The Rheonix CARD is advancing the adoption of molecular diagnostics through it's innovative simple, yet functional design which delivers a fully automated molecular device at a fraction of the cost of competitors.

The Rheonix CARD fully automates nucleic acid amplification tests from raw sample input thru detection.

The design of the CARD allows for the simultaneous testing of four patient samples enabling greater workflow efficiencies than competitors. Each sample is atomically applied to the CARD where it is extracted, purified, amplified and detected. All waste is contained on the CARD.

The CARD moves fluid from step to step through each process by using microfluidic channels, pumps, and valves integrated into the lower layer of the device. By sequentially applying positive and negative pressure to this lower layer, valves can be opened allowing fluid to travel to a pump where positive pressure is applied to force the fluid to the next step in the process.
The upper layer of the device is a reservoir that holds reagents used in the extraction, purification, amplification and detection process. The same principals of positive and negative pressure applied to the lower laminate layer of the CARD are used to move and mix reagents.

Rheonix is advancing the adoption of molecular diagnostics by addressing key issues such as capability, applicability and affordability of these tests.
