A crucial procedure that happens in a lab is stirring. It is used to break down solid particles in liquids and homogenize liquids. Additionally, it works well to maintain the fluid's temperature and concentration. The chemical reaction and the dissolving process are accelerated by stirring liquids.
Lab stirrers come in several styles, such as large volume stirrers. Each of them has unique characteristics that increase its effectiveness for particular purposes. Overhead stirrers will be covered in this guide.
What is an Overhead Stirrer?
Laboratories often employ overhead stirrers for homogenizing, mixing, suspending, and recirculating high-viscosity substances or enormous volumes. When a magnetic stirrer is not possible, overhead stirrers are commonly used. As the viscosity changes with overhead stirrers, you can monitor a reaction's effect.
Different Parts of an Overhead Stirrer
The stirrer, along with paddles, rods, and stands, makes up an overhead stirrer. One of its key components is the paddle. Depending on the stirring motion, speed, turbulence, and flow they produce, the various varieties of paddles are employed for various applications.
Top Factors to Consider Before Choosing An Overhead Stirrer
Viscosity
The term "viscosity" describes how thick a fluid is when stirred. Additional torque is required from the motor stirrer when mixing due to higher viscosity. The stirrer needs to keep going despite the changing viscosity conditions. Ensure that the overhead stirrer can manage your batches' highest viscosities.
To make this determination, you must be aware of the viscosity ranges you will be stirring. Will it have a low viscosity, an average viscosity, a high viscosity, or none at all?
Torque
Torque is the rotational force needed on a rotor and increases fluid pressure and flow. The efficiency by which the stirrer can continue to rotate in highly viscous mixtures increases with increasing torque. Any increase in speed and diameter necessitates more power and affects your torque.
Interface
To connect to a PC, do you require an interface?
There are overhead stirrers that can be operated by an external device, such as a computer, and include programmable mixing and data logging capabilities.
Stirring Speed
By model, stirring rates can vary. Stirrers often offer a single speed or a range of speeds. Think about the speeds required for the mixing you regularly do. Having an overhead stirrer with a digital speed display is really useful.
Stirrer Accessories & Options
Do you require any extras, options, or features?
There are reversible models available for churning in both clockwise and counterclockwise directions. Automatic shutdown programmed mixing, a stand, zero torque, a light, a timer, a speed display, and a digital torque display are additional elements to consider.
