In the realm of automated ELISA analyzers, both the Elisys Quattro and Dynex DSX stand out, but understanding their specific capabilities can guide you to the right choice for your lab's needs. This detailed comparison highlights key features to consider.

Analyzer Type

Determines the operational design and automation level, impacting the analyzer's suitability for different laboratory scales. A fully automated system can significantly reduce manual intervention and increase throughput.

  • Elisys Quattro: A 4-plate fully automated ELISA analyzer, perfect for high throughput needs and reducing manual intervention.
  • Dynex DSX: A 4-plate ELISA processing system, designed for efficient processing with less automation than the Quattro.

Plate Loading Capacity

Indicates the maximum number of plates that can be loaded per run, affecting throughput and operational efficiency. Higher capacity can lead to more tests being processed in one go, saving time.

  • Elisys Quattro: Supports up to 7 plates per run, ideal for labs with high testing demands.
  • Dynex DSX: Accommodates up to 4 plates, suitable for medium-scale operations.

Samples Positions

  • Short Description: Reflects how many samples the analyzer can handle at once, impacting testing volume and speed. More sample positions allow for higher volume testing without frequent reloads.
  • Elisys Quattro: Holds up to 180 tubes, supporting large-scale testing without frequent reloads.
  • Dynex DSX: Has a capacity for 96 tubes, catering to smaller test batches efficiently.

Reagent Positions

The number of reagent slots affects the variety of tests that can be performed simultaneously. More reagent positions can increase the system's flexibility in handling various tests.

  • Elisys Quattro: Offers 60 positions on five reagent racks, allowing a wide range of tests to be set up at once.
  • Dynex DSX: Provides 57 total positions for standards and controls, optimizing reagent management but with less flexibility than the Quattro.

Internal Barcode Reader

Enhances sample tracking and identification, crucial for maintaining accuracy and efficiency in test processing. Automated barcode readers reduce the risk of human error.

  • Elisys Quattro: Simplifies workflow with basic sample ID and rack type identification.
  • Dynex DSX: Features an on-board barcode reader that tracks samples and plates throughout the process, offering advanced tracking capabilities.

Pipetting System

Key to precision in liquid handling, directly influencing test accuracy and repeatability. High-precision pipetting systems ensure consistent results.

  • Elisys Quattro: Utilizes 300 μl and 1100 μl conductive carbon tips for high precision.
  • Dynex DSX: Offers similar tip sizes but slightly lower maximum volume, maintaining precision with slightly reduced flexibility.

Number of Tips

Affects how long the analyzer can operate before needing to replace tips, impacting operational continuity. More tips mean less frequent interruptions.

  • Elisys Quattro: Can hold up to 5 racks of tips, ensuring long operational periods without interruptions.
  • Dynex DSX: Holds 432 tips across 4 racks, slightly less than the Quattro but still ample for extended use.

Onboard Capacity for Tips

The total tip storage capacity, important for labs looking to maximize uninterrupted testing periods. Larger capacity supports continuous operations.

  • Elisys Quattro: Offers a large capacity of 480 tips, enhancing workflow efficiency.
  • Dynex DSX: Also supports 432 tips, providing substantial support for continuous operations.

Computer and Interfaces

Integral for controlling the analyzer and interfacing with other laboratory systems, essential for data management. Reliable interfaces facilitate smooth data flow.

  • Both analyzers: Utilize external computers. The Quattro supports an R232 interface, while details for the DSX are not specified, indicating potential limitations in connectivity options.

Laboratory Information System (LIS)

Determines how well the analyzer integrates with laboratory information systems, crucial for seamless laboratory operations. Good LIS integration can streamline data management.

  • Elisys Quattro: Offers bi-directional communication with customizable protocol options, providing excellent integration flexibility.
  • Dynex DSX: Features an optional LIS link application, which may require additional setup but offers integration tailored to specific lab needs.


When choosing between the Elisys Quattro and Dynex DSX, consider your laboratory's specific requirements in terms of testing volume, operational efficiency, and system integration. The Quattro may be better suited for high-throughput environments requiring extensive flexibility and automation, while the DSX offers robust processing capabilities with a focus on streamlined, medium-scale operations. Evaluate these factors carefully to select the analyzer that will best enhance your lab's capabilities.
