FOAMSCAN™

Foam Analyzers and Defoamer Testers

The most accurate Foam analyzer for your Laboratory.

Liquid foams are ubiquitous in various industrial processes and in our everyday lives. Being able to generate a controlled liquid foam and understanding the phenomena responsible of its destabilization is hence crucial to optimize formulations.

 

Foaming and stability properties depend on:

  • Liquid Fraction:  liquid quantity compared to foam volume

  • Size of bubbles: from micrometer to centimeter

  • Polydispersity: distribution of bubble sizes

TECLIS range of Foam Analyzers characterizes precisely foaming properties and test defoamers effectiveness saving valuable time in foaming products formulating.

FOAMSCAN™ Foam Analyzer

foam generation methods

Several methods can be used to generate a liquid foam

  • Injecting a gas into a liquid phase through a porous media

  • Mechanical stirring, such as mixer, shaker..

  • Liquid jet recirculation

  • industrial devices such as spray can, effervescent tablet, chemical reaction.

Energy input is required but not sufficient, Surfactants play a key role on the foamability of a solution.​

Multi-scale image analysis software

FOAMSCAN Software:

  • measures precisely the volume of foam.

  • Liquid fraction and volume are determined in real time from the conductivity electrodes.

  • controls measurement parameters: Gas flow rate, stirring speed

  • Cell Size Analysis software measures bubbles 'size and distribution.​​

Foamscan™ - Foam generation by Gas Injection

The Foamscan is designed to characterize foam properties (generation and stability). Foam is generated by injecting some gas (Air, N₂, O₂, CO₂...) through the liquid.


The software controls the gas flow rate and the foam volume is determined in real time by image analysis using a CCD camera. Liquid fraction and volume are determined in real time with the conductivity electrodes. CSA software analyses the size and distribution of the bubbles.

The measuring tube is chosen depending on the applications that are studied:

  • equipped with conductivity electrodes to measure the liquid fraction of aqueous foams in real time

  • with a double glass wall to control the temperature up to 90 °C during experiment ( with optional circulating bath)

  • equipped with 4 prisms to adapt to the Cell Size Analysis (CSA) option

Applications

  • Foamability: shampoo, cream, coffee, beer, additives, formulation etc...

  • Scientific correlation with sensorial test

  • Improve formula and surfactants' screening

  • Foams for cleaning and detergents

  • Firefighting foams

  • Sparkling products

  • Flotation as a method for separating solids

  • Foam-reducing agents

Options

  • Size of the bubbles (CSA)

Foamscan™ - Foam generation by mechanical Stirring

This instrument measures the ability of a liquid to generate foam by mechanical stirring. A set of rotating blades produces foam under the control of the software. The maximum rotation speed is 6 000RPM, and depends on the viscosity of the product.

The software controls the stirring rate and the foam volume is determined in real time by image analysis using a CCD camera. Liquid fraction and volume are determined in real time with the conductivity electrodes. CSA software analyses the size and distribution of the bubbles.

Both foam generation by sparging and by mechanical stirring can be combined in the instrument.

Applications

  • Foamability: shampoo, cream, wine, beer, additives, formulation etc...

  • Scientific correlation with sensorial test

  • Improve formula and screening surfactant

  • Foam generates with shear

Options

  • Bubbles size and distribution analysis (CSA)
