Foamspin

The FoamSpin is designed to measure the ability of a liquid to generate foam by mechanically stirring the liquid. A set of rotating blades produces foam controlled by the instrument software. The blades (driven by a rotating shaft) turn at speeds of up to 6,000 rpm. The actual speed of the blades is continuously measured and controlled by the software.

Maximum rotation speed of the blades depends on the viscosity of the liquid being foamed. FoamSpin software will determine persistence of generated foam by measuring variation in its volume, density and drainage rate. The electronic cabinet allows manual control of the stirrer used to produce foam.

Measurements made by the FoamSpin

Values measured and displayed in real time:

• Mixing speed
• Foam volume,
• Volume of remaining sample liquid,
• Foam conductance at four different foam heights,
• Liquid fraction in the foam at four different foam heights.

Values calculated in real time and displayed upon completion of the experiment:

• Volume of liquid trapped in the foam,
• Foam density,
• Bikerman index,
• Volume stability of the foam,
• Liquid stability of the foam,
• Coefficient of expansion of the foam,
• Capacity for foaming,
• Retention setting (for the RUDIN test).
