Dynamic Foam Analyzer DFA100 is a unique instrument to study the foamability, foam stability/ kinetics, foam drainage and foam structure. It assists in optimization of foam forming products or in case of unwanted foam formation, helps in foam prevention. The analysis can be performed at ambient or at fixed/ with change in temperature. DFA100 is a reliable instrument for analyzing the whole spectrum from slow to very fast decaying foams. The automation program of the software provides high reproducibility & reduces user's influence on the result of the measurement to minimum.

 

Features:

• Optical structure testing of liquid foams
• Contact-free (optical) measurement of foam height
• Foam generation with controlled gas flow or by stirring
• Quick exchange of different columns and filter plates
• Sample volume from 20 ml
• Measurements also possible on very unstable foams
• Fully automatic measuring procedure
• Thermostat-able measurements up to 90°C
• Image analysis to determine the number, size and size distribution of the bubbles of a foam generated
• Both foam generation and foam decay are analyzed
• Curves of both processes are explained by a mathematical model with robust statistics
• Start of decay and time of highest decay speed
• Decay half-life value
• Decay time values for 10, 20 and 30 mm (NIBEM method)
• Decay-time-dependent foam height analogue to Ross-Miles
• Specific volume, foam capacity and foam density
• Maximum height values
• Rapid image sequence for measuring the structural changes over time, making the inner destabilisation of the foam visible long before it actually decays.
• The software provides wide functionality with user guidance oriented on the working procedure
• Time or foam-height-controlled end of foam generation and the measurement
• Parallel measurements on several columns

Applications:

• Foam development for washing & cleaning
• Firefighting
• Foams in foodstuffs & body care products
• surfactant development
• Foam inhibiting & foam reducing agents
• Foam prevention for paints & varnishes, process & waste water & cooling lubricants.

Note: Price may vary depending on configuration & accessories.

FOAM TESTING SERVICES  ARE ALSO AVAILABLE.

HPFA- High Pressure Foam Analyzer is world's only instrument for simultaneously analyzing the amount & structure of liquid foams under high pressure. It is used for studying the foamability and liquid drainage properties under extreme conditions. The measuring cell works at a pressure upto 350 bar & temperatures upto 120 degree C ,thus making it possible to observe the foam behaviour under reservoir conditions. Within one & the same measurement, it also captures the change in bubble count per area & the absolute bubble size as well as its statistical distribution.


Features:

• Measurement of foamability & foam stability based on foam height & volume with respect to time.
• Analysis of foam structure & its variation with respect to time based on size, number & statistical size distribution of the foam bubbles.
• Measurements at pressures upto 350 bar & temperatures upto 120 degree C.
• Foaming with a diverse range of gases like air, nitrogen & carbon dioxide.
• Option of adding liquids during measurement.

Applications:

• Foam assisted gas flooding.
• Foam as fracking & fracking stimulation liquid.

Note: Price may vary depending on configuration & accessories.
