Selecting the right automated ELISA analyzer can significantly enhance laboratory efficiency and accuracy. This comparison between the Elisys Uno and Dynex DS2 highlights their key features to help you decide which one best meets your laboratory needs.

Analyzer Type

The type of analyzer defines its functionality and versatility in performing various assays. A fully automated system can streamline operations and improve throughput.

  • Elisys Uno: A 1-plate fully automated ELISA analyzer, ideal for smaller labs or lower throughput needs.
  • Dynex DS2: A 2-plates automated ELISA analyzer, providing flexibility and higher capacity for larger operations.

Plate Loading Capacity

The number of plates an analyzer can handle at once impacts its throughput and efficiency. Higher capacity allows for more simultaneous testing, saving time.

  • Elisys Uno: Can handle 1 plate per run, suitable for lower throughput requirements.
  • Dynex DS2: Capable of processing 2 plates, ideal for medium to high throughput needs.

Samples Positions

Indicates the number of sample tubes the analyzer can hold, affecting the volume of tests it can process at once. More sample positions enable higher throughput.

  • Elisys Uno: Accommodates 96 samples without predilution, supporting smaller batch testing.
  • Dynex DS2: Supports up to 100 samples on-board, making it efficient for larger batch testing.

Reagent Positions

The number of reagent slots determines the variety of tests the analyzer can perform simultaneously. More positions enhance flexibility in handling different assays.

  • Elisys Uno: Offers 27 positions on one reagent rack, allowing a range of tests.
  • Dynex DS2: Provides up to 8 positions for 25 mL tubes and up to 10 positions for 15 mL tubes, offering diverse testing capabilities.

Internal Barcode Reader

Automated barcode readers enhance sample tracking and identification, reducing errors and improving workflow efficiency.

  • Elisys Uno: Does not include an internal barcode reader, requiring manual tracking.
  • Dynex DS2: Features an optional barcode reader for efficient sample and reagent tracking.

Pipetting System

Critical for accurate liquid handling, the pipetting system directly affects test precision and repeatability.

  • Elisys Uno: Utilizes 1 steel needle without tips, suitable for basic pipetting needs.
  • Dynex DS2: Employs tips, providing precise liquid handling capabilities.


The type of computer (internal or external) used to control the analyzer affects its integration and ease of use.

  • Both analyzers: Utilize external computers, offering flexibility in upgrades and maintenance.


Connectivity options determine how well the analyzer integrates with other lab equipment and information systems.

  • Both analyzers: Equipped with USB interfaces, providing basic connectivity needs.

Laboratory Information System (LIS)

Integration with LIS enhances data management and workflow efficiency, crucial for modern laboratories.

  • Elisys Uno: Supports Ethernet, uni-directional communication with free definable protocol and manual execution.
  • Dynex DS2: Features LIS connectivity and integration, providing comprehensive integration with LIS systems.


When choosing between the Elisys Uno and Dynex DS2, consider your laboratory's specific needs regarding throughput, flexibility, and integration capabilities. The Elisys Uno is ideal for smaller labs with lower throughput needs, while the Dynex DS2 offers greater flexibility and higher capacity for larger operations.
