Stirring is a crucial step in laboratory work that helps in the uniform mixing of liquids, reduction of solid particles in liquids, equal distribution of temperature and concentration, and acceleration of chemical reactions and dissolution processes. Overhead stirrers are one of the many types of stirrers used in labs, and they are known for their unique features that make them suitable for specific applications. In this blog, we will focus on overhead stirrers and their characteristics.

What is an Overhead Stirrer?
An overhead stirrer is a type of laboratory stirring device used to mix liquids. It typically consists of a motorized stirring unit that is suspended above the container holding the liquid to be stirred. The stirring unit can be controlled to rotate at varying speeds, which results in the homogenization of the liquid. Overhead stirrers are used in a wide range of laboratory applications, including chemical reactions, dissolution processes, and the reduction of solid particles in liquids. They are often preferred over other types of stirrers due to their ease of use and ability to stir large volumes ...

Parts of an Overhead Stirrer
The main parts of an overhead stirrer are:

Stirring Unit
This is the motorized part of the stirrer that rotates the stirring blade, causing the liquid to be mixed.

Stirring Blade
This is the component that is attached to the string unit and is responsible for mixing the liquid. The shape and size of the stirring blade can vary depending on the type of liquid being stirred and the desired outcome of the mixing process.

Support Arm
This is the component that connects the stirring unit to the base of the stirrer, allowing it to be suspended above the container holding the liquid.

Control Panel
This is the part of the stirrer that allows the user to control the speed and direction of the stirring unit. It typically includes buttons, knobs, or a digital display that can be used to adjust the stirring parameters.

Base
This is the component that supports the overhead stirrer and provides stability during operation.

Power Supply
This is the source of energy that drives the motor in the stirring unit. It can be either an AC power outlet or a rechargeable battery, depending on the model of the overhead stirrer.

These are the main components of an overhead stirrer, but some models may have additional features, such as temperature control or an adjustable speed range.

Criteria to choose an Overhead Stirrer
When choosing an overhead stirrer, here are six important criteria to consider:

Volume & Viscosity of the liquid
The volume of the liquid and its viscosity will determine the size and power of the stirrer needed. Some overhead stirrers are designed for small volumes, while others can handle large volumes of viscous liquids.

Stirring Speed Range
The speed range of the stirrer is important to consider because different applications may require different stirring speeds. Some stirrers have a wide speed range, while others are limited to a specific speed range.

Type of Stirring Blade
The type of stirring blade used will affect the outcome of the stirring process. Some blades are designed for low-viscosity liquids, while others are designed for high-viscosity liquids.

Control Panel
The control panel should be easy to use and provide the user with the necessary information about the stirring process. Some stirrers have digital displays that show the speed, time, and other parameters, while others have simple buttons or knobs.

Safety Features
Safety features such as an automatic shut-off or over-temperature protection are important to consider to ensure the safe operation of the stirrer.

Compatibility with other liquid equipment
If the overhead stirrer will be used in conjunction with other laboratory equipment, it is important to ensure that it is compatible with those devices. For example, some stirrers have a built-in temperature control feature, which can be useful when used with a heating mantle or other heating device.

By considering these six criteria, you can choose an overhead stirrer that is best suited for your laboratory applications.
