This instrument allows measurements of the interfacial shear properties of layers between two fluid (liquid/liquid or liquid/gas) phases. The main principle is based on a torsion pendulum. Different measuring bodies can be used to work at liquid surfaces or at interfaces between two immiscible liquids. The ISR1 (Interfacial Shear Rheometer) from SINTERFACE allows unique shear rheological experiments. Instrument parts: • mechanical and electronic unit • temperature controlled measuring cell • data acquisition via RS-232 The instrument allows the following measurements: • frequency range between 0.2 and 0.02 Hz (depending on the measuring body and the torsion wire used) • shear elasticity and viscosity of a surface layer • time resolution about 1 minute • time dependencies over hours of adsorption time • surface shear viscosity range 1 µNs/m to 100 mNs/m • surface shear elasticity range 1 µPam to 100 mPam • temperature control in the range 10 to 50 °C Range of interfacial shear viscosity: 1 μNs/mto 100 mNs/m Range of interfacial shear elasticity: 1 μPam to 100 mPam Range of frequency: 0.2 0.02 Hz Angular resolution of torsion head: 0.01° Angular resolution of position sensor: 0.01° Data acquisition: via RS 232 Software: WINDOWS software Measuring option: adsorbed and spread layers at liquid/gas and liquid/liquid interfaces Size of device (LxWxH): 500 x 500 x 700 Weight: 40 kg Power supply: 100 … 240 AC; 50 … 60 Hz; 110 W Extra accessories: measuring body (bi-conical disc) for liquid/liquid interfaces
