仪器简介：
Principle is based on the accurate determination of the volume of drops detaching from circular capillaries.
Fast drop formation allows short time measurements.
Instrument parts:
1. Automatic dosing system – automatic refilling
2. Temperature controlled measuring cell
3. Data acquisition via RS-232
4. Automatic cleaning procedure
Features of the instrument surface and interfacial tension of liquids
dynamic interfacial tensions in a time range of less than one second
up to several minutes complements the profile analysis tensiometry
at short times, in particular for liquid/ liquid interfaces use with any
PC or laptop no time-consuming filling procedure as it refills
automatically from a reservoir temperature controlled cell small size,
small price, and easy to handle correction of the viscosity effects at
short drop times
Fields of Application:
surfactant science, pharmacy, ink jet printing, cosmetics,
coating technology,food technology, foam and emulsion technology,
medicine and biology, detergency, ecology.
