Analyse des \u00e9mulsions en condition dynamique <\/p>\n

L’effet d’un tensioactif comme \u00e9mulsifiant repose sur le fait qu’il r\u00e9duit la tension interfaciale entre deux phases difficilement miscibles. Comme les tensioactifs ont besoin de temps pour agir, l’effet d’un \u00e9mulsifiant d\u00e9pend des dynamiques de m\u00e9lange. Gr\u00e2ce \u00e0 notre Drop Volume Tensiometer \u2013 DVT50, vous pouvez mesurer la vitesse \u00e0 laquelle les \u00e9mulsifiants produisent leur effet et r\u00e9duisent la tension interfaciale. Le DVT50 couvre une large gamme de processus tr\u00e8s rapides aux processus tr\u00e8s lents. Cela permet de d\u00e9terminer le comportement dynamique du m\u00e9lange ainsi que la stabilit\u00e9 d’une \u00e9mulsion \u00e0 l’\u00e9tat de repos en une seule et m\u00eame mesure. Les r\u00e9sultats de la mesure aident \u00e0 optimiser et \u00e0 doser de mani\u00e8re pr\u00e9cise les tensioactifs pour des \u00e9mulsions. <\/p>\n

Des analyses automatiques et pr\u00e9cises <\/p>\n

L’instrument analyse les \u00e9chantillons de mani\u00e8re enti\u00e8rement automatis\u00e9e et sans interruption, en remplissant automatiquement la seringue de dosage. La conception sp\u00e9ciale de notre capillaire de dosage garantit une haute pr\u00e9cision et dispense des calculs de correction qui sont habituellement n\u00e9cessaires pour les mesures de volume de goutte.
\nLe syst\u00e8me de contr\u00f4le de la temp\u00e9rature du DVT50 se distingue \u00e9galement par sa pr\u00e9cision, qui ajuste les deux phases liquides \u00e0 la temp\u00e9rature requise de mani\u00e8re uniforme et fiable. Cela permet d’\u00e9viter les variations de mesure dues \u00e0 un d\u00e9s\u00e9quilibre thermique. La grande plage de temp\u00e9rature de -10 \u00e0 90 \u00b0C permet de simuler des conditions de processus afin d’optimiser l’ajout de tensioactifs pour les conditions r\u00e9elles. <\/p>\n

Agencement variable des mesures pour diff\u00e9rents types d’\u00e9mulsion <\/p>\n

Avec le DVT50, nous avons fourni une pr\u00e9sentation flexible des cellules de mesures et des capillaires de dosage pour faciliter la simulation des proportions des \u00e9mulsions huile dans l’eau et eau dans l’huile. Les r\u00e9sultats permettent ainsi d’optimiser le type d’\u00e9mulsion pour le processus r\u00e9el. Pour r\u00e9aliser un changement rapide de l’\u00e9chantillon et le traitement d’un plus grand nombre d’\u00e9chantillons, nous avons veill\u00e9 \u00e0 ce que l’instrument soit facile \u00e0 manipuler lors du remplissage et du nettoyage. <\/p>\n

Transparence dans la mesure et la gestion des donn\u00e9es <\/p>\n

Avec des mod\u00e8les de mesures int\u00e9gr\u00e9s et flexibles, le logiciel de notre tensiom\u00e8tre, LabDesk, r\u00e9duit votre temps de pr\u00e9paration au minimum. LabDesk permet la gestion simple des r\u00e9sultats avec des sch\u00e9mas d’ensemble automatiques, des rapports de mesure complets et l’organisation de donn\u00e9es transparente. De plus, les donn\u00e9es mesur\u00e9es \u00e0 partir des diff\u00e9rents types de tensiom\u00e8tres peuvent \u00eatre trait\u00e9es dans une base de donn\u00e9es commune. Notre base de donn\u00e9es int\u00e9gr\u00e9e, compr\u00e9hensive et extensible, fait de LabDesk un ensemble de donn\u00e9es de toutes les substances importantes. <\/p>\n
