How Dynamic Viscosity Overhead Stirrers Work

Dynamic viscosity overhead stirrers are designed, in slang terms, to “go with the flow.”  What we mean here is that their power systems can accommodate an increase (or decrease as the case may be) of sample viscosity. In this post we’ll take a look at what goes into these precision lab devices and how they…

Understanding Overhead Stirrer Terms

What’s “fuzzy logic?” It’s not a description of the “thinking” that seems to go on in Congress, but instead a term applied to a way technical equipment is automatically controlled.  In this post we list many of the terms you’ll need to know when you shop for an overhead lab stirrer.  Why You Should Understand…

How to Maintain Laboratory Overhead Stirrers

Laboratory overhead stirrers are one of two widely used instruments to mix ingredients in product research labs. CAT Scientific lab overhead stirrers, also called overhead mixers, have motor-powered stirring tools immersed in the sample beaker*.  The configuration of the stirring tools – generally termed impellers, paddles and blades – is selected based on the task…
