Introduction
In the world of laboratory research, efficiency and precision are paramount. One tool that significantly contributes to these goals is the plate shaker. Designed to facilitate the thorough mixing of samples in microplates, plate shakers are essential for a range of applications, including biochemical assays, cell culture, and high-throughput screening. This article delves into the importance of plate shakers, their functionalities, and how they enhance sample preparation efficiency. We’ll also address common questions and share intriguing facts about these vital laboratory instruments.
Understanding Plate Shakers
What Is a Plate Shaker?
A plate shaker is a laboratory device used to mix samples contained in microplates. Microplates, also known as microtiter plates, are flat plates with multiple wells used for various assays and experiments. Plate shakers come in different designs, but they all serve the fundamental purpose of agitating samples to ensure uniform mixing.
Key Features of Plate Shakers
Plate shakers offer several features that enhance their functionality:
- Speed Control: Allows users to adjust the shaking speed according to the needs of their specific applications, ranging from gentle agitation to vigorous shaking.
- Temperature Control: Some models include heating elements, enabling simultaneous mixing and temperature regulation.
- Orbital or Linear Shaking: Plate shakers can provide orbital (circular) or linear (back-and-forth) motion, depending on the desired mixing action.
- Capacity: Plate shakers come in various sizes to accommodate different types and numbers of microplates, from single plates to multiple plates simultaneously.
Benefits of Using Plate Shakers
Enhanced Sample Homogeneity
One of the primary benefits of using a plate shaker is the improved homogeneity of samples. Consistent mixing ensures that all components of a sample are evenly distributed, which is crucial for accurate and reliable experimental results. This is particularly important in assays where even minor inconsistencies can affect outcomes.
Time Efficiency
Plate shakers significantly reduce the time required for sample preparation. By automating the mixing process, researchers can achieve thorough agitation in a fraction of the time it would take to mix samples manually. This efficiency is especially beneficial in high-throughput environments where large volumes of samples need to be processed quickly.
Versatility
Plate shakers are versatile tools that can handle various types of samples and applications. Whether you’re working with cell cultures, enzyme assays, or protein assays, a plate shaker can be adjusted to meet the specific requirements of your experiment. This versatility makes it a valuable addition to any laboratory.
Choosing the Right Plate Shaker
Factors to Consider
When selecting a plate shaker, consider the following factors:
- Shaking Speed and Motion: Choose a model with adjustable speed and the type of motion (orbital or linear) that suits your needs.
- Plate Compatibility: Ensure the shaker is compatible with the size and type of microplates you use.
- Temperature Control Needs: If temperature control is required, select a shaker with built-in heating capabilities.
- Durability and Ease of Maintenance: Look for a shaker made from high-quality materials that can withstand the demands of regular use and is easy to clean.
Popular Brands and Models
Several brands offer high-quality plate shakers, including:
- Thermo Fisher Scientific: Known for reliable and versatile plate shakers with advanced features.

FAQs About Plate Shakers
What types of experiments benefit from using a plate shaker?
Plate shakers are beneficial for a variety of experiments, including enzyme-linked immunosorbent assays (ELISA), cell culture, protein assays, and other biochemical and molecular biology assays that require thorough mixing of samples.
How do I clean and maintain a plate shaker?
To clean a plate shaker, regularly wipe down the exterior with a damp cloth and mild detergent. For more thorough cleaning, refer to the manufacturer’s instructions, as some models may have removable plates or trays that can be cleaned separately. Regular maintenance includes checking for any signs of wear or malfunction and ensuring that all components are functioning correctly.
Can plate shakers be used for non-laboratory applications?
While plate shakers are primarily designed for laboratory use, their efficient mixing capabilities can be applied to other fields, such as quality control in food and beverage industries or sample preparation in environmental testing.
