BD FACSDiscover S8 Cell Sorter – BD Biosciences

Price Range: $500,000 – $750,000+ (Estimate)

Best For: High-End Innovation & Spatial Profiling

Primary Category: High-End Option

Key Specs

• Technology: Spectral Flow Cytometry + BD CellView Image Technology

• Lasers/Detectors: 5 lasers / 78 fluorescence detectors

• Sorting Speed: High-speed sorting based on image features

• Resolution: Spatial and morphological insights in real-time

Performance & Applications Released in mid-2023, the BD FACSDiscover S8 represents a paradigm shift by combining spectral flow cytometry with high-speed imaging. This instrument allows researchers to sort cells not just by fluorescence intensity but by spatial characteristics, such as the location of a protein within the cell or the interaction between two cells. This capability is revolutionary for cell biology and immunology, as it permits the isolation of specific phenotypes that traditional PMT-based cytometers cannot distinguish. It is ideally suited for core facilities requiring the absolute pinnacle of analysis power for complex applications like cell therapy development and intracellular signaling studies.

Invitrogen Attune Xenith – Thermo Fisher Scientific

Price Range: $250,000 – $375,000 (Estimate)

Best For: High-Throughput Screening & Difficult Samples

Primary Category: Speed / Throughput

Key Specs

• Technology: Acoustic Focusing + Spectral Analysis

• Sample Rate: Up to 10x faster than traditional hydrodynamic focusing

• Lasers/Detectors: Up to 6 lasers / 51 fluorescence detectors

• Clog Resistance: Designed for large or sticky cells (tumors, cardiomyocytes)

Performance & Applications Released in mid-2025, the Attune Xenith builds upon the legacy of the Attune NxT by incorporating full spectral capabilities with a massive optical upgrade. Its defining feature remains acoustic focusing technology, which aligns cells using sound waves rather than sheath fluid pressure alone. This allows for incredibly high sample input rates without compromising data variance, making it the superior choice for rare event detection and large-volume screening. The system is particularly relevant for cancer research involving dissociated tumor tissue or other "sticky" samples that frequently clog standard fluidics systems, ensuring uninterrupted data acquisition during critical high-throughput runs.

Cytek Aurora – Cytek Biosciences

Price Range: $250,000 – $450,000 (Estimate)

Best For: High-Parameter Research

Primary Category: Most Versatile

Key Specs

• Technology: Full Spectrum Profiling (FSP)

• Detectors: 64 fluorescence channels

• Lasers: 5 lasers (UV, Violet, Blue, Yellow-Green, Red)

• Sensitivity: High sensitivity due to APD (Avalanche Photodiode) technology

Performance & Applications The Cytek Aurora remains the gold standard for labs conducting deep immunophenotyping. By collecting the entire emission spectrum of every fluorochrome, the Aurora enables the use of highly overlapping dyes that would be impossible to resolve on conventional compensation-based instruments. This flexibility allows scientists to design massive 40+ color panels to characterize immune subsets with granular detail. It is a critical tool for systems biology and infectious disease research, where maximizing the information extracted from limited patient samples is paramount.

CytoFLEX SRT – Beckman Coulter

Price Range: $150,000 – $250,000 (Estimate)

Best For: Individual Labs & New Users

Primary Category: Best On A Budget (Sorter)

Key Specs

• Configuration: Benchtop Cell Sorter

• Lasers/Colors: Up to 4 lasers / 15 colors

• Setup: Automated stream setup and drop delay

• Format: Sorts into tubes, slides, or microplates

Performance & Applications The CytoFLEX SRT democratizes cell sorting by packaging advanced capability into a compact, approachable benchtop unit. Unlike large facility sorters that require dedicated operators, the SRT is designed for walk-up use by individual researchers. Its automated setup and stability controls reduce the technical barrier to entry, allowing scientists to sort their own transfected cells or CRISPR-edited lines directly in their own lab. This model is essential for gene editing workflows and cell line development where immediate, convenient access to sorting accelerates experimental timelines.

NovoCyte Penteon – Agilent Technologies

Price Range: $120,000 – $180,000 (Estimate)

Best For: Routine Multi-Color Analysis

Primary Category: Best For Reliability

Key Specs

• Detectors: 30 fluorescence channels

• Dynamic Range: 7.2-log dynamic range (eliminates need for voltage adjustments)

• Automation: Integrated autosampler for FACS tubes and plates (96/384 well)

• Software: Intuitive NovoExpress software

Performance & Applications The Agilent NovoCyte Penteon serves as an exceptional workhorse for labs processing high volumes of routine samples. Its silicon photomultiplier (SiPM) detectors provide excellent linearity and a massive 7.2-log dynamic range, effectively removing the need for users to manually adjust PMT voltages—a common source of error in multi-user environments. With its reliable walk-away autosampler, the Penteon is highly effective for QC workflows, apoptosis assays, and standard immunophenotyping in pharmaceutical development and CRO settings where consistency and ease of use are critical.
