Drop Volume Analyser DVA-1

Classical method to measure the surface and interfacial tension of liquids
Principle is based on the accurate determination of the volume of drops detaching from circular capillaries.

Fast drop formation allows short time measurements.
DVA-1

Instrument parts
automatic dosing system - automatic refilling
temperature controlled measuring cell
data acquisition via RS-232
automatic cleaning procedure

Features of the instrument

  • very compact construction
  • 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
  • correction of the viscosity effects at short drop times
  • small size, small price, and easy to handle
