The company DataPhysics Instru-

ments GmbH was founded in

1997 in Filderstadt near Stuttgart,

Germany, by specialists with many

years of experience in surface

chemistry. Since then our scien-

tists and engineers have been

developing in close cooperation

with customers throughout the

world, including science and

research institutes, new measur-

ing instruments and systems for

investigating the processes of sur-

face chemistry in laboratory and

process applications. Our primary

objective is to translate the power

of innovation into the advance-

ment of measurement and inter-

facial engineering and to developsuperior products for demand-

ing customers. As a result, we

have created a corporate culture

that motivates competent and

creative staff in all departments

to join forces for the best results

in a common goal: perfection. If

you want to know more about

surface chemistry or the company

DataPhysics, simply ask for our

booklet ‘Surface Chemistry – An

attractive science’ or download

the PDF file from our web site. In

this booklet, the DataPhysics team

escorts you through the fascinat-

ing world of surface chemistry,

with a wealth of background

information on engineering, the

measuring techniques, and refer-

ences to key literature on a multi-tude of applications.

DataPhysics is specialised in the

development of high-precise and

reliable methods for evaluating drop

contours in combination with sta-

tistical error analysis. Our physicists

and software development engi-

neers 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, including

• 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,

• store of image sequences,

SCA 23 — software for evaluating liquid lamella

In most diverse engineering

applications the ability of liquids

to wet solids affects the quality

of the products and their manu-

facturing processes. Important

examples for this are the produc-

tion and application of paints and

varnishes, the development and

optimization of composite mate-

rials, the use of adhesives and

suitable solvents for engineer-

measurement of all interfacial

parameters, for the most diverse

applications, at temperatures from

-30…1800 °C and from high-vacu-

and other physical parameters can

be acquired directly by the OCA

instruments or with additional me-

ters, directly connected to the PC.

Devices for environmental and

temperature control

The TFC 100 is a liquid tempera-ture control unit for the tempera-

ture setting from - 10…130 °C by

an optional liquid circulator bath

and under protective atmosphere

(inert gas inlet). The triple diffuser

TDI 100 is a recommended attach-

ment for working temperatures

below room temperature to pre-

vent condensation by directing a

dry gas flow towards the chamber

windows. The TFC 100 is expand-

able with a humidity sensor.

The TPC 150 is a temperature control

chamber with a peltier system for

the software controlled tempera-

ture setting from -30…160 °C (heat

up and cool down rate ±1 K/s), also

under protective atmosphere (inert

gas inlet). The triple diffuser TDI 150

is a recommended attachment

for working temperatures below

room temperature to prevent con-

densation by directing a dry gas

towards the chamber windows.

The TPC 150 is expandable with a

humidity sensor.

The TEC 400 and TEC 700 are tem-perature control chambers with

twin electric resistance heater for

the software controlled tempera-

ture setting up to 400 °C re spec-

tively 700 °C, also under protec-

tive atmosphere (inert gas inlet).

The NHD 400 an NHD 700 are

electrical needle heating devices

for generating drops at tempera-

tures up 400 °C respectively 700 °C

(i.e. polymer and hot melts, molten

metals, dosing of high viscous

liquids etc.). Also extremely tena-

cious copolymers with viscosities in

the kPas range, e.g. with elastomer

constituents, can be dosed easily.

The MTF 1200 and HTFC 1800 are

electrical heated high tempera-

ture furnaces for the manual or

software controlled temperature

setting up to 1800 °C under pro-

tective atmosphere. The special

‘LHT’ versions of the OCA-series

are designed for use with the high

temperature furnaces.

The HTFQ 1200 HV is a high tem-

perature (up to 1200 °C) and high

vacuum system (down to 1 mPa).

The PMC-50S is a high pres-

sure system for up to 80 °C and

5·106 Pa.

Software for environmental and

temperature control

The SCA 20 software, developed

for Windows XP®/Vista®, supportsall the temperature and environ-

mental control systems. This

software features simple and

intuitive usability and control of

all hardware components. Up to

four measured temperatures can

be stored, presented and analyzed

(in Celsius, Fahrenheit or Kelvin).

Individually programmable tem-

perature sequences allow the

automatic control, analysis, and

presentation of temperature

sweeps for sessile drop, pendant

drop, and lamella analysis without

user interaction.

The software module SCA 23 is

an unique way to determine the

surface tension of high-viscous

materials by analyzing the lamella

contour. In particular, the analysis

of polymer and metal melts or

In close cooperation with cus-

a wide range of special-purpose

extensions to the OCA instru-

surface chemistry applications in

laboratory and process applica-

tions.

The relaxation properties of

drops on the addition of a second

have already profited from this

idea, and more innovative applica-tions are expected in the field of

This extension to the optical con-

contour analysis systems of the

OCA series – based on a piezoelec-

tric transducer – excites oscillating

drops with a wide range of fre-

quencies and amplitudes. Periodicvariations in the drop volume, or

alternatively in the drop shape

with constant volume, can be per-

formed. The excitation frequency

ranges up to 50 Hz, depending on

the density and viscosity of the

fluid. The amplitude of the axis-

symmetric oscillations varies from

All OCA systems can be extended

with the high-speed image pro-

to 1000 images per second.

The OCA 20, 30, 35 and 40 can

be upgraded with the high-

speed image processing system

UpHSC 1000 (up to 1600images per second), or with the

UpHSC 2000 (up to 2200 images

per second). Both UpHSC uses

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 exter-

nal computer control. In addition,

instruments such as the tensio-

meters DCAT 11EC, DCAT 11, or

DCAT 21 provide a very high level

of automation in the determi-

nation of wetting properties

exhibited by powders, fibers, and

video-based measuring instru-

ments from DataPhysics. In a

compact design, the SVT 20N is

intended to supersede the tradi-

tionally manual operation of these

tensiometer systems.

With the additional feature of

video contour recognition and

evaluation technology, an impor-

tant contribution can now be

made to research in raw materi-

als for emulsions, encapsulated

drops, and tertiary oil recovery to

the advantage of product quality

and the preservation of the envi-

ronment.
