Flow Cytometers

Flow Cytometers are versatile, general-purpose flow cytometry instruments that combine the analytical capabilities of flow analyzers with optional sorting functionality, making them comprehensive platforms for cell and particle analysis in research and clinical settings. These systems are foundational tools in immunology, hematology, oncology, microbiology, and vaccine development, offering flexible configurations to meet diverse laboratory needs. Flow cytometers operate by passing individual cells or particles through one or more laser beams, where detectors measure light scatter (forward and side scatter) and fluorescence emissions from labeled antibodies or dyes. This enables multiparameter characterization of cell populations based on size, complexity, viability, surface markers, and intracellular proteins. Flow cytometers can analyze thousands of events per second, providing statistically robust data for both research and diagnostic applications. These instruments are used across a wide range of applications, including immunophenotyping of T cells, B cells, and dendritic cells, cell cycle analysis and proliferation assays, apoptosis and viability assessment, intracellular cytokine detection, stem cell characterization, and microbial analysis. In clinical diagnostics, flow cytometers are essential for leukemia and lymphoma classification, minimal residual disease monitoring, HIV/AIDS CD4 counting, and transplant immunology. Modern flow cytometers support multi-laser configurations (up to 5+ lasers), high-parameter detection (10-30+ colors), and advanced features such as automated sample loading, real-time data analysis, spectral unmixing, and plate-based screening. Many systems offer modular designs that allow upgrades from analysis-only to include cell sorting capabilities, providing laboratories with scalable investment options. Wasteless Bio offers unused surplus and pre-owned flow cytometers from leading manufacturers, providing full transparency on laser configuration (wavelengths and power), detector sensitivity (PMT or avalanche photodiodes), flow rate, fluorescence channels, automation features, sorting capabilities (if equipped), and software compatibility. All listings include information on calibration status, maintenance history, and available accessories. By sourcing flow cytometers through Wasteless Bio, research institutions, clinical laboratories, and biopharmaceutical companies can access high-performance cytometry platforms at significantly reduced costs while supporting sustainable laboratory practices and extending the lifecycle of precision instruments.
