Teflon (PTFE-Polytetrafluoroethylene) casing is chemically inert, can be used with corrosive chemicals and helps to reduce friction and wear while spinning,
• Super-strong Alnico V magnets remain coupled to drive magnets—resisting spin out at high stirring speeds,
• One-piece coating of PTFE resists corrosion, heat, and cold, also ensures smooth spinning and maximum energy transfer,
• Chemically inert stir bars won't contaminate the liquid being stirred and are guaranteed to be leakproof,
• Particularly well suited for round bottom flasks,
• Does not require cleaning or sterilization after use,
• Offers minimal contact when used in plastic containers.
