Thin film analyzer TFA-1
Formation of microscopic foam and emulsion films, observation of their behaviour and measurements of several physicochemical parameters
Instrumental parts
Zeiss inverse microscope AXIO Observer.A1m equipped with a digital camera and
- monochromatic light source
- photo sensor module Temperature controlled measuring cell in two modifications allowing:
i) formation of a film at constant capillary pressure
ii) application of external pressure on the film
Features of the instrument
Formation of microscopic foam and emulsion films, observation of their behaviour and measurements of several physicochemical parameters
Principle is based on the well-known Thin Liquid Film – Pressure Balance Technique. Microscopic foam and emulsion films are obtained in a modified Scheludko-Exerowa cell, especially designed for best compatibility within the compact architecture of this instrument. The film thickness is measured interferometrically. The instrument is equipped with a digital camera and allows simultaneous observation of the film and measurement of its thickness, both controlled by a modern Windows software.
