  • Scientific correlation with sensorial test

  • Improve formula and surfactants' screening

Options

  • Automatic Cleaning

  • Size of the bubbles (CSA)

  • Sampler (Automatisation of the device) 

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

All values measured are the same as values measured with the Foamscan. Only the foam generation mode is different. 

 

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

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.

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

 

The Foamspin can be sold as a stand alone or integrated with a Foamscan as an option.

Foamspin™ - Foam generation by Stirring

Applications

  • Foam generation by Jet

  • Anti-Foam test

  • Oil&Gas

  • Fuel 

  • Home & personal care

Options

  • Automatic Cleaning

  • Injection chamber (antifoam)

  • Solvant resistance

A jet of sample is directed downwards into the glass tube to generate foam. Inlet of the circulation pump is at the base of the glass tube, well below the foam. The pump drives the liquid sample to supply the jet. A video camera takes images of the foam.  The software analyses images to determine foam volume.

Glass tubes are composed of a double wall allowing to control the temperature of both the liquid jet and the foam, using a heating circulator. 

After the experiments, the sample can be removed automatically by the pump.

The Foamscan HTHP is designed to measure the ability of a liquid to generate foam by sparging a gas through a liquid at high pressure and high temperature.

The foam is generated in stainless steel cell

Foam tube encloses the foam probe and the support of the glass frit in a stainless steel cell which is mounted into the measurement unit of the Foamscan HP. The frit is installed at the bottom of the foam tube. The gas is injected through the glass frit by a flowmeter. A thermocouple measures the temperature inside the cell. The temperature control is achieved by resistance heaters built into the environmental chamber walls.

Measurement of foam volume using foam probe

The probe monitors the foam's height. When probe and foam are connected, an electrical current circulates between the probes, making a conductance loop between the probe position and height of the foam and that measures the foam height or foam volume.

The Foamscan DEPR is designed to measure the ability of a liquid to generate foam by sparging (or bubbling) a gas through a liquid or by depressurization. It also determines persistence of the generated foam by measuring variation in its volume, density, and drainage rate.

 

The Foamscan DEPR is equipped with a double jacketed removable glass tube. The instrument works at a temperature up to 120°C and an overpressure up to 8 bar.

A flowmeter operating up to 5000 mL/minute is connected to the bottom of the cell. The gas is injected into the tube through a glass frit. The gas flow is regulated depending on the pressure inside the tube. An overpressure up to 8 bar can be applied within the tube and a pressure regulator controls and maintains the pressure during the experiment.
