Benchtop Plate Centrifuges for Separation of Serum from Blood Samples


Introduction to Benchtop Plate Centrifuges

Benchtop plate centrifuges are essential laboratory equipment used for multiple purposes, including the separation of serum from blood samples. This article aims to explore the functionality, benefits, and applications of benchtop plate centrifuges in various scientific and medical fields.

Centrifugation is a widely employed technique in research and clinical laboratories, allowing the separation of different components of a heterogeneous mixture based on their density. The process involves spinning samples at high speeds, which generates centrifugal forces that push denser particles to the bottom of the tube or well, forming distinct layers. These layers can then be carefully isolated, enabling researchers to study or utilize specific sample components effectively.

Benchtop plate centrifuges are compact and versatile instruments often preferred for small-scale applications, where space or sample volume is limited. Their design allows for convenient placement on laboratory benches or countertops, making them readily accessible for routine laboratory tasks. Although smaller in size compared to larger centrifuges, benchtop plate centrifuges can accommodate multiple samples simultaneously, increasing efficiency and reducing processing time.

Functionalities and Features

Modern benchtop plate centrifuges exhibit a range of advanced functionalities, designed to meet the diverse needs of scientific and medical laboratories. Some of the key features include:

1. Variable Speed Control: Benchtop plate centrifuges offer adjustable speed settings, allowing users to customize the centrifugal force according to their specific requirements. This feature is particularly useful when working with delicate samples or optimizing separation efficiency.

2. Timer Settings: The inclusion of a timer feature enables precise control over the centrifugation duration. Researchers can set desired time intervals, ensuring consistent results while avoiding over-spinning or excessive sample exposure.

3. Temperature Control: Certain benchtop plate centrifuges come equipped with built-in temperature control, allowing researchers to maintain a desired temperature during the separation process. This feature is especially crucial when working with temperature-sensitive samples or conducting experiments that require specific environmental conditions.

4. Programmable Presets: To simplify repetitive procedures and enhance user convenience, advanced benchtop plate centrifuges offer programmable presets. Users can save frequently used settings as presets, eliminating the need for manual adjustments and saving time.

5. Safety Features: Benchtop plate centrifuges prioritize user safety through the inclusion of various protective features. These may include automatic lid locking mechanisms, motor imbalance detection, and emergency stop functions, preventing accidents and sample contamination.

Applications in Clinical Laboratories

In clinical laboratories, the efficient separation of serum from blood samples is crucial for diagnostic testing. Benchtop plate centrifuges are extensively used in these settings due to their ease of use, compact size, and rapid processing capabilities. Some common applications of benchtop plate centrifuges in clinical laboratories include:

1. Biochemical Analysis: Benchtop plate centrifuges facilitate the separation of serum, allowing for the detailed analysis of biomarkers, enzymes, hormones, and metabolites present in blood samples. These analyses assist in diagnosing medical conditions, monitoring patient health, and assessing treatment efficacy.

2. Serological Testing: Benchtop plate centrifuges are essential for serological tests, which involve separating serum from the clotted blood. This separated serum is utilized for various tests, including autoimmune disorder diagnostics, blood typing, and detection of infectious diseases.

3. Hematology Studies: In hematology, benchtop plate centrifuges are employed to separate serum and plasma from blood samples to investigate different hematological parameters such as erythrocyte sedimentation rate (ESR), red blood cell count, or plasma component levels.

4. Coagulation Tests: The ability to separate serum rapidly is crucial for coagulation tests, which assess the blood's ability to clot. Benchtop plate centrifuges enable efficient separation of serum samples for accurate coagulation testing, evaluating factors such as fibrinogen levels, clotting time, and platelet function.

5. Microbiology Research: Benchtop centrifuges are also an integral part of microbiology research laboratories. They aid in obtaining serum or plasma samples for microbial culturing, allowing researchers to study the growth and behavior of various microorganisms.

Advantages and Limitations

Benchtop plate centrifuges offer considerable advantages over larger, high-capacity centrifuges, especially in terms of cost-effectiveness, space utilization, and operational flexibility. These devices are particularly popular in small to mid-sized laboratories or research facilities. Some key advantages include:

1. Improved Workflow: Benchtop plate centrifuges streamline laboratory workflows by allowing simultaneous processing of multiple samples. This feature enhances efficiency and productivity, enabling researchers to achieve more in less time.

2. Cost-Effective: Benchtop centrifuges are typically more affordable compared to larger centrifuge models. They require lower initial investment and incur reduced maintenance costs, involving less frequent servicing, and smaller quantities of consumables.

3. Space-Efficient: The compact design of benchtop plate centrifuges significantly saves laboratory space. This is especially beneficial for laboratories dealing with limited space availability or frequent instrument mobility requirements.

4. User-Friendly: Benchtop centrifuges are user-friendly and require minimal training or expertise to operate. Manufacturers often provide intuitive interfaces and clear instructions, ensuring ease of use for laboratory personnel.

However, it is important to consider certain limitations while utilizing benchtop plate centrifuges:

1. Capacity and Throughput: Benchtop plate centrifuges have smaller capacities compared to larger centrifuges, limiting the number of samples that can be processed concurrently. High-throughput labs or studies with a large sample volume may require multiple runs or larger centrifuges.

2. Speed Limitations: Benchtop centrifuges typically have lower maximum rotor speeds compared to larger models. This can impact separation efficiency in cases where higher rotational forces are necessary.

3. Limited Specialized Applications: Certain specialized applications may require specific centrifugation conditions or unique rotor configurations that are not commonly available in benchtop models. In such cases, larger or more specialized centrifuges may be necessary.


Benchtop plate centrifuges play a vital role in various scientific and medical fields by enabling the separation of serum from blood samples. These versatile instruments provide convenience, efficiency, and cost-effectiveness for laboratories dealing with smaller-scale operations. With their numerous features, including variable speed control, programmable presets, and safety mechanisms, benchtop plate centrifuges offer user-friendly experiences while ensuring accurate sample separation. While they may have limitations regarding capacity and specialized applications, benchtop plate centrifuges remain indispensable tools for routine laboratory tasks, clinical diagnostics, and research endeavors.
