There are various techniques to measure the Surface and Interfacial Tensions of liquids and solutions containing surfactants.
||Time of absorption
|Bubble Pressure Tensiometer
||0.1 milliseconds to 100 seconds
|Drop and Bubble Shape Tensiometer
||1 second to hours
|Drop Volume Tensiometer
||0.2 seconds to 30 minutes
The Bubble Pressure Tensiometer is the method of choice for very short adsorption times, down to milliseconds.
The Drop and Bubble Shape Analyzer is an optical Tensiometer.
The principle of the method is to accurately determine the shape of a drop or bubble.
We offer two models:
The Drop Volume Tensiometer is a simple instrument for Surface and Interfacial Tension of liquids.
The Foam Analyzer is a unique instrument to study foam drainage and foam stability under strictly defined conditions.
Interfacial Shear Rheometer
The Interfacial Rheometer allows the study of rheology (elasticity and viscosity) at interfaces.
Ring and Plate Tensiometer TensioCAD
The TensioCAD is a semi-automatic Du Noüy Ring and Wilhelmy Plate Tensiometer for the measurement of Surface Tension and Interfacial Tension.
Oscillating Drop and Bubble Analyzer ODBA-1 for PAT-1 Tensiometer
Oscillating Drop and Bubble Analyzer for dilational elasticity and viscosity determination
Drop Pressure Module DPA-1 for PAT-1 Tensiometer
This Drop Pressure module is dedicated to measurements of Dynamic Interfacial Tensions of liquids.
Drop and Bubble Micromanipulator DBMM-1 for PAT-1 Tensiometer
The Drop and Bubble Micromanipulator is designed for the study of direct interaction between drops or bubbles.
Module for Contact Angle measurement
The CA-1 is a modular extension of the PAT-1 Drop Bubble Shape Tensiometer for contact angle measurements.
Drop and Bubble Shape Optical Tensiometer PAT-1
The Drop and Bubble Tensiometer PAT-1 uses a modern optical method to measure the dynamic Surface Tension and Interfacial Tension of liquids, 0.1 s resolution over a period of seconds up to days.
The instrument is supplied with a computer controlled dosing system.
Drop Bubble Profile Analysis Tensiometer PAT-2
Economical Drop and Bubble profile Analysis Tensiometer for the measurement of Surface Tension and Interfacial tension of liquids, equipped with a manual dosing system.
Interfacial Shear Rheometer ISR-1
The ISR-1 Interfacial Shear Rheometer allows the measurement of interfacial shear elasticity and viscosity of layers between two fluids (liquid/liquid or liquid/gas).
Foam stability and lifetime Analyzer FA-1S
The Foam Analyzer FA-1S for the study of foam drainage and foam stability under strictly defined conditions.
Drop volume Analyzer for Dynamic Surface Tension and Interfacial tension of liquids
The DVA-1 Drop Volume Tensiometer is a classical method to measure the surface and interfacial tension of liquid.
BPA-1S Bubble Pressure Tensiometer
The BPA-1S Maximum Bubble Pressure Analyzer is the choice for very short adsorption times.
