Dispersion in the Lab: Sometimes an Overhead Stirrer is All You Really Need
A lab mixer can consist of something as simple as a magnetic stir bar at the bottom of a beaker sitting on a stir plate. This simple stirring option is often adequate to achieve ordinary laboratory mixing tasks. But other mixing tasks may require more sophisticated blending/homogenizing technology. These more challenging tasks — perhaps involving…
Read MoreHow to Shop for an Overhead Lab Stirrer
Researchers involved in R&D lab work and pilot plant production activities along with their purchasing departments may find it necessary to evaluate the need for and importance of options available when selecting overhead stirrers. This post is designed to help you shop for an overhead lab stirrer. Among the points covered are stirring speed stirring…
Read MoreTips on Selecting a High Performance Overhead Stirrer
Overhead stirrers are highly popular mixing instruments used to blend ingredients in research laboratories and pilot plants. These units operate by means of motor-powered impellers of different configurations that perform the mixing operation. Being motor powered they can handle samples of higher viscosity than standard or hotplate magnetic stirrers operated with a different technology. In this…
Read MoreHow 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…
Read MoreUnderstanding 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…
Read MoreHow to Automate Overhead Stirrer Operations
Overhead stirrers are called upon to perform multiple mixing tasks in R&D labs. When several of these versatile overhead mixers such as offered by CAT Scientific are employed in the lab the researchers’ monitoring tasks are greatly simplified if the equipment is managed by a PC. This post describes how to automate overhead stirrer operations.…
Read MoreHow 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…
Read MoreSpecifying a High Viscosity Stirrer
Labs and pilot plants mixing high viscosity materials place special performance requirements on their overhead stirrers. Viscosity of a fluid, as defined by Wikipedia, “is a measure of its resistance to gradual deformation by shear stress or tensile stress.” It is due to friction between particles in a fluid that move at different velocities. As…
Read MoreOverhead Stirrer Operation Options
Multiple experiments or pilot plant trials utilizing overhead stirrers as part of the mixing procedures are greatly simplified when overhead mixers can be individually controlled via a computer program. This sure beats lab assistants moving up and down aisles to check on the performance of each piece of equipment. A Windows-based PC program with comprehensive…
