Everyone may require an understanding of flow cytometer equipment and components for a general information purpose. Here, we’ve put together the most common components of a flow cytometer. Read below to understand the flow cytometer components.
In this approach, cells or particles in a liquid stream are transported through the flow cytometer. The fluidics system typically ensures that cells are aligned in a single flow so they flow through a laser beam. It includes:

Sample Injector
The sample injector is a part of the fluidics system that introduces the sample into the flow cytometer.
Sheath Fluid
It is another part of the fluidics system designed to maintain a stable flow and focus the sample stream.
Hydrodynamic Focusing
It is an important method in the fluidics system widely used to position cells in a narrow stream. It ensures that they flow through the laser beam individually.
The optics system is another component of a flow cytometer. It involves lasers and detectors that excite and measure the light, which is limited by the cells or particles. Here are the optics system’s components.
Lasers
Lasers are responsible for providing the light energy that is required for exciting fluorescent dyes or particles attached to cells. Typically, flow cytometers use different lasers to excite fluorescent dyes or particles.
Filters and Mirrors
Filters and mirrors are perfect optics systems in flow cytometers. They are responsible for directing and filtering the emitted light from the cells to the appropriate detectors. These optics systems components are important to separate the signals from multiple fluorescent markers.
Detectors are components in a flow cytometer used to capture the light that is emitted from the cells or particles and transform it into electrical signals. There are three types, which are as follows.
Photomultiplier Tubes (PMTs)
These detectors are responsible for detecting fluorescence signals and amplifying them.
Photodiodes
These detectors are other components in a flow cytometer. These detectors detect light with high sensitivity in some cytometers.
Forward Scatter (FSC) and Side Scatter (SSC) Detectors
These detectors provide information on cell sizes and internal complexity by measuring light scattered by cells.
The electronics and software are popular components that process and analyze the data collected by the detectors. They include:
Data Analysis Software
A data analysis software in a flow cytometer that processes the data to generate histograms, scatter plots, and other cell populations’ visual representations. This is the advanced software for a flow cytometer that performs complex analysis.
Data Acquisition System
This flow cytometer’s component captures and digitalizes the signals from the detectors.
Below are the advantages and limitations of a flow cytometer.
Here’s a closer look at the advantages and limitations of a flow cytometer.
Multiparametric Analysis
A flow cytometer allows simultaneous measurement of various parameters.
High Throughput
These flow cytometers can also analyze many cells per second.
Here are the limitations of flow cytometers.
Cost
They and associated reagents can be expensive.
Sample Preparation
The flow cytometers also have a proper sample preparation, which is essential for accurate results.
Complexity
Complexity is another limitation of a flow cytometer. The flow cytometers require expertise to operate and interpret results.
There are many applications of flow cytometry. Here’s a list of the most common applications of flow cytometry.
Cell biology is a common application of flow cytometry. It uses flow cytometry to study cell populations, their distribution, and their properties. Researchers in cell biology can analyze cell size, granularity, and fluorescence characteristics to learn more about cellular processes and interactions.
Immunology is another application of flow cytometry. In this approach, flow cytometry is employed to monitor immune responses, characterize immune cell subsets, etc. The flow cytometry also identifies and quantifies specific immune cell types.
Cancer research and diagnostics utilize flow cytometry tools to diagnose and monitor various cancers. Researchers in this application can identify abnormal cell populations, such as lymphomas and leukemias, and assess the effectiveness of treatments.
Other applications of flow cytometry are here.
Clinical Diagnostics
Clinical diagnostics is another application of flow cytometry. Many clinical laboratories utilize flow cytometry tools for routine blood tests, such as complete blood counts (CBCs) and immunophenotyping.
Cell Sorting
Flow cytometry is equipped with cell-sorting capabilities that allow researchers to isolate specific cell populations for the next process like further studying or for therapeutic applications. This process is recognized as fluorescence-activated cell sorting (FACS), which is essential for different research and clinical applications.
A flow cytometer is an invaluable and versatile tool in modern biology and medicine. This tool is the ability to measure and analyze various physical characteristics of single cells or particles as they flow through a laser beam.
With the rise of technology, flow cytometry continues to evolve, providing modern capabilities and applications. Understanding the flow cytometer’s components and functions can be daunting in scientific and clinical settings.
