Contact Angle Meters
OSC92LJ111
Features
-Sessile drop method - fast image capture
It enables sequential measurements and
automatic recognition of droplet deposition.
60 or 30FPS standard & 1000FPS option
Application:
initial spreading, absorbing property, effect of surface active agent
-Extension/contraction method
Advancing/receding angles are measured in response to increasing/decreasing the
volume of captive droplet. Automatic dispenser AD-300s (option) is required for
smooth dynamic motion by volume change.
Application: coating property, repellency, characterization of hysteresis
-Surface free energy analysis of solids
Solid surface free energies and their components are analyzed from the results of contact angle with probe liquids.
Geometric mean, Harmonic mean, acid-base, Interaction analysis (Work of adhesion, Interfacial free energy),
Young-Dupr?, Zisman are available. Surface energy kit (option) is recommended for quick starting.
Application: adhesive property, characterizing surface modification, digitalizing hydrophilicity/hydrophobicity
-Surface/interfacial tension of liquids
Pendant drop method is adopted and its advantages compared with
conventional Wilhelmy plate and du No?y ring methods are:
-measurement with small liquid amount (less than 1mL)
-high temperature control (e.g. molten polymer applications)
-good for solutions that change surface quickly by exposure in the air
Pendant drop kit (option) is required.
--Sliding method
Advancing/Receding Angles are measured while tilting the stage. An angle of
a droplet starting sliding is determined as Sliding angle and Adhesive energy
between the droplet and the solid surface is analyzed at the same time.
Sliding kit (option) is required.
Application: repellency/hydrophobicity, characterization of hysteresis
-Dynamic sliding method
It characterizes speed and acceleration of droplet sliding
Application: repellency/hydrophobicity, characterization of hysteresis
-Automatic recognition of droplet deposition
-Live image & Focusing aid
-Droplet volume monitoring
-Threshold level adjustment
-Data chart & variable data
-Movie converter
-Standard droplet sample
-Every model includes it for periodical calibration and inspection.
