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.
The 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.
