KOMET Spinbar Stirring Bar arrow12KOMET™ Spinbar® - Stirring Bar

Improved Efficiency

The "PTFE" Komet™ Spinbar® Magnetic Stirring Bar is made from a high-energetic magnetic material. That, combined with its octagonal shape, produce exceptional power although its length is only 50mm (1.969" with a 21mm (.827") diameter. The Samarium-Cobalt magnet is encapsulated in "PTFE". Its eight edges generate strong turbulence so liquids are thoroughly mixed and its stability is not impaired in vessels with curved bottoms. In addition, the risk of demagnetization caused by external magnetic fields is completely eliminated. Komet™ transmits torque loads 2 to 3 times larger than those of conventional stirring bars of this length significantly improving efficiency.

Conveniently capture magnetic stirring bars in containers, without contaminating solution being stirred.

  • Eliminate hazard caused with stir bar splashes when decanting mixing vessels
  • Made with easy-to-clean durable polystyrene

The Spinbar® Restrainer fits in one hand. When placed alongside the outer wall of a mixing vessel, it readily attracts and holds the stirring bar in place. As vessel is drained, the stirring bar is securely retrieved from vacant vessel. The Spinbar® Restrainer is molded of easy to clean high impact polystyrene. It contains a powerful magnet that attracts and holds magnetic stirring bars up to 80mm (3") long.

technical data sheet Microwave Stirrerarrow12Microwave Stirrer

Heat and Magnetically Stir Simultaneously Inside a Microwave Oven

  • Simultaneous heating and stirring– for more consistent mixing and dissolving.
  • Speedy processing of frozen materials– for greater efficiency.
  • Purification of chemical compounds– by preparing super-saturated solutions for re-crystallization.

The Microwave Stirrer magnetically stirs inside a microwave oven by using the oven’s turntable drive spindle as the power source. Many two step-processes can now be combined for increased efficiency and productivity. Use this Microwave Stirrer with virtually any microwave oven containing a rotary turntable.

Overall measurements: 10 7/8” x 10 1/8” x 2 5/8” (276 mm x 257 mm x 67 mm)
