Rethinking Surface Measurement

Energy Of Interactions Liquid/Solid And Liquid/Liquid

Precision is not a feature. It is the baseline.

Most contact angle systems focus on specifications.

DIGIDROP focuses on measurement integrity.

Designed for demanding laboratories and industrial environments, DIGIDROP delivers highly reproducible wettability and
surface energy data by controlling the parameters that truly impact measurement quality: optics, drop formation, baseline
detection, and data processing.

Where conventional systems fall short

Traditional instruments often rely on:

Manual alignment using micrometric screws
Limited control of drop deposition dynamics
Fixed architectures with low adaptability
Opaque data processing

The result is operator-dependent variability.
DIGIDROP addresses these limitations at the system level

Dual Motion Architecture - Precision by Design

Decoupling positioning from measurement

DIGIDROP separates two critical functions:

  • Motorized stage -> sample positioning
  • Mobile syringe -> Droplet control

Automated sample allgnment

The motoriz ed stage enables:
  • Rapid and reproducible alignment
  • Elimination of manual adjustments
  • Consistent measurement geometry
Each experiment starts from a controlled configuration.

A measurement stability strategy

This architecture ensures:
  • Reduced operator influence
  • High repeatability
  • Improved accuracy
  • Faster workf lows

Syringe mobility for critical angles (~90°)

Near 90°, measurement sensitivity increases significantly.
The mobile syringe allows:
  • Controlled droplet growth and retraction
  • Stable triple line
  • No mechanical disturbance of the sample

Result: rellable measurements In the most critical range.

Quick Insertion, No Adjustment Required

Advanced Interfacial Control - Beyond Static Measuremenl

From wettability to interfacial dynamics

DIGIDROP extends beyond static measurements through an Integrated syringe platform combining thermal regulation and
plezoelectric actuation.

Thermally regulated syrlnge

Stabilization of liquid properties
  • Elimination of thermal drift
  • Temperature-dependent measurements
Temperature is controlled at the droplet formation point.

Plezoelectric actuation

Controlled micro-oscillations

  • Dynamic Interface perturbation
  • Time-resolved measurements

Access to:

Interfacial viscoelasticity
  • Relaxation dynamics
  • Dynamic surface tension

An Integrated measurement approach

DIGIDROP enables:
  • Coupled thermal-mechanical-optical analysis
  • High-sensitivity experiments
  • Advanced characterization without additional systems

Modular Architecture - Configurable by Design

Rapid System Reconfiguration

DIGIDROP is built as a modular platform where each functional element can be repositioned or reconfigured without
complex mechanical intervention

From complete system to custom configuration

  • Optical system repositioning
  • Sample stage reconfiguration
  • Syringe module exchange or relocation
Direct access to all components

Flexibility without compromise

  • Fast transition between measurement modes
  • Adaptation to complex or non-standard samples
  • Integration of advanced modules
  • Reduced setup time

Consistent performance across configurations

  • Preserved alignment
  • Stable mechanical references
  • Repeatable positioning
One platform.
Multiple configurations.
No compromise on
measurement quality.
