QX200 Droplet Reader

Use the QX200 droplet reader to count PCR-positive and PCR-negative droplets with an optical detector and thereby complete the second step of the Droplet Digital PCR (ddPCR) workflow.

Droplets are sipped, and the singulator unpacks the emulsified droplets and streams them in a single file past a two-color optical detection system in a serial manner. Up to 96 samples can be processed per run. For EvaGreen or probe-based digital PCR applications.
