Detailed Description
The Kruss DSA100E is a fully automated software controlled instrument for the measurement of contact angles of solids using the sessile drop method and surface tensions using the pendant method. The standard configuration can dispense 1-200μL volumes onto millimetre sized samples whereas conversion to the micro system allows smaller doses of 20pL to be dispensed onto samples in the micrometre range. The water contact angle provides valuable information on the hydrophobicity of the sample. Surface tension plays an important role in many different processes and is particularly useful for emulsion stability and determining the tendency for phases to separate.
Uses/Applications
The standard configuration is suitable for both sessile drop and pendant drop measurements for the majority of samples. Conversion from the standard into the micro configuration takes about one hour, however it allows far smaller dosing and the ability to measure the contact angle on smaller samples, for example hair fibres.
The micro configuration uses a Microdrop Technologies piezo system to dose 20 pL droplets and a more advanced x20 digital camera to capture the image before it evaporates (<1s).
