Choosing the right automated ELISA analyzer can significantly impact laboratory efficiency and accuracy. This article provides a detailed comparison of the Elisys Quattro and DiaSorin ETI-Max 3000, highlighting their key features and capabilities to help you make an informed decision.

Analyzer Type

The type of analyzer determines its operational design and automation level, which impacts its suitability for different laboratory scales. A fully automated system can greatly reduce manual labor and increase throughput.

  • Elisys Quattro: A 4-plate fully automated ELISA analyzer, perfect for high throughput needs and reducing manual intervention.
  • DiaSorin ETI-Max 3000: A 4-Plate ELISA Processing System designed to efficiently handle multiple plates, providing robust performance in various lab settings.

Plate Loading Capacity

Indicates the maximum number of plates that can be loaded per run, affecting throughput and operational efficiency. Higher capacity allows more tests to be processed simultaneously, saving time.

  • Elisys Quattro: Supports up to 7 plates per run, ideal for labs with high testing demands.
  • DiaSorin ETI-Max 3000: Capable of processing 3 full plates in minimum time, making it suitable for high-volume test processing.

Samples Positions

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.
  • DiaSorin ETI-Max 3000: Accommodates 96 tubes, suitable for medium to high-volume operations.

Reagent Positions

The number of reagent slots affects the variety of tests that can be performed simultaneously. More reagent positions 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.
  • DiaSorin ETI-Max 3000: Provides 24 positions, which may limit diversity but streamline focused testing.

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.
  • DiaSorin ETI-Max 3000: 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.
  • DiaSorin ETI-Max 3000: Offers a range of 25 – 1000 μl, providing flexibility in handling different volumes.

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.
  • DiaSorin ETI-Max 3000: Supports 41 reagent tips and 4 racks of 108, offering substantial capacity 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.
  • DiaSorin ETI-Max 3000: Does not specify onboard capacity for tips, which could affect long-term operation without resupply.

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 the details for the ETI-Max 3000 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.
  • DiaSorin ETI-Max 3000: Does not specify LIS integration details, which may limit its interoperability with other lab systems.


When choosing between the Elisys Quattro and DiaSorin ETI-Max 3000, 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 ETI-Max 3000 offers robust processing capabilities with a focus on streamlined operations.
