Drop and Bubble Micro Manipulator DBMM1

At present, we do not provide yet an instrument for direct studies of the main emulsion properties. The concept of our DBMM1, however, allows mimicking the situation in foams and emulsions, i.e. mimics the contact of two bubbles or two drops in a respective liquid medium. Also asymmetric systems like interaction of a drop and a bubble can be studied. Combined with our fast video technique HSC it is feasible to study the coalescence process between drops and/or bubbles in real time, i.e. on the scale of microseconds.
