Surfaces and Interfaces Characterisation Suite

Kibron Inc. EZ-PI Plus Surface Tensiometer Print

We have recently taken delivery of a Kibron Inc. EZ-PI Plus Surface Tensiometer for automatic measurement of surface and interfacial tension, as well as advancing/receding contact angle measurements for wetting/dewetting characterisation of single fibres and other low mass samples.

pinnan_mittaus_8232The small footprint, portable instrument offers full PC control and a high resolution force sensor with 0.2 μg resolution. Ez-Pi Plus offers surface / interfacial tension measurements on very low sample volumes (min. 0.5 ml), ideal for when sample is limited. With an option of connection to a temperature control unit, measurements as a function of temperature can be made, as well as contact angle measurements on solid surfaces such as fibres even down to 1 μm.

Essential to our research needs in a variety of areas, the Ez-PI Plus tensiometer will be used for studying changes in interfacial tension delivered by stimuli-responsive surfactants and ionic liquids, in Pickering and micro emulsions and thin films. The capability to measure advancing/receding contact angles and hysteresis effects provides a further opportunity to assess how our stimuli-responsive surfactants interact/wet surfaces of interest which may be more difficult to assess via other techniques – thin films or tubes / textiles or fibres are particularly easy to measure with the EZ-PI plus.
