Foam Analyser FA-1S

Characterises long time stable foams in a reasonable experimental time
by using a particular procedure - the new pressure drop technique
This is the only instrument for foam analysis based on the pressure drop technique developed by Kruglyakov, Exerowa and Khristov. The important feature is that due o the applied partial vacuum the foam in the measuring cells is essentially homogeneous over the whole foam column. In contrast to other measurement procedures, this is the prerequisite for a compare with characteristic data obtained for free foam films studied under exactly the same conditions (pressure, temperature).

foam drainage cell with conductivity sensors
foam stability cell with a candle shaped porous container

includes automatic cleaning processes

Features of the instrument

  • study separately two major processes occurring in foams: foam drainage and foam stability under strictly defined conditions
  • measure the most important foam parameter in terms of foam stability and foam lifetime at constant capillary pressure in the liquid phase of the foam
  • distinguish foams from very small differences in their stability, i.e. distinguish between stabilising ability of surfactants
  • produce foams of various dispersity and monitor the impact of dispersity on foam drainage and foam lifetime/stability
  • characterise a whole range of foams from low to extremely stable foams
  • simulate conditions in a foam similar to those in industrial foams
  • correlate foam with single foam film properties
  • monitor changes in foam dispersity occurring during an experiment
  • run express and very precise experiments
