Features & Benefits

Fully Automated

The DS2 is a fully automated and compact system ensuring laboratory efficiency as it quickly and easily processes two 96-well microplates and up to 12 different assays simultaneously. 

Fully Integrated Washing

The DS2 Microplate Reader has a fully integrated washing system allowing incubation, washing and reagent dispensing with minimal effort required. 

Extensive On-Board Software

DS Matrix™ Software powers the DS2 reader providing a simple, graphical interface which can be operated by any lab technician with minimal training by simply following prompts. 

Compact System

The vertical design of the DS2 Microplate Reader provides a space saving solution for any laboratory, while the patented multi-plate carrier ensures optimal throughput.

Instrument Diagnostics

On board instrument diagnostics ensure that the DS2 Microplate Reader is operating at optimal levels to ensure efficient operation in laboratories.

Automated Barcode Reading

The DS2 Microplate Reader has a barcode reading system on board for all samples and reagents which increases walk away time for laboratory technicians.
