!
We strongly advise you not to carry out the installation and work without
consulting this manual.
This manual is subject to a permanent quality control. The current version of the
manual can always be acquired from the download section of our homepage
www.kruss.de.
SPAC S PA C S PA C SPAC
The system is characterized by its high degree of flexibility. All the components
–movement axes, video system, dosing unit, environmental chambers –can be
easily exchanged or extended. All intermediate stages are possible from fully
manual operation up to PC-control of all the components.
Possible uses of the DSA100
The DSA100 measuring system –depending on the hardware and software
supplied –opens up the following possibilities:
Contact angle measurements on drops of liquid in a gaseous or liquid phase
Measurement of the surface tension of a pendant drop in a liquid or gaseous
phase
Measuring of advancing and receding drops
Evaluation of a digitized drop image by various methods
Calculation of the surface energy of a solid by various methods
Automatic control of the instrument and data recording by user-defined test
methods
Measurements at low and high temperatures

Introduction page 9
Integrated and extendable databases with substance data on liquids that can be
directly linked to the measuring data
Comfortable data management and documentation
Extendable at any time with components such as environmental chambers,
automatic axes, software-controlled optics or multiple dosing units with up to 8
syringes

page 10 DSA100 overview
3DSA100 overview
In order to measure the contact angle with the DSA100 a drop is placed on a
sample located on a moveable sample table. The drop is illuminated from one side
and a camera at the opposite side records an image of the drop.
The drop image is transferred to a computer equipped with a video-digitizer board
(frame grabber) and shown on the monitor. The DSA software contains time-
proven tools for analysing the drop image with whose help it is possible to
calculate the contact angle, surface energies and surface tensions.
In principle the DSA100 consists of three components:
The sample table with up to three mobile axes or a rotating wafer table
The video system with camera, optical system, prism, light source and aperture
A manual or software-controlled dosing unit, single or multiple
y-axis
