Flow Analyzers

Flow analyzers are non-sorting flow cytometry systems used for multiparameter analysis of individual cells or particles in suspension. These powerful instruments are foundational in immunology, microbiology, oncology, hematology, and vaccine research, enabling researchers to rapidly assess cell size, complexity, and the presence of specific biomarkers using fluorescence-labeled antibodies or dyes. Unlike cell sorters, flow analyzers do not physically isolate cells. Instead, they are optimized for high-throughput phenotypic profiling, providing valuable insights into cell populations, activation states, cell cycle status, and protein expression. Flow analyzers are used extensively in clinical diagnostics and academic research, especially in immune monitoring, disease stratification, and therapeutic response evaluation. These systems operate by passing cells individually through a laser beam while detectors collect data on light scatter (FSC/SSC) and fluorescence emissions. This allows simultaneous analysis of multiple parameters—often more than 10 to 20 markers per cell—making flow analyzers a key tool for single-cell resolution studies. Common applications include T-cell and B-cell immunophenotyping, intracellular cytokine staining, apoptosis detection, bacterial viability assays, and ploidy analysis. Flow analyzers are also used in biomanufacturing to monitor cell viability and expression levels in production lines. Modern instruments support multi-laser configurations, automated sample handling, and integrated compensation and gating software. Many systems are compatible with 96- or 384-well plates, enabling screening across large sample sets in a time-efficient manner.
