DQ-Infinity
A digital PCR upgrade across the board — higher throughput, more flexible applications, and more accurate results.
01
Overview
VibroJet® droplet generation
Instrument-level, chip-free droplet partitioning integrates with automated amplification, imaging, and analysis.
Direct loading from qPCR formats
Load 8-tube strips or 96-well plates after the lab's existing qPCR sample preparation. No plate transfer or extra pipetting is needed at the instrument step, reducing handling, contamination opportunities, and sample loss.
Priority loading on supported models
Urgent samples can be added ahead of the routine queue on supported configurations, without waiting for a full new batch.
Ten independent PCR modules
Ten independent modules process samples in groups of eight. Configure different assay kits and targets across groups within one workflow.
Up to 384 samples in an eight-hour workday
In the high-throughput configuration, process up to 384 samples in an eight-hour workday while retaining 20 µL input per sample. Throughput is not gained by reducing sample loading volume.
FDA 21 CFR Part 11-compliant software
The operating software is FDA 21 CFR Part 11-compliant, supporting controlled digital PCR workflows.
