Refrigerated Centrifuges: Essential Tools in Modern Laboratories

Centrifuges are a staple in most labs. They’ve been around since the mid-1800s and are used to separate solutions based on the different properties of the elements that make up that solution. Centrifuges are often used in the medical field to separate blood, but they have many uses beyond that.

While most labs have at least one basic centrifuge, there is an upgrade you should consider: a refrigerated centrifuge. Refrigerated centrifuges combine the basic principle of centrifugation with temperature control. 

This blog will delve into the intricacies of refrigerated centrifuges, exploring their functionality, applications, benefits, and why you should consider the upgrade.

Understanding the Functionality of Refrigerated Centrifuges

So, what exactly makes a refrigerated centrifuge different from a standard centrifuge?

At its core, a centrifuge is a machine that uses centrifugal force to separate components of a mixture based on their densities. When a sample is placed in a centrifuge and spun at high speeds, the denser particles move outward to the periphery, while the less dense particles remain closer to the center. 

Refrigerated centrifuges don’t reinvent the wheel, but what sets them apart is their ability to maintain specific temperature settings during operation. They have a cooling system that can lower and maintain the internal temperature. For example, The MDX-310 has a cooling range from -9°C to 35°C. 

This feature is crucial for temperature-sensitive samples and can degrade or denature at higher temperatures, such as proteins, nucleic acids, and specific cellular components.

Benefits of Using Refrigerated Centrifuges

Temperature control is only one feature, but it comes with many benefits.

Preservation of Sample Integrity

Perhaps the most important benefit is that refrigeration improves sample integrity. Refrigerated centrifuges keep temperature-sensitive samples from degrading, ensuring accurate and reliable results.

Versatility

While you may not see the need for a refrigerated centrifuge, having one will significantly improve the versatility of your setup, allowing you to expand your capabilities immediately. These centrifuges can handle various sample types and volumes, making them versatile tools across multiple laboratory settings.

Improved Safety

Safety isn’t just an in-lab consideration when handling biological samples. Temperature control reduces the risk of sample degradation, which can lead to hazardous situations, especially in clinical and pharmaceutical applications.

What Can You Use a Refrigerated Centrifuge For?

Depending on your field, the ability to keep samples at a cold, stable temperature has a wide array of benefits and applications.

1. Biological Research

For those in biological research, there are some pressing reasons to get a refrigerated centrifuge. For one thing, many proteins require cold environments to remain stable. Refrigerated centrifuges can separate proteins from cell lysates or other mixtures without compromising their integrity.

Another reason is for DNA/RNA isolation. Nucleic acids are sensitive to temperature fluctuations, and maintaining a cold environment during centrifugation ensures the preservation of their structure and function.

2. Clinical Laboratories

Clinical laboratories should process their blood samples using refrigerated centrifuges. Blood components such as plasma and serum should be separated at low temperatures to prevent the degradation of sensitive biomarkers.

For labs that conduct urine analyses, centrifuging urine samples at controlled temperatures helps ensure accurate analysis of various compounds.

3. Pharmaceutical Industry

Drug development mandates strict control to ensure accurate results. Pharmaceutical stability studies often require centrifugation at specific temperatures to simulate storage conditions.

Producing vaccines also requires temperature control. Certain vaccines contain components that must be handled at low temperatures to retain their efficacy.

4. Environmental Science

When testing water and soil for pollutants, it’s recommended to centrifuge samples at controlled temperatures to ensure accurate readings since there are many temperature-sensitive compounds and microorganisms.

Key Features of Modern Refrigerated Centrifuges

When choosing a refrigerated centrifuge, make sure it comes equipped with advanced features designed to enhance its functionality and user-friendliness, like TOMY’s Centrifuge MDX-310

1. Digital Temperature Control

Precise digital controls allow you to set and maintain specific temperatures, ensuring optimal conditions for sample processing.

2. Variable Speed Settings

Adjustable speed settings enable the centrifuge to accommodate different types of samples and separation requirements.

3. Safety Mechanisms

Features such as automatic imbalance detection, lid-locking systems, and emergency stop functions enhance the safety of the equipment.

4. Programmable Settings

Many refrigerated centrifuges offer programmable settings for frequently used protocols, streamlining your workflow and reducing user error.

5. Eco-Mode

Refrigeration will take more energy than a typical centrifuge, so look for options that offer an eco-mode to save on electric costs.

Refrigeration Is the Way To Go

Refrigerated centrifuges are a must-have in a modern laboratory. They provide the necessary temperature control to safely and efficiently separate sensitive samples. Their applications span biological research, clinical diagnostics, pharmaceutical development, and environmental science, highlighting their versatility and importance. Refrigerated centrifuges play a crucial role in advancing scientific and medical research by preserving sample integrity, enhancing efficiency, and ensuring safety.
