Reometer - Anton Paar

Contact:

Assist. prof. Mirjam Gosenca Matjaž, M. Pharm., Ph. D.

Access:

Equipment is available at the Faculty of Pharmacy, Aškerčeva 7, 1000 Ljubljana Public access to the equipment is not forseen. In any case one has to agree the details of an eventual access with its superviser which has to be present through whole agreed working time on the equipment.

Intended Purpose:

To determine the viscosity of the liquid and semi-solid delivery systems and with this associated stability testing. It is also possible to determine the plastic and elastic properties of those systems through Oscillatory rheometry and thus explain their behavior (for example, during application of creams, ointments). We used this device to determine rheological properties at interfaces, especially in the case when their characterization is important for understanding a process (eg, electrospinning to produce nanofibres) or to evaluate the system stability (the stability of emulsions). The device with a polarizing microscope enables observation of liquid crystals structures and their behavior during the rheological evaluation. The device can also be used as a 'texture analyzer', because we can measure the resistance of the pellet coating depending on the applied force.
