The benchtop instrument that catches the errors you can't see — before they ruin your experiment.
The benchtop instrument that catches the errors you can't see — before they ruin your experiment.
Pipetting errors are the leading source of failed and irreproducible experiments. They're invisible to the naked eye, rarely caught before the damage is done, and they cost labs thousands in wasted reagents, time, and trust.
Liquid handling errors directly affect compound concentrations, assay reproducibility, and downstream data quality. Conventional pipette checks are visual and intermittent — errors often go undetected until an experiment fails. Scarlett gives you instant, quantitative confirmation after every dispense, catching deviations before they cost you time, reagents, and results.
Here's what independent validation of Scarlett at 10 µL looks like:
Validation Summary VS-001 · Independent verification conducted by VTT MIKES, National Metrology Institute of Finland · Syringe calibrated by RISE Research Institutes of Sweden per ISO 8655
How do you achieve contactless volume measurement with sub-micron resolution? The answer is light.
Polychromatic light is passed through a proprietary multi-lens system. Chromatic aberration — normally an optical flaw — is instead used as a tool. The lens stack intentionally splits white light into discrete wavelengths, each focused at a precisely calibrated distance from the sensor.
The result is a continuous rainbow of focal points — a ruler made of light, spanning from the well rim to the liquid surface with sub-micron resolution.
Only the wavelength in focus at the liquid surface reflects back with maximum intensity. The spectrometer analyzes the reflected light and identifies the peak wavelength — and since every wavelength maps to a precise distance, the peak wavelength directly encodes the surface height.
Converting liquid height to volume is non-trivial. Scarlett supports two approaches depending on your application. A calibration curve method correlates measured height profiles with known volumes for a given liquid and plate combination, delivering high accuracy where a reference curve exists. A geometric calculation method — which derives volume directly from measured well geometry and liquid height — offers a path for use cases where calibration data is not available.
The result is a highly accurate volume figure for every well — delivered in seconds, across every well format Scarlett supports.
ACCT is the core technology behind Scarlett — patent pending, built entirely by Aventix.
Request a Technical Briefing →An independent validation study conducted with VTT MIKES — Finland's National Metrology Institute and a participant in the international SI traceability infrastructure — evaluated Scarlett's ability to measure 10 µL dispensed volumes of DMSO in a 384-well microplate.
The syringe used was gravimetrically calibrated by RISE Research Institutes of Sweden according to ISO 8655 methods. Calibrated dispensed volume: 10.12 µL ± 0.07 µL (95% confidence).
All measured values across three plate rows were within ±5% of the calibrated volume — consistent with acceptance criteria applied in microliter liquid handling verification.
Scarlett uses non-contact optical sensing to measure liquid volumes across entire well plates in seconds — no consumables, no calibration liquid required.
Our AI model has been trained on thousands of liquid/plate combinations to generalize for you your plate and your liquid.
Our AI model encodes the structure of the point cloud sensor data to infer what points represent the liquid surface in your assay.
