Phased Magnetic Cylinder, to Reduce “Knocking” at Low Speeds, 432 mm long Magnet

Seventeen 10.589 degree phased 48 MGO neodymium magnets (1.25″ x 1.25″ x 1″) in a 2.25″ diameter tube. heat stable to 80C.

Alligator Vertical Tumble Stirrers

The Alligator Magnetic Vertical Tumble Stirrer uses patented stir-cylinder technology to mix large numbers of samples in tubes, vials, bottles, and microplates (USA Patent #6,176,609). Instead of spinning a magnetic stir bar about the horizontal plane like the standard magnetic flask stirrer, the Alligator Vertical Tumble Stirrer causes stir elements of all sizes and shapes to tumble vertically end-over-end inside each well or vessel. The Alligator Vertical Tumble Stirrer will stir all types of microplates of any volume or format. It will also stir V and U bottom microplates, PCR plates, micro-centrifuge tubes, test tubes, syringes, vials and bottles, and special designed troughs and reservoirs. Perhaps the best way to appreciate how the Allligator Vertical Tumble Stirrers function is to see all the videos above this section.

Advantages of the Vertical Tumble Stirring System

Many Models available

Using the most powerful permanent magnets manufactured, we make many different models of Vertical Tumble Stirrers to fit the many varied applications and requirements of our customers. Requirements for heating and continuous stirring for a long period of time demands special Vertical Tumble Stirrers that are resistant to heat and with motors capable of working under high loads for extended periods. We make our Vertical Tumble Stirrers heat resistant using Mica. The Mica deck will accommodate three of our V&P heat blocks operating at 200C. Please check with our knowledgeable staff to help you make the appropriate selection for your application. Our specialty is flexibility- let us know if you have a custom application today!
