TECLIS-ITCONCEPT has specialized in the development of laboratory instruments. A set of requisites proposed as options allow the execution of measurements in different experimental conditions, in order to answer at all the specifics applications (see the options of the TRACKER and the FOAMSCAN).

The differents fields of applications are the following :

• for the TRACKER

• for the FOAMSCAN

MEASUREMENTS - TRACKER

The TRACKER is a drop tensiometer designed to the measurement of interfacial caracteristics liquid/liquid, liquid/gas, liquid/solid.

Static measurements (examples) :

• Interfacial tension liquid-liquid and liquid-solid

• Surface tension liquid-gas

Kinetic measurements (examples) :

• diffusion speed towards interfaces

• solid-liquid kinetic contact angle

• adsorption/desorption speed onto/from interfaces

Dynamic measurements (examples) :

• interfacial rheology (elasticity and viscosity of interfaces)

• liquid-solid advancing and receeding contact angles

Interaction liquid-liquid rising drop of oil in water .	Interaction liquid-gas pending bubbe of air in water	Interaction liquid-gas-solid sessile drop of water in the air on a metalic surface
Interaction liquid1-liquid2-solid sessile drop of water in oil on a PTFE surface		Interaction liquid-gas-solid sessile (up) bubble of air in water on a PTFE surface

Exemples of applications :

• food industry

  • development of food manufacturing process (sauces, low fat products, etc.)

  • quality of foams in drinks (biers, champagne, ...).

  • processing of edible oils with enzymes.

   

• pharmacy

• developpement/improvement of injectable forms.

• metabolism of the fats in living beings.

• dissolution of tablets.

 

• cosmetics

  • developpement of emulsions, creams, shampoos, etc.

   

• fine chemistry

  • paints, ink, glues, etc.

 

• petroleum industry

• bitumen.

• oil lubrication, weating agent.

• petroleum recove.

MEASUREMENTS - FOAMSCAN

The FOAMSCAN can measure the ability of a liquid to generate foams, the stability of foams, and the test of the efficiency and the persistence of the antifoaming agents.

Examples of measurements :

• Foam volume (by image analysis)

• Liquid volume in the foam

• Liquid drainage in the foam

• Foam conductance at differents heights of the foam column

• Liquid fraction at differents heights of the foam column

Exemples of applications :

• food industry

  • test on the food products (sugar, milk, etc).

  • quality of the foam in the drinks (biers, champagne, etc).

   

• cosmetics

• developpement of emulsions, shampoos, etc.

 

• detergency

• test on the washings, dishes products, etc.

• Industrie

  • optimisation of antifoams for the elimination of foams

  - in the processes (ex : paper industry, ...),
  - use of fuel,
  - etc.
