The Model 100SL
is an instrument with the compact
designs for budget-priced starting
into the
contact angle measuring technique
and drop shape analysis, for
the software-controlled measurement
and analysis of :
The static and dynamic contact
angle according to the Sessile
and Captive Drop method as
well as
the
analysis of the drop shape
according to the Pendant Drop
method
The wetting behavior on solid
surfaces
The surface free energy of
solids and their components
The surface and interfacial
tension out of the analysis
of the drop shape
The Model 100SL consists of
the basic hardware with the
following technical features:
Basic platform with needle
holder and syringe support
Homogeneous LED back lighting
electronics with continuously
adjustable intensity
Measuring stage , adjustable
in three axis for the accurate
sample positioning
Adjustable tilt optics

The Model 100SL Software
developed for Windows NT/2000/XP
offers by various expansion
steps:
1.
Static and dynamic contact
angle measurement according
to the Sessile and Captive
Drop method
2.
Sessile Drop method using
4 different fitting algorithms
: Laplace-Young Fitting, Circle
Fitting,
Conic Fitting, Polynomial
Fitting (Tangent Fitting)
3.
Surface tension and interfacial
tension of a liquid/liquid
system can be determined by
using the
Pendant
Drop (or Rising Bubble) method
and/or Captive Bubble method
4.
Auto baseline detection with
manual curved-surface baseline
function
5.

functions with rate of 15
fps for dynamic study like
absorption,
spreading, reaction kinetics,
software trigger function
with recording and playing
speed,
time
settings etc.
6.
Gauge ball, needle or known
liquids calibration function
7.
Result Data Center for storing,
managing, analyzing and exporting
measuring data by user-defined
tasks
or drops basis, computation
results with display items
settings and graph view
