Excellence in Surface Chemistry

BPA-800P – Bubble
Pressure Tensiometer
The KSV BPA-800P bubble pressure tensiometer represents the latest development in bubble
pressure measuring technology. Many of the key features are patented such as the
determination of bubble lifetime characteristics, the optimization of the aerodynamic
system, and the option to reach extremely short as well as sufficiently long measuring times.
Automatic operation and user independence are the key features of the KSV BPA-800P. Portability
and battery operation make the instrument extremely useful in industrial and environmental
applications. User friendly external PC software makes data analysis and storage easy.

Main features
• direct and precise measurement of dead time
and life time
• representation of results as a function of physical
time as well as effective adsorption time
• broad available time interval of 4 orders of
magnitude
• precise measurement of dynamic surface tension
• direct measurement of hydrostatic pressure
• correction for gravitation and liquid viscosity
• temperature measurement of the sample
• automatic detection of liquid surface
• automatic insertion of the measuring probes to
user defined depth
• portability and battery operation
• external PC connection

Fields of Application
• surfactant science

• ink jet printing
• coating technology
• foam and emulsion technology
• detergency
• pharmacy, cosmetics, food technology
• medicine and biology
• ecology
