Higher accuracy, sensitivity, and absolute quantification

Powerfully simple digital PCR technology

The Applied Biosystems QuantStudio Absolute Q Digital PCR System offers a powerful yet easy-to-use digital PCR experience through its unique Microfluidic Array Plate (MAP) technology. This proprietary technology enables consistent and automated compartmentalization of a sample into 20,000 microchambers with best-in-class <1% coefficient of variation (CV). Unlike other digital PCR systems, MAP technology does not use emulsion or other droplet-based methods to compartmentalize reactions. Rather, utilizing distribution channels, the reagent is delivered to the microchambers with great precision and consistency. Additionally, the QuantStudio Absolute Q system analyzes more than 95% of the loaded sample, ensuring highly-accurate digital PCR results.

A simple workflow you already know

The QuantStudio Absolute Q Digital PCR System integrates all the necessary steps for dPCR—compartmentalizing, thermal cycling, and data acquisition—into a single instrument. Simply pipette the reaction mixture into the MAP as you would for real-time PCR, and the platform will take care of the rest. No steep learning curve and no additional steps - just the same basic workflow you are already familiar with.


Simple workflow can be completed in under 90 minutes with < 5 minutes of hands-on time.

Analyze with confidence, use with ease

Our clean and powerful data analysis suite provides a range of options for processing your data. Whether you’re visualizing multiplexed data or calculating concentrations across replicates, results can be exported for downstream analysis or compiled into an easy-to-read report in just a couple of clicks.
