Overview
The QX700 HT ddPCR System is the latest addition to Bio-Rad's ddPCR portfolio, delivering the precision of ddPCR technology in an automated platform built for demanding, high-throughput research workflows. Combining dynamic sample loading, walkaway operation, and advanced multiplexing capabilities, it offers the flexibility and performance modern labs need.
The QX700 HT System streamlines the complete ddPCR workflow while processing up to 384 samples every 8 hours. Dynamic loading lets you add samples throughout the workday, helping maximize instrument utilization, improve laboratory efficiency, and keep workflows moving.
When to Scale Up to the QX700 HT ddPCR System
Step up from the QX700 S System to the QX700 HT System when routine volumes exceed 192 samples per run, when you need to process up to eight plates in a single run, or when continuous, walkaway operation is needed to keep pace without adding staff. With a throughput of 384 samples per run and continuous loading, the QX700 HT System enables teams to work flexibly, process large cohorts, and avoid workflow bottlenecks.

Common QX700 HT System Applications
Built for scale, the QX700 HT ddPCR System supports high-volume ddPCR applications:
Rare variant and mutation detection: run high-volume variant and MRD workflows with the reproducibility needed for production-scale research
- Liquid biopsy analysis: support large serial-monitoring cohorts with consistent, absolute ctDNA quantification
- Copy number variation (CNV): quantify vector copy number at production scale with automated, walkaway operation
- Gene expression and miRNA: generate high-throughput absolute expression data across multiple research programs
- Cell and gene therapy QC: support residual DNA, viral titer, and vector QC throughout the cell and gene therapy development lifecycle
