Automated Systems: Dynex DS2 - ELISA automation

Dynex DS2 (code 7000) offers all the benefits of a high-performance walk-away ELISA processing system.

The DS2 quickly and easily processes two 96-well microplates and up to 12 different assays simultaneously and features the most user-friendly control system available, chain of custody, and instrument diagnostics:

• Sample dilution and distribution
• Incubation, washing, and reagent dispensing
• Reading with automatic data reduction and quality control
• Automatic bar-code scanning

Intuitive, easy-to-use DS-Matrix ^TM which allows any lab technician to work with DS2 with minimal training.

Ingenious hardware design. The simplified system has few moving parts - one multi-function robot arm does everything from pipetting to operating the bar-code reader. In addition, the DS2’s vertical design and patent-pending multi-plate carrier save space, enabling a minimal footprint, with maximum consumable storage:

• 216 sample tips
• 96 dilution vessels in convenient 8-way strips
• 20 reagent tips
• 8 large & 10 medium reagent bottles
• 24 standard/control bottles
• Worry-free system assures accurate results.
