Get the highest sensitivity genomics platform.
Whether you’re discovering critical biomarkers or delivering products patients trust, Countable PCR makes it possible.
Achieve unmatched sensitivity and reproducibility
Deliver results with absolute confidence when you get true quantitation with zero bias and no sample loss. Best of all, achieve it all with scalable workflows that lower cost without compromises.
The difference is Countable.
30 million compartments
Get true isolation of single molecules for direct target quantification. Count exactly what’s in your reaction. No estimation, no subjective thresholds.
No PCR bias
With 30 million compartments and true single-molecule isolation, get clean signal that enables instant, easy multiplexing.
No sample loss
Analyze 100% of your input. With a broad dynamic range to count up to 1 million targets and sample tolerance up to 35 µL or 1 µg, find the rarest events in one reaction.
The performance is Countable.

Unlock results that were out of reach.
Get high-quality results, designed for GMP workflow
Objective & automated – no manual thresholding, every run analyzed with built-in ID Score quality metrics
Reproducible & transferable – <1%CV, simplify assay validation and transfer smoothly to production
Audit-ready – software includes secure records, audit trails, user-login and features that support 21 CFR Part 11 compliance
Multiplex instantly, without the cross-talk
Isolate every molecule – true single-molecule partitioning means every target behaves as if single-plex, for bias-free amplification
Eliminate probe balancing – no cross-talk or bleed-through across channels, so multiplex experiments work the first time
Accelerate assay development – Universal Multiplex kit delivers faster turnaround for probes, at lower cost
An all-in-one platform that supports you from idea to result.
