Drop and Bubble Micromanipulator DBMM-1

This special equipment is dedicated to studies of the direct interaction between droplets or bubbles.
This special equipment is dedicated to studies of the direct interaction between droplets or bubbles. Systems like emulsions or foams or foamed emulsions consist of ensembles of drops or bubbles or mixed drops and bubbles. The direct interaction of these entities yields information on the stability of the liquid disperse systems. The drop and bubble micro manipulator DBMM-1 fits as accessory into the profile analysis tensiometer PAT-1. The instrument gives access to the capillary pressure inside the individual drops and bubbles. It allows to manipulate the size of the two entities and to move the entities against each other to bring them into interaction. It allows the measurement of the coalescence time.

DBMM-1 Detail
DBMM-1

The instrument allows to perform the following measurements:

  • surface and interfacial tension of liqiuds (also of iso-dense systems)
  • coalescence of drop-drop, bubble-bubble, and drop-bubble systems
  • dynamic interfacial tensions in the short time range (0.01 - 100s)
  • available needles allow to form drops or bubble on a scale between 50 µm and 1 mm or more
  • drops or bubbles can be manipulated by a very fine piezo dosing system
