Applications Conventional Stirring

Conventional Stirring Applications

There are many applications for conventional magnetic stirring ranging from simply mixing two or more compounds together, or dissolving one compound into a liquid, or mixing to speed a chemical reaction

Many of the customers who are using our Stirrus Machines (VP 706 series) do so because they need to have the power to be able to mix very viscous liquids at both slow and high speeds.
Another need is to be able to stir vessels as large as 600 gallons.
Another capability of the Stirrus Machines arises from our ability to manufacture stir elements that are specifically made to couple strongly with the Stirrus’ drive magnetic field.
We also make stir elements for our Stirrus Machines whose physical shape can be changed to match the application or shape of the vessel.
One of the unusual applications is the use of Stirrus Machines to macerate chicken embryo tissue into single-cell preparations to seed large tissue culture bottles for vaccine production.
Other customers have used the Stirrus Machines to mix slurries.
