Video -based measuring with method and precision
In most diverse engineering applications the ability of liquids to wet
solids affects the quality of the
products and their manufacturing
processes. Important examples for
this are the production and application of paints and varnishes, the
development and optimization of
composite materials, the use of
adhesives and suitable solvents for
engineering materials, and the bio-
State-of-the-art optics, high-precise mechanics, fast electronic controllers, and high-resolution video
cameras guarantee all users of the

After all, our development engineers profit from more than two
decades of practical experience in
these measurement techniques.
We would like to invite you to use

drop contours in combination with
statistical error analysis. Our physicists and software development
engineers produce all their experience and creativity into the development of the software modules of
the SCA series – just for an outright
start. The available software modules are:
SCA 20 Main program
• video based measurement and
presentation of the static and
dynamic contact angle on plane,
convex, and concave surfaces,
• automatic measurement of the
contact angle hysteresis,
• recording of image sequences,
• menu controlled generation of
data sets, management, and
execution of automatic measuring procedures,
• statistics and measurement error
analysis,
• liquids and solids database with
currently more than 170 records
for all surface energy analysis
methods including related citations.
SCA 21 surface free energy
• analysis of the surface free energy
of solids as well as their components (e.g. dispersive, polar
and hydrogen bond parts, acid
and base portions, respectively)
according to nine different theories,
• representation of wetting envelopes and work of adhesion/contact angle diagrams.

Analytical values are provided by
the precise investigations of static
and dynamic contact angles, the
surface free energy of solids as
well as the surface and interfacial
tension of liquids. Last but not
least the rapid advancements in
nanotechnology and biotechno­
logy profit from the exact know­
ledge of wetting processes in the
microscopic level.

In close cooperation with customers, research institutes, and
universities we have developed
a wide range of special-purpose
extensions to the OCA instruments, to broaden the range of
surface chemistry applications in
laboratory and process applications.
LIA-MD liquid injection system
The relaxation properties of
drops on the addition of a second
liquid constituent can be studied
LIA-MD liquid injection system on an OCA 20 with
motorized y- and z-axis
with the LIA-MD liquid injection
system. In this case, a dose of a
different surface-active or chemically reactive phase is added to
an existing drop in a very short
time. The primary drop must now
18
return to the equi­librium on its
interface. In the ensuing response
time the surface and interfacial
tensions can be measured and
their behavior investigated. Developments of synthetic eye and
lung fluids for medical purposes
have already profited from this
idea, and more innovative applications are expected in the field of
protein and surfactant engineering.
Oscillating drops
For the measurement of surface
elasticities and for relaxational
studies at phase boundaries,
DataPhysics has developed the
oscillating drop generator ODG 20
and the innovative oscillating drop
generator ODG 20P with a high
resolution pressure sensor.
This extension to the optical contact angle measuring and drop
contour analysis systems of the
OCA series – based on a piezoelectric transducer – excites oscillating
drops with a wide range of frequencies and amplitudes. Periodic
variations in the drop volume, or
alternatively in the drop shape
with constant volume, can be performed. The excitation frequency
ranges up to 50 Hz, depending on
the density and viscosity of the
fluid. The amplitude of the axissymmetric oscillations varies from
micrometers to millimeters. The
oscillating drops can be analyzed
by conventional drop contour
analysis and by the new approach
of pressure measurement with
the high-performance pressure
sensor (ODG 20P).
Together with the SCA 26 the
ODG 20 and ODG 20P offers the
following measurement and calculation options:
• software controlled amplifier for
pre-defined waveforms (sinusoidal, saw tooth, rectangular, tri-
angular or arbitrary),
• constant volume mode with
axis-symmetric drop shape oscillations,
• relaxational mode following the
instant increase/decrease of the
drop volume.
• pressure measuring mode with
automatic drop volume tracking
and an increased accuracy and
resolution of the dilatational
modulus,
• analysis of the real and imaginary part of the interfacial dilatational modulus based on the
oscillating or relaxing contour of
pendant drops.
• analysis of the relaxational
modulus.
High-speed camera systems
All OCA instruments can be
extended with the high-speed
image processing system
UpOCAH with up to 1000 images
per second.
The OCA 20, 35 and 40 can

All OCA systems can be equipped
with the top view video system
TV-VS, to observe the positioning of the dispensed drop on
the surface. The USB camera
together with the high performance 6x parfocal zoom lens and
the adjustable observation angle
enables a detailed view to your

Advanced instrumentation engineered
for classical and new measuring techniques
The wetting properties of com
mon solids can be measured with
electronic tensiometers which has
been evolved to dynamic contact
angle meters. The ease of use
in providing highly reproducible
results with these instruments
has been achieved by extensive
application of internal and external computer control. Balance
based tensiometers of the DCAT
range provide a very high level of
automation in the determination
of wetting properties exhibited
by powders, fibers, and fabrics as
well as the thermodynamic prop-
design, the SVT 20N is intended
to supersede the traditionally
manual operation of these tensiometer systems.
With the additional feature of
video contour recognition and
evaluation technology, an important contribution can now be
made to research in raw materials for emulsions, encapsulated
drops, and tertiary oil recovery to
the advantage of product quality
and the preservation of the environment.
Selection of measuring bodies and accessories for the DCAT 11EC, DCAT 11, and DCAT 21
Specifically the SVTS software
package for the SVT 20N spinning

and reliable methods to evaluate
drop contours, e.g. the YoungLaplace method with statistical
error analysis, which is also used
