TURBISCANTHE REFERENCEFOR STABILITY ANALYSISSCREENINGSTABILITY TESTS:TURBISCAN CLASSICAGEING &CHARACTERISATION :TURBISCAN LABThe Turbiscan range is world widely used in order tocharacterize the dispersion state of emulsions, suspensions,foams...Changes in terms of size and concentration (suchas creaming, sedimentation, flocculation or coalescence...)are directly monitored, in realistic conditionsenabling faster and more relevant characterizationcompared to common methods such as visual observationor centrifugation, which are time-consuming ornon-realistic.Users have now the easiest way ever to check the stabilityof their formulations with a one-click access tothe Turbiscan Stability Index ( ).TransmissionDetectorBENEFITSLight Source(Near IR)BackscatterDetectorMULTIPLE LIGHT SCATTERINGAll Turbiscans work on the same principle. This techniqueconsists in sending photons (light) into the sample.These photons, after being scattered many timesby objects in suspension (droplets, solid particles, gasbubbles, …) emerge from the sample and are detectedby the measurement device of the Turbiscan.MEASUREMENT PRINCIPLEA mobile reading head, composed of a NIR diode andtwo detectors (transmission (T) and backscattering(BS)), scans a glass cell containing the sample. TheTurbiscan software then enables to interpret the obtaineddata easily.The measurement enables the quantification ofseveral parameters, as BS and T values are linked toparticles average diameter (d) and volume fraction (ϕ).BS = f ( d /ϕ)VERSATILE TECHNOLOGYUser can study all kinds of liquiddispersions (emulsions, suspensions,foams, …), with concentrationup to 95% v/v, over a widerange of size (10 nm to 1 mm).OPTICAL AND THERMALACCELERATIONThanks to the high opticalresolution and the possibility ofimportant storage temperatures,detection of the samples ageing isaccelerated up to 200 times.NON CONTACTMEASUREMENTMeasurement is done without anymechanical or external stress, andwithout any dilution, thus allowingto monitor the ageing of theproduct in realistic conditions.EASY SAMPLE HANDLINGMeasurement is performed in adisposable glass cell, preventingevaporation or drying, requiringabsolutely no sample preparation(such as dilution).
