Turn your microscope into a
high-throughput sorter
DropSort processes raw fluorescence signals from PMTs, segments droplets in real time, enables multi-parameter gating, and outputs trigger signals to drive electrode-based sorting.
What is DropSort
DropSort is dedicated software for real-time signal processing and sorting in droplet microfluidics. It acquires raw optical fluorescence signals detected by photomultiplier tubes (PMTs), segments individual droplets from the continuous data stream, and analyzes intensity and size distributions across multiple channels.
Through an interactive gating interface, users define sorting criteria on measured droplet parameters. When a droplet matches the selected gates, DropSort outputs a real-time trigger signal to control an electrode for sorting.
Real-time processing
Continuous signal acquisition and droplet detection at up to 100 MHz sampling rate.
Multi-channel analysis
Measure fluorescence across up to 4 color channels, plus droplet length.
Desktop interface
Full experiment control from signal configuration to sorting, all from a single application.
Accessible FADS
Brings fluorescence-activated droplet sorting workflows within reach for teams working with droplet microfluidics.
Capabilities
Core features for real-time droplet analysis and sorting, designed around the needs of droplet microfluidics workflows.
Up to 4 color channels
Acquire and analyze fluorescence signals from up to four PMT channels simultaneously, plus droplet length measurement.
Up to 4 selection windows
Define up to four independent sorting gates to isolate specific droplet populations based on measured parameters.
Up to 100 MHz sampling
High-speed signal acquisition at up to 100 MHz sampling rate for precise droplet detection and measurement.
Measurement modes
Choose from maximum, average, and ratio measurement modes to extract the parameters that matter for your experiment.
CSV and FCS export
Export droplet-level measurement data as CSV or FCS files for downstream analysis with standard tools.
Digital lab book
Built-in experiment logging. Automatically record parameters, gate settings, and sorting statistics with timestamps.
Designed for the bench
A purpose-built interface for real-time experiment monitoring. Histograms, scatter plots, gating controls, and trigger configuration — all live.

How DropSort works
Acquire
Raw fluorescence signal from PMTs
Connect photomultiplier tubes (PMTs) to the system. DropSort digitizes and streams the raw fluorescence signal in real time.
Segment
Detect and measure droplets in real time
Droplet boundaries are detected in the continuous signal stream, isolating each droplet event with precise timing.
Gate
Analyze distributions and define sorting criteria
Extract droplet features — intensity, width, multi-channel ratios. Visualize population distributions and define sorting gates interactively.
Sort
Output trigger signal to electrode
Droplets matching the gate criteria receive a real-time trigger signal to the sorting electrode, deflecting them into the collection channel.
