Buying Guide for Lab Stirrers

Lab stirrers, also called magnetic stirrers, are devices that are used to mix liquids in a laboratory setting. They usually have a magnetic bar or disk that is placed in the liquid, and this bar or disk rotates to create a stirring action. This action can be used to mix two or more liquids together, suspend solid particles in a liquid, or heat a liquid by friction. Lab stirrers are used in many different fields, such as chemistry, biology, and medicine. You can check out Amazon for more buying options.

Benefits of Lab Stirrers

Prevents Bacterial Growth

It is a common understanding that the growth of bacteria is facilitated by the presence of water. When water is present, bacteria are able to partake in a process known as binary fission, which allows them to quickly multiply in number. The process of binary fission is the primary means by which bacteria reproduce. In order to prevent the growth of bacteria, it is necessary to remove water from the equation.

Prevents Sample Contamination

Lab stirrers help prevent sample contamination by keeping the samples in constant motion. This prevents the samples from settling on the bottom of the container and coming into contact with other samples or contaminants.

Consistent Results

Lab stirrers help to keep substances from separating by providing a rotating motion that helps to mix and blend the substances together. This is done by either a magnetic or electronic motor that is used to rotate a stirring rod. This rotation creates a vortex that helps to keep the substances in suspension and prevents them from settling out or separating.

Reduces Effort Required to Stir

Lab Stirrers can help reduce the amount of effort required to stir by providing a more efficient way to stir. By using a Lab Stirrer, you can reduce the amount of time and effort required to stir, which can help you be more productive in the lab.

Factors to Consider before Buying


Size is an important consideration while buying a Lab Stirrer. The size of the Lab Stirrer will determine the capacity of the Lab Stirrer and the speed at which it can stirring.

Type of Motor

The type of motor in a lab stirrer is an important consideration because it will affect the speed, torque and power of the device. There are three main types of motors used in stirrers: AC, DC and brushless. Each has its own advantages and disadvantages that should be considered before making a purchase.

Material of Tube

Material of Tube determines the amount of heat that is conducted through the stirrer. The material also determines the chemical resistance of the tube.

Material of Base

Material of Base is an important aspect to consider while purchasing a Lab Stirrer. The three most common materials used for the base are aluminum, stainless steel, and plastic. Each material has its own set of benefits and drawbacks that should be considered before making a purchase.


A lab stirrer is a device used to mix or agitate substances in a laboratory container. The device typically consists of a motor, shaft, and stirring paddle or impeller. Lab stirrers are used in many different applications, including mixing of solutions, suspension of solids, and emulsification. To know your buying choices, head over to our featured section.
