Bio-Techne Ella Automated Immunoassay System

Price Range: $15,000 – $35,000 (Refurbished vs. New)

Best For:  A Budget

Primary Category: Benchtop research and clinical crossover

While floor-standing analyzers dominate high-volume hospitals, the Bio-Techne Ella remains a prominent option for smaller labs and translational research facilities on a budget. Often described as a "Next Generation ELISA," Ella utilizes a unique microfluidic cartridge system (Simple Plex) to automate the entire immunoassay workflow. This design removes the manual wash and reagent steps associated with traditional ELISA kits, reducing user error and variability without the high capital cost of larger systems.

Key Specs

• Format: Benchtop automated cartridge system.

• Time to Result: ~90 minutes.

• Sample Volume: Low volume requirement (25 µL).

• Dynamic Range: 4-5 logs, eliminating many manual dilution steps.

Performance & Applications Ella is suitable for laboratories that need high-quality data but lack the space or capital for a central lab analyzer. It bridges the gap between manual ELISA plates and fully automated clinical systems. Its sub-picogram sensitivity makes it highly relevant for cytokine profiling and biomarker discovery in neurology and oncology. Because the system is factory-calibrated, it allows researchers and clinicians to run single samples or small batches cost-effectively without utilizing entire 96-well plates.

Siemens Atellica IM 1600 Analyzer

Price Range: $40,000 – $75,000 (Refurbished) / $180,000+ (New)

Best For: Speed / Throughput

Primary Category: High-throughput central laboratory

The Siemens Atellica IM 1600 is engineered for the specific purpose of rapid sample processing. The core innovation here is the Atellica Magline Transport, a bi-directional magnetic transport system that is significantly faster than conventional conveyors. This allows for independent control over every sample, enabling STAT samples to bypass routine queues instantly. For large labs processing thousands of samples daily, the logistical speed of the Atellica system supports high-volume workflows.

Key Specs

• Throughput: Up to 440 tests per hour.

• Reagent Capacity: Onboard capacity for varying assay configurations.

• Sample Management: Magline Transport for rapid sorting and prioritizing.

• Connectivity: Scalable to connect with clinical chemistry modules.

Performance & Applications This model serves as a central analyzer for large reference laboratories and university hospital networks. Its operational strength lies in managing peak workloads without creating bottlenecks. The system supports a broad menu of assays, including complex infectious disease panels and reproductive health markers. By decoupling sample processing from assay timing, the IM 1600 ensures that urgent emergency room samples are prioritized automatically, a critical feature for trauma centers and acute care facilities.

Beckman Coulter DxC 500i Clinical Analyzer

Price Range: $80,000 – $120,000 (Estimated New)

Best For: Most Versatile

Primary Category: Integrated clinical chemistry and immunoassay

Freshly cleared by the FDA in March 2025, the DxC 500i is one of the newest entries on this list. It addresses a growing trend in laboratory medicine: the decentralization of testing. Designed specifically for satellite laboratories and independent clinics, the DxC 500i integrates clinical chemistry and immunoassay testing into a single, compact footprint. This versatility allows smaller facilities to perform a comprehensive diagnostic panel—from glucose and electrolytes to TSH and cardiac markers—on one machine.

Key Specs

• Throughput: 100 immunoassay tests/hr (plus 800 chemistry tests/hr).

• Footprint: Compact integrated design (~20% smaller than comparable standalone pairs).
